Safety regulations

- 27 - ENGLISH 5

1.3 Fuelling

Petrol is very light and highly flammable. Keep away from open flames and never spill fuel. Do not

smoke at the operating site or at and near the refuelling site!

• Stop the engine prior to refuelling.

• Let the engine cool down before refuelling - fire risk!

• Open the tank lid slowly to allow any excess pressure in the tank to be reduced without the risk of petrol

spraying out.

• Fuel may contain substances similar to solvents. Prevent products made from mineral oil coming into

contact with skin and eyes. Wear protective gloves during filling with fuel. Frequently change and clean

protective clothing.

• Avoid breathing in fuel vapour.

• The refuelling site should be well ventilated.

• Avoid any soil spillage of fuel or oil (protection of the environment). Use a suitable mat.

• Immediately clean any spilled fuel on the machine. Change contaminated clothing without delay.

• Always tighten the fuel tank cap firmly by hand without using any tools. The fuel tank cap must not be able

to work itself loose as a result of the vibrations of the engine.

• Check for petrol leaks. Do not start the machine or work with the machine if there is a petrol leak. Life

threatening risk from burns!

• Store fuel and oil in approved and correctly labelled containers.

1.4 When transporting the equipment

• When carrying the chainsaw for short distances (from one working area to the next), always apply the chain

brake so that the chainsaw is blocked (preferably switch the engine off as well).

• Never carry or transport the power tool while the cutting tool is running.

• When transporting the device over longer distances, always switch the engine off and attach the chain

guard.

• To prevent leakage of fuel or oil and damage in general, make sure that the device is secured so that it

cannot fall over when it is transported in vehicles. Check the fuel and chain lubrication tanks for leaks.

Ideally you should drain the tanks prior to transport.

• Always empty the tanks before dispatching the unit.

1.5 Notes on assembly, cleaning, adjustment, maintenance and repairs

• The power tool must not be assembled, maintained, repaired or stored in the vicinity of naked flames.

• The engine must be switched off and the stop switch set to "0“ for the duration of all work performed on the

guide bar and saw chain (for assembly, cleaning, maintenance and repairs) (ideally the spark plug

connector should be unplugged as well). Always use protective gloves.

• The power tool requires regular maintenance. Only perform maintenance or repairs yourself if the relevant

operations are covered in the operating instructions. All other work should be performed by an authorised

specialist workshop.

• During maintenance of the silencer or when checking that the silencer is firmly positioned, never touch the

silencer if it is still hot – risk of burns! The silencer gives off extremely large amounts of heat.

• Only genuine replacement parts supplied by the manufacturer must be used for any repairs.

• No changes must be made to the power tool, as this could affect the safety of the device and increase the

risk of accident or injury.

1.6 Before starting the tool

Check the tool every time before starting it to make sure that the complete power tool is operationally safe. The

following points should be checked in addition to the points listed in the operating and maintenance

instructions (chapter 11):

• The stop switch must be easy to switch.

• The throttle control must move freely and return automatically to the idle position. If the throttle control is

operated while the choke lever is pressed in then this must cancel any part throttle stop that is set.

• The guide bar must be firmly secured. Always check that the chain has the correct tension and adjust the

tension if required before starting the tool.

• Also check that the ignition cable and spark plug connector are firmly in place. If there is a loose connection

this can result is sparks which could ignite any escaping fuel/air mixture – fire hazard!

If anything is not as it should be, signs of damage are evident, settings are incorrect or the functional integrity of

the unit is compromised, do not start up the power tool. Instead, have it checked by a specialist workshop.

Safety regulations

ENGLISH 6 - 28 -.

1.7 Starting the tool

• When starting the tool, keep a minimum distance of 3 metres to where the tool was refuelled. Never start

the device in an enclosed room.

• Make sure that you have a secure footing on firm ground when starting the tool. Always check that the

ground is level and keep a safe hold of the power tool.

• Perform the start-up routine as described in chapter 8. "Starting the engine / stopping the engine".

• Once the unit has been started, check the idle setting. The cutting blade must be stationary during idling.

• Once it has warmed up, switch the engine off and recheck the chain tension and adjust as required.

1.8 When working with the saw

• The power tool must only be started up if it is fully assembled.

• Work on windfall must only be performed by trained persons.

As soon as the engine is running, it produces toxic exhaust gases which may be colourless and

odourless. Never start up the tool in enclosed spaces. Always make sure that there is sufficient air

exchange if you are working under restricted conditions, such as in a dip or a ditch.

Do not smoke at the place of work or in the close vicinity of the power tool, as this would be an increased

fire hazard.

• Work carefully, deliberately and calmly and do not endanger the safety of others.

- Make sure that visibility and lighting conditions are good.

- Stay within calling distance of others who could help in the event of an emergency.

- Take breaks in good time.

- Be aware of potential sources of danger and take appropriate precautionary measures. Remember that

the use of ear defenders makes it more difficult to hear other sounds. This may also mask sounds

warning of imminent danger or shouts of warning etc.

- Remember that freshly debarked wood is very slippery (bark). Also take care in the wet, when the ground

is slippery, on slopes on uneven terrain.

- Look out for obstacles and hazards that could trip you up, e.g. tree roots, tree stumps and edges. Take

special care when working on slopes. Never work while standing on unstable ground.

- Always hold the power tool firmly with both hands and make sure you have a secure footing on stable

ground at all times.

- Never use the saw above shoulder height and avoid leaning too far forward. Never use the saw while

standing on a ladder, and never climb the tree holding the saw. The only safe way to reach greater

heights is to use a hydraulic lifting cabin.

- Move the chainsaw in such a way that no part of your body would be in the way if the arc of movement of

the saw chain was extended.

- Never touch the ground with the chainsaw while it is running.

- Do not use the saw to prise off or scoop away pieces of wood or other objects.

- Longitudinal cuts should be made at as flat an angle as possible. Special care is required here, as the

bumper spikes cannot engage.

- Be careful when cutting wood which has splintered, as sawn off pieces of wood can be torn off and fly off

at high speeds (risk of injury).

• Switch the engine off if you notice any significant changes in the behaviour of the power tool.

• Never touch the silencer while it is hot – risk of burns. Never set down the hot power tool in dried grass

or on other flammable objects. The silencer gives off extremely large amounts of heat (fire hazard).

• Never work with a defective silencer or without a silencer. You risk damaging your hearing and burning

yourself on the device.

First Aid

A first aid box should always be available on-site. Immediately replace any materials you have used:

Note:

Over exposing persons with circulatory problems to vibrations can lead to damage to their nervous system or

blood vessels. The following systems may occur from vibrations to fingers, hands or the wrists: Numbness,

itching, pain, twinges, changes to the colour of the skin or the skin itself. Seek medical advice if you experience

any of these symptoms.

5. Preparing the equipment for use

5.1 Assembly of the guide bar and chain

The chain brake must be released

when assembling the chain and adjusting the

chain tension [pull back the hand protection

(3) to the front handle (4)].

Notes for new saw chains:

Before installing a new

chain we recommend soaking it in a container (bowl)

with chain oil with anti-fling additives that help the oil

adhere to the chain.

• Undo the retaining nuts on the rail cover (12).

• Take off the rail cover (a).

• When setting up the tool for the first time, remove

the cardboard disc inserted at the factory as

transport protection underneath the rail cover

before installing the guide bar.

• On used saws, clean the rail contact surface and

the oil outlet.

• Use the chain tensioning bolt (13a / 13b) to move

the chain tensioning cam (b) to the left-hand end

stop. .Note:

Each time the guide bar is removed

and installed, adjust the chain

tension cam (b) up

to the l.h. end stop.

• Po Position the guide bar; in the process, the

chain tensioning cam (b) must fully engage in the

designated hole in the guide bar.

• Fit the chain over the sprocket and into the guide

groove of the guide bar.

o The cutting elements of the saw teeth must be on

the upper side of the rail facing towards the tip of

the rail.

o Ensure that the drive links grip correctly between

the teeth of the chain wheel and reversing wheel

at the tip of the guide bar.

• Fit the rail cover, but initially only tighten the

retaining nuts finger tight.

• After correctly adjusting the chain tension (refer to

the next section), tighten the retaining nuts as

described below.

5.2 Adjusting the chain tension

• Loosen the retaining nuts on the rail cover (12), or

if you are assembling the chain, only tighten it

finger-tight.

• Place the rail tip on a suitable wooden support

(e.g. a tree stump) and press the guide bar

upwards slightly as a result.

• Use the chain tensioning bolt (13) to set the

correct chain tension.

o Turn the chain tensioning bolt clockwise to

increase the chain tension or

o anti-clockwise to slacken the chain tension.

• The chain has the correct tension if it makes full

contact with the guide bar but can still be lifted off

the guide bar by hand by around 2 - 4 mm.

(schematic diagram)

• With the rail tip placed on a suitable surface and

the guide bar pressed up slightly, tighten the

retaining nuts with the enclosed combination tool.

Then check the chain tension again.

Always check the chain tension before starting the

device and adjust it as required. You should also

check the chain tension again and adjust it as

required once the power tool has warmed up and

again intermittently while working with the tool – but

make sure the engine is switched off first!

Important hint:

As the chain tightens again slightly when the device

cools off, slacken the chain tension a little once you

have finished work before putting the chainsaw into

storage.

6. Refuelling and adding oil to the chain

lubrication system

The tank caps for the fuel tank and the chain

lubrication oil tank are sealed by means of an O-ring.

Both tank closures should only be tightened finger-

tight, without the use of tools.

6.1 Fuel information

A high performance two-stroke engine

operated with a petrol:oil mixture (petrol + oil =

fuel mixture) or with a special fuel mixture for two-

stroke engines available from specialists powers this

machine.

We recommend the proprietary “Aspen 2-takt”

special fuel mixture. Please observe the special fuel

manufacturer’s instructions.

Information on individual mixing of the fuel mixture

Normal or super unleaded petrol can be used for

individual mixing purposes (minimum octane

number 92 RON).

When using a particularly high quality proprietary 2-

stroke engine oil such as the “SOLO Profi 2T-

Motoröl” which we supply, we recommend an

oil:petrol mixing ratio of 1:50 (2%).

When using other brands of 2-stroke oil we

recommend a mixing ratio of 1:25 (4%).

Only use proprietary 2-stroke engine oil!

Never store fuel mixture longer than 3 - 4 weeks.

10 0,200 0,400

Unsuitable petrol or deviations in the mixing ratio

may lead to serious engine damage!

Avoid direct skin contact with petrol and avoid

inhaling petrol fumes - health hazard!

6.2 Fuelling

While fuelling always follow all safety instructions and

take all safety precautions.

Handle fuel only with the engine turned off.

Carefully clean the area around the filler inlet.

Place the machine with the fuel inlet pointing

upwards. Unscrew the tank lid and fill the fuel

mixture up to the lower edge of the filler neck. Use a

funnel with filter to prevent tank contamination. After

filling the tank replace the tank lid and tighten firmly.

6.3 Chain lubrication

Chainsaw oil with an anti-fling additive that

helps the oil adhere to the chain should be

used for lubrication of the saw chain and guide

bar.

Note: You should generally always add the chain oil

whenever topping up with fuel.

If the saw is used regularly we recommend the use

of biodegradable chainsaw oil.

The bio-chainsaw oil available from SOLO

(order no. 00 83 107, 1 litre) has been

awarded the German blue angel symbol for

eco friendliness (RAL UZ 48).

Biodegradable chainsaw oil only has a limited

lifespan and should be used within a period of 2

years from the printed date of manufacture.

Important: If you are planning to not use the saw for

more than 2 months and are using bio-chainsaw oil

then you will need to drain the oil tank and then add a

small quantity of engine oil (SAE 30). Then run the

chainsaw for a while to ensure that all bio-oil residue

has been flushed out from the tank, oil pickup hose

and cutting device. Fill up with bio-chainsaw oil again

when you are ready to take the saw back into

operation again.

(schematic diagram)

To check the chain lubrication, hold the guide bar

over a light-coloured object (e.g. tree stump) and run

the chainsaw at medium speed (approx. half throttle

setting). A light trace of oil forms on the light-coloured

object.

Important: Never work without chain lubrication.

Check the operation of the chain lubrication system

and the level of the oil in the oil tank every time

before you start work. Never re-use old oil.

Notes for new saw chains:

Before installing a new

chain we recommend soaking it in a container (bowl)

with chain oil with anti-fling additives that help the oil

adhere to the chain. Once the chain has been

installed, do not start to cut wood straight away, but

allow the machine to run at part throttle for a while

until a slight oil trail forms on a lightly coloured

background.

Chain brake ; Starting / Stopping the engine

ENGLISH 12 - 34 -.

7. Chain brake

When the chain brake is activated, it stops the saw

chain in a fraction of a second.

Automatic engagement:

In an emergency, the chain brake engages instantly

in response to the inertia caused by kickback.

Please note that even the highly effective

automatic chain brake cannot offer

complete protection against injury. Always

work with great care and always avoid working

situations which would put you at risk of kickback.

Manual activation:

c To manually activate the chain brake,

press the hand protection (3) forwards

towards the guide bar.

As well as providing a quick response in an

emergency situation, manual activation of the saw

chain brake is intended as a means for immobilising

the tool in all situations in which the operator cannot

knowingly control the position of the guide bar or in

which the risk of unintentional contact between the

saw chain and a foreign body or the user himself

cannot be entirely excluded. This particularly applies

to starting the engine and carrying the tool, e.g. when

assessing an object or the surroundings before

starting cutting work or when walking from one

working area to the next.

In order to avoid excessive wear, the chain brake

should not be applied until the chainsaw has come to

a standstill – except of course in an emergency.

During start-up, once the engine has started the part

throttle setting should be cancelled as soon as

possible by briefly pulling the throttle control. This

ensures that the engine does not have to work

against the blocked chain for too long under part

throttle.

d To release the chain drive (i.e. cancel the

chain brake), pull the hand protection (3) back to

the front handle (4) again

Each time, before commencing your work, check

the function of the chain brake as follows:

• Start the engine (see chapter 8)

• trigger the chain brake at idle speed

• then briefly accelerate to full throttle

• the chain should then not move.

Never operate the chainsaw if it is faulty; instead let

a service workshop check your power tool

immediately

8. Starting / Stopping the engine

Every time you pull the starter cord, observe the

correct position and the safe position of the chainsaw

in accordance with the following chapter 8.2

"Starting".

8.1 Start-up settings

Before starting the engine, apply the chain

brake to immobilise the device.

• Set the stop switch (18) to "I".

• When starting the device for the first time, or after

having completely run down the fuel tank and

refuelled, press the primer (21) several times (at

least 5 x) until fuel can be seen in the plastic

bubble.

• Before pulling the starter handle, press the

decompression valve (22) to make the starting

process easier. (Once the engine has started, the

decompression valve automatically jumps back to

the normal position.)

Cold start:

Pull out the choke (7) [this also activates

the part throttle setting, which can be

seen from the pulled-out part throttle

control pin (8)]

Slowly pull the starter handle until a first

resistance is felt, then pull it through in a

fast and strong motion.

Repeat the starting process until the engine audibly

and briefly starts up (ignites).

Then immediately press the choke back

in again. When the engine is restarted

again it then keeps running at part

throttle (visible from the part throttle

control pin).

With the engine running, briefly operate

the throttle control to cancel the part

throttle setting (the part throttle control

pin jumps back in again). The engine

will then continue to run at idle

speedter.

Warm start:

Start the engine in idle setting with the choke not

pulled out, or start it in

part throttle setting:

by pulling the choke out and pressing it

back in again [the part throttle setting is

activated as a result, which is visible

from the pulled-out part throttle control

pin (8)]

Start the engine until it runs, then briefly operate the

throttle control to cancel the part throttle setting (the

part throttle control pin jumps back in again). The

engine then runs on at idle speed.

8.2 Starting up

Please read the safety instructions before starting up

the device.

(schematic diagram)

Take off the chain guard.

Place the power tool on level ground which is free of

obstructions and make sure that the cutting tool is

not touching anything.

Place one foot in the rear handle to secure the saw

on the ground. Use one hand to firmly hold the saw

by the front handle.

Alternative way to hold the saw while starting it up

(for experienced users only):

(schematic diagram)

Firmly grasp the rear handle between your thighs.

Use one hand to firmly hold the saw by the front

handle.

You must make absolutely sure that there is no

risk of contact between the guide bar and any

part of your body.

The following instructions are intended to extend the

service life of the starter cable and the starter

mechanism:

• To start with, pull the cable carefully until a first

resistance is felt, then pull it through in a fast and

strong motion.

• Always pull the cable in a straight direction.

• Do not allow the cable to chafe on the edge of the

cable eyelet.

• Avoid pulling the cable all the way out – risk of

breaking the cable.

• Always guide the starter handle back to its starting

position – do not just let go and allow it to speed

back by itself.

A damaged starter cable can be replaced by a

specialist.

When the engine is running,

lift up the power tool

and hold it safely with both hands, then briefly

operate the throttle control to cancel the part throttle

setting.

8.3 Engine will not start:

If the engine fails to start after several attempts,

check whether all adjustments described above have

been correctly carried out, particularly that the stop

switch is not in the "0" position. Try starting once

again. The combustion chamber will be flooded, if the

engine still fails to start.

In that case we recommend you proceed as follows:

• Remove the cowl.

• Pull the spark plug cap off the spark plug.

• Remove the spark plug and dry fuel mixture from

the electrodes.

• Move the throttle lever up to full throttle. Pull the

starter handle several times (with removed spark

plug) to clear the combustion chamber.

• Move the throttle lever down to idling position, refit

the spark plug, the plug cap and the cowl.

• Repeat the starting process according to the

starting settings for a warm start.

8.4 Switching the engine off::

Release the throttle control and move the stop switch

to the "0" position.

Always make sure that the cutting tool has come

to a complete standstill before placing the

machine down.

Tip: As it can sometimes happen that, after a

brief/intermediate stop, the starting settings are not

set up correctly before the machine is restarted (in

particular, the stop switch may still be set to "0" and

the chain brake may not have been applied), we

recommend that users should get in the habit of

immediately applying the chain brake whenever the

machine is temporarily switched off and the engine

comes to a complete standstill and of setting the stop

switch back to the "Operating“ position.

As a general rule, you should always check the

starting settings before every start.

Switching the engine off in the event of a malfunction:

If – due to a malfunction of the stop switch – it is not

possible to switch the engine off, you can also close

the choke flap

(choke pulled out) to bring the

engine to a standstill. In this case do not restart the

tool – have it checked out immediately by a specialist

workshop instead!

Hazards caused by kickback

ENGLISH 14 - 36 -.

9. Hazards caused by kickback

When working with the chainsaw,

careless or incorrect working methods

can cause a dangerous situation which is

referred to as "kickback". Kickback forces can occur

when the running saw chain comes into contact with

solid objects or if the saw chain suddenly gets stuck

in the cut. In the process, the chainsaw is

accelerated violently and uncontrollably.

Depending on the contact point of the running saw

chain, the forces acting on the chainsaw are directed

as follows, resulting in the corresponding

acceleration of the tool:

1. Contact point at the tip of the guide bar:

(schematic

diagram)

Danger: The guide bar is kicked up suddenly

and quickly. As the user is holding the

chainsaw by the handles, this results in a rotational

acceleration of the chainsaw, during which the guide

bar is accelerated towards the head of the operator.

Although this rotational acceleration instantly

activates the chain brake, the magnitude of the

acceleration and the uncontrolled response of the

operator can result in serious accidents.

2. Contact point in the upper part of the guide bar:

Danger: The chainsaw is kicked suddenly in the

direction of the operator. The magnitude of the

acceleration and the uncontrolled response of the

operator can result in serious accidents.

Experienced users can perform a so-called "backhand

cut". This can only be done by anticipating the sudden

acceleration of the tool and supporting the chainsaw in

a rearward direction with your thigh before positioning

the tool for the cut and while performing the cut.

Inexperienced users must not use the

"backhand cut"!

Contact point in the lower part of the guide bar

(bumper spikes (26) as the point at which the

chainsaw is positioned on the cutting object):

Safe application: The chainsaw is pulled towards

the object being sawn. As the bumper spikes (26) on

the engine housing are positioned on the object being

sawn, the chainsaw cannot be accelerated away. The

operator is able to control the tool safely.

The following general guidelines should be followed

in order to avoid kickback:

• Always hold the chainsaw firmly with both hands.

Position your right hand on the rear handle

and your left handle on the front handle.

• Before positioning the saw for the cut, apply the

throttle and, with the saw chain running, start the

cut on the underside of the guide bar as close as

possible to the engine housing.

• Never cut more than one branch at a time. When

removing branches, bear in mind that other

branches may inadvertently come into contact with

the saw chain. When cutting to length, look out for

other trunks which may be close nearby.

• Special care is required when continuing cuts

which have already been started.

• Carefully watch the guide bar during the cut.

• Look out for forces which could compress the cut

gap and cause the saw chain to become trapped,

particularly on objects which are under tension.

• Always follow the correct procedure for sharpening

the saw chain. In the process, pay particular

attention to the correct height of the depth limiter.

Professional users can use special working

techniques which must only be carried out by

experienced users. We recommend that anyone who

wishes to safely learn about the more difficult

techniques which are not described here should

attend a special course (e.g. at specialist forestry

training centre).

10. Using the chainsaw

10.1 Application areas

The chainsaw must only be used to cut wood and

objects made of wood.

Any loose wooden objects must be safely secured

(e.g. on a sawhorse). When cutting down overgrown

trees and branches please refer also to the notes on

cutting down trees and removing branches.

The chainsaw must not be used for any other

purpose, for example to cut plastics or metals.

10.2 Initial use/ start-up behaviour

When switching on the motor for the first five times

prior to commencing work, first operate for a short

time in the mid-speed range without any load until

the engine has warmed up a little.

10.3 Chain lubrication adjusting screw

Your new chainsaw is equipped with an automatic

chain lubrication system which automatically stops

the delivery of oil when the chainsaw is idling (Eco-

Matic). When the throttle is operated and the saw

chain is driven again the chain lubrication

automatically restarts.

To adjust the amount of oil delivered by this system

during operation, the control screw (Fig. 1d - 28) on

the underside of the chainsaw can be adjusted

approximately ± 120° from plus(+) to minus(-).

As a guideline, we recommend that if you are using

38cm cutting gear to cut wood which is still moist

then the mid-position between (+) and (-) is a good

starting point. Adjust the controls to deliver slightly

more oil if you are cutting dry wood.

10.4 Sawing

Always follow the safety instructions when

performing any kind of work with the saw. Always

hold the chainsaw firmly with both hands. Position

your right hand on the rear handle and your left

handle on the front handle.

Cutting to length:

Make sure that you have a secure footing.

Clean the area which is to be cut of any foreign

bodies like sand, stones, nails etc. Foreign bodies

can cause dangerous kickback.

Loose wooden objects must be

firmly secured, ideally with a

sawhorse. The wood must nut be

held in place with a foot or by

another person. Round timber must

be secured so that they cannot

rotate.

Apply full throttle and move the chainsaw close to the

cutting point, position and press the bumper spikes

onto the object you wish to saw (a), then – and not

before – use a pivoting movement (around the point

at which the bumper spikes have been positioned) to

move the guide bar downwards (b) and start the cut.

Important note on cutting branches which are under

tension (e.g. in the forest):

• Always make the first cut on the compression side

c, but be careful as there is a risk of pinching.

• Then proceed carefully and make a cut at the

tension side.

• On thick trunks which are under a lot of tension

offset the cut to one side.

>c= Î Pressure side

=d> Î Tension side

Trunk under tension on the

upper side.

Danger: The tree will spring

back in an upward direction.

Trunk under tension on the

underside:

Danger: The tree will spring

back in a downward direction

Thick trunks and high tension:

Danger: The tree will spring

back suddenly and with

considerable force. Also watch

out for the root clump tipping

back.

Trunk under lateral tension:

Danger: The tree will spring

back to one side

Note: Always stand on the compression side if the

tree is under lateral tension.

If the saw becomes pinched in the cut, stop the

engine and lift the trunk with a bar or other lever, or

change its position to open up the cutting gap.

Fig. 13

Using the chainsaw

ENGLISH 16 - 38 -.

Removing branches:

Do not cut through free-hanging branches from

underneath.

Do not remove branches while standing on the trunk.

Remove any obstructing branches before you start

sawing.

If you change your standing point, remember that the

guide bar must always be on the side of the trunk

facing away from your body.

Always keep an eye on tree and branch movement –

plan ahead and proceed with care!

When removing branches on thick hardwood trees,

follow the correct procedure described below to

prevent the chainsaw from becoming pinched:

1. Remove any obstructing

branches.

2. Cut off any branches

which are creating tension.

3. Cut off the main branch

(note which side is the

compression side and which the tension side).

If it is important that the wood does not tear, make a

relieving cut.

Start this cut on the

compression side

c, then

finish the cut from the

tension side

The remainder of the

branch which is left

standing is now no longer

under tension and can be

cut off close to the trunk

Felling:

Felling trees is dangerous and requires training.

If you are a novice then you must not fell any

trees. You can attend a training course to learn how

to fell trees.

Before felling a tree, make sure that:

• No persons other than those involved in the felling

of the tree are in the felling area.

• Everybody involved in the felling has an

unobstructed path of escape. The path of escape

should be opposite to the planned direction of the

fall of the tree at an angle of around 45°.

• The nearest working area should be at least 2½

tree lengths away.

Before felling a tree you need to carefully check the

direction of fall and make sure that no persons,

animals or objects are within 2½ tree lengths.

Then consider the general condition of the tree:

Hanging direction – loose or dry branches – height of

the tree – natural overhang – is the tree diseased?

You also need to take into account the wind speed

and wind direction. Do not fell a tree under heavy,

gusting winds.

The foot of the trunk must be free of all foreign

objects, roots, undergrowth and branches.

Ensure that you have a secure footing and remove

any objects which could cause you to trip.

Cutting into the buttress roots:

Start with the largest

buttress root first.

Make a vertical cut into the

root

c, followed by a

horizontal cut

Never cut into diseased trunks before felling them.

Note: Leave the buttress root intact as a wedge on

the side opposite the direction of fall.

Fig. 14

Using the chainsaw ; Operating and maintenance information

- 39 - ENGLISH 17

Making the felling notch:

The felling notch determines the direction in which

the tree falls and helps to control the fall. It is made

perpendicular to the fall direction with a cut through

1/5 - 1/3 of the trunk diameter. The cut should

preferably be made close to the ground.

c Start with the upper cut (roof of the felling notch).

d Then make the lower cut (bottom of the felling

notch). The lower cut should meet the upper cut

precisely.

Check the direction of fall.

If the felling notch needs to be corrected, always

re-cut it across the full width. In exceptional

cases it is also possible to slope the lower cut

upwards to obtain a more open felling notch. If

the tree is situated on a slope this gives longer

control over the fall.

e The felling cut is made higher f than the bottom

of the felling notch

d. This cut must be exactly

horizontal. In front of the felling notch around

1/10 of the trunk diameter needs to be left as a

hinge

g The hinge must not be cut through, as this could

result in loss of control over the fall of the tree.

Wedges need to be positioned in good time. The

felling cut must only be secured with plastic or

aluminium wedges, and steel wedges must never be

used.

During felling, always keep to the side of the tree.

When walking back after the felling cut has been

made, watch out for falling branches.

When working on a slope, the operator of the saw

should stand above or to the side of the trunk or tree

being worked on.

Stand back when the tree falls. Observe the crown of

the tree.

Wait for the crown to swing out.

Do not continue work under branches or trees which

have become caught.

After work Î slacken the chain tension

11. Operating and maintenance information

With modern equipment and safety-relevant

components, maintenance and repairs must only be

carried out by persons with suitable specialist

qualifications in a workshop equipped with the

necessary special tool and testing equipment. As a

result, the manufacturer recommends that all work

which is not described in these operating instructions

should be performed by a specialist workshop. The

experts have access to the training, experience and

equipment which is required in order to provide you

with the most cost-effective solution. An expert can

also offer invaluable advice.

Always follow all of the safety instructions when

performing maintenance work.

After the device has been run in for around 5

operating hours, all accessible nuts, bolts and screws

(except the carburettor adjusting screws) should be

checked for tightness and retightened as required.

It is best to store the device in a dry and safe location

with a full fuel tank. There must not be any naked

flames or similar nearby. If you plan to not use the

chainsaw for a longer period (i.e. more than four

weeks), please refer to the information in chapter

11.1 "Shutdown and storage”.

11.1 Shutdown and storage

The chainsaw should be thoroughly cleaned and

checked for damage after every use. The most

important areas are the chain brake, the cooling air

intake area, the cylinder cooling fins and the air filter.

Only use the eco-friendly cleaning agents available

from a specialist retailer. Do not use fuel to clean the

chainsaw.

The chainsaw should be stored in a dry room and

fitted with a chain guard. There must be no naked

flames or similar in the vicinity. Measures must be

taken to prevent unauthorised use of the chainsaw,

particularly by children.

If you plan to stop using the saw for more than four

weeks then you should also drain the fuel tank and

the chain lubrication oil tank in a well vented area and

clean them. Start the engine with the fuel tank empty

and run it until the carburettor is empty and the

engine goes out. Otherwise oil residue from the fuel

mixture could block the carburettor nozzles and make

subsequent starts more difficult.

Important: If you are using bio-chainsaw oil and

planning to stop using the chainsaw for at least 2

months then you should run the chainsaw for a while

with the oil tank filled with engine oil (SAE 30), so that

all residue of the bio-oil is flushed from the tank, oil

pickup hose and cutting device.

Fig. 15

Operating and maintenance information

ENGLISH 18 - 40 -.

11.2 Maintenance and care of the cutting gear

Saw chain:

Just like any other cutting tool, the saw chain is

subject to natural wear. Your chainsaw will only be

able to deliver its full potential if the saw chain is

correctly sharpened. Every saw chain is matched to

the relevant chainsaw type in terms of its form,

cutting performance and design. Only use the

genuine SOLO saw chain which is approved for your

chainsaw / guide bar type.

Permissible cutting gear and the corresponding

cutting lengths Î refer to the last two inside pages of

this operating manual ( - 258 -.)

Sharpening the saw chain:

A special round chain file with the correct diameter

should be used for sharpening. Normal round files

are not suitable.

A file holder makes

guidance of the file

easier, as it has

markings for the

correct sharpening

angle (align the

markings parallel to the

saw chain) and limits

the penetration depth

(4/5 of the file

diameter)

Position the file holder on the roof of the tooth. The

file should only engage during the forward stroke. Lift

the file off when moving it back.

The shortest cutting tooth is

sharpened first. The length of

this tooth is then the target

size for all the other teeth on

the saw chain. All of the cutting elements must have

the same length.

To start with, file all of the cutting elements on one

side from the inside outwards, then file all of the

cutting elements on the other side.

Always fully file out any damage from the side plate

or the roof of the tooth.

Correction of the depth limiter:

The distance b between the

depth limiter (round nose) and

the cutting edge defines the

thickness of the chips. The

best cutting results are

obtained with the prescribed

depth limiter spacing, which

should be checked every time

the saw chain is sharpened.

Lay the depth limiter gauge on

the cutting element. If the

depth limiter protrudes, file off

the protruding part with a flat

file.

Round off the front edge of

the depth limiter. The original

shape must be restored.

CAUTION: If the spacing is too large then there

is a greater risk of kickback.

For your safety: If you would like to pull the chain

through while filing, pull the chain forwards with a

screwdriver towards the tip of the rail. This will reduce

the risk of slipping.

Sprocket

Before you can fit a new saw chain you must check

the condition of the sprocket. Worn sprockets will

damage your new saw chain. If necessary, replace

the sprocket with the new chain. Grease the bearing

with lithium-based grease whenever the sprocket is

replaced.

Tip: We recommend the use of two saw chains per

sprocket, and that both chains should be replaced as

frequently as possible so that all of the components

wear evenly. Once a certain wear limit is reached,

replace all of the parts together again.

To replace the chain

wheel (after dismantling

the guide bar cover and

the guide bar with chain),

push the chain wheel with

its washer down slightly

and lift off the locking ring

with a small screwdriver.

To refit the locking ring after

fitting the new chain wheel

push the chain wheel, with

its washer, down again

slightly. It is best to use flat

pliers when refitting the

retaining ring.

Operating and maintenance information

- 41 - ENGLISH 19

Guide bar:

The guide bar of your

chainsaw requires just as

much care as the saw

chain. The running

surfaces must be flat and

level, and the groove must

not be widened.

In order to prevent one-sided wearing of the guide

bar, we recommend that the guide bar be reversed

whenever the chain is sharpened.

On guide bars with a guide

sprocket, the bearing of the

guide sprocket should

preferably be lubricated with

ball bearing grease (through

the lubricating hole on the side with a grease gun)

every time the chainsaw is refuelled. Rotate the

guide sprocket while doing this.

Important: The guide bars are only designed to

guide the saw chain and must not be used as a

levering tool. Any twisting or turning or use of the

guide bar to gain leverage in the wood shortens the

service life of the guide bars.

11.3 Air Filter Maintenance

Contaminated air filters cause a reduction in engine

performance and increase fuel consumption with

more pollutants in the exhaust gas. Engines are less

likely to start readily with a contaminated air filter.

When using the power tool all day, clean the air filter

daily; under very dusty conditions, even several

times a day.

Carry out the following maintenance jobs regularly.

Taking off the cowl:

• Release the three fastening

clips (16), preferably by

applying a screwdriver in a

twisting motion.

• Lift off the cowl (5) upwards.

Cleaning the air filter

• Important: Pull out the choke (7).

• Push both clamping brackets (a) with a screwdriver

off the filter casing.

• Remove the upper filter part (b).

• Simply tapping or careful blowing through the filter

is the best method for cleaning. When using

compressed air, wear eye protection (e.g. safety

goggles), and hold the compressed air stream not

too closely against the air filter.

• In case of severe contamination, the air filter can

be cleaned with non-flammable cleaning fluid

(warm soapy solution).

NB: The air filter must be absolutely dry before

it is reinstalled.

• Clean the lower casing part (c) up to the closed

choke damper with a paint brush or remove dirt

and dust particles carefully by blowing them out of

the casing.

• After cleaning, carefully position the dry filter

element (b) onto the lower casing part (c). There

must not be any open gap around the filter

element.

• Close the air filter securely with both clamping

brackets (a).

The corresponding parts should be replaced

immediately if the filter material is damaged. No

warranty claims can be accepted for engine damage

arising as a result of inadequate care.

Fitting the cowl

For ease of installation press the hand

protection (3) forwards (chain brake is

applied).

• Fit the cowl, making sure it goes on straight.

• Insert the cowl in the slot on the main housing,

making sure that it fits properly in the slot all the

way around.

Once the cowl is correctly seated, secure the cowl

again using the three fastening clips (16).

ENGLISH 20 - 42 -.

11.4 Carburettor settings

The carburettor is preset to the optimum settings for

the device at the factory. Depending on the particular

location where the chainsaw is used (mountains, flat

country) it may be necessary to adjust the idling

settings via the idle stop screw "T" (24).

When the idling settings are correct the engine

should run smoothly at idle without the saw chain

being driven. Corrective adjustments to the average

idle speed indicated in the technical data can be

made as follows via the idle stop screw "T" – ideally

with the aid of a tachometer:

• If the idle speed is too high (particularly if the saw

chain is already driven without the throttle being

operated), slightly open up the idle stop screw

"T" by turning it anti-clockwise.

• If the idle speed is too low (i.e. the engine keeps

stopping at idle), slightly close the idle stop screw

"T" by turning it clockwise until the engine runs

evenly.

The saw chain must never be driven while the

engine is idling.

If the idling speed cannot be set correctly with the

idling end-stop screw "T", request an authorised

service centre to tune the carburettor.

The adjusting screws for the idling mixture "L"

and the full-load mixture "H" (25) must only be

adjusted by an authorised workshop.

The following instructions are for authorised

service shops

D-CUT carburettors:

Use the D-CUT carburettor key to adjust the idle

mixture screw "L" and the full load mixture screw "H".

Carburettors with limiter caps:

The regulating screws for idle mixture and full load

mixture can only be adjusted in a limited range.

Clean the air filter before adjusting the low speed

screw!

Let the engine run warm before adjusting the engine

speed.

The carburettor is tuned for optimum engine

performance. Use a rev counter to tune the

carburettor correctly!

Do not adjust the engine to a higher speed.

Excessive engine speed can lead to major engine

damage!

11.5 Vibration damping

If you find that vibrations on the handles worsen

significantly with time in comparison to when the

chainsaw was new, check the damping elements

(rubber-bonded metal mountings) for damage and

replace them as required.

Working with the chainsaw while the

vibration damping system is not working

properly can cause health problems.

11.6 Maintenance of the chain brake

Check for ease of movement and correct operation on a

daily basis. Remove any resin, sawdust and dirt.

Visible joints and bearings should be lubricated with

grease or temperature-resistant engine oil.

• Chain brake function test (chapter 7.).

11.7 Spark plug information

The spark plug should be regularly checked every 50

operating hours.

• Take off the cowl from the chainsaw.

• Disconnect the spark plug connector which is

located underneath.

• Unscrew the spark plug and dry it thoroughly.

In the event of severe burn-off of the electrodes the

spark plug should be replaced immediately, otherwise

every 100 hours.

The engine must not be moved if the spark plug is

removed or the ignition cable is disconnected.

Otherwise there is a risk that sparks could form which

might cause a fire.

Interference-suppressed replacement spark plugs

(calorific value: 200) are available for example under

the following trade names:

BOSCH WSR6F

CHAMPION RCJ-6Y or equivalent.

The prescribed electrode gap is 0.5 mm.

Before starting work, check the ignition cable to make

sure the connections are in good working order and

the insulation is intact.

• Screw the spark plug back in again.

• Always press the spark plug connector firmly onto

the spark plug.

• Refit the cowl to the chainsaw.

11.8 Replacing the fuel filter

We recommend having the fuel filter changed

annually by a specialised service centre.

A trained mechanic can carefully remove the fuel filter

via a wire loop through the fuel tank filler. Ensure that

the thicker part of the fuel hose on the tank wall is not

drawn into the fuel tank.
