SAFETY WARNINGS

General power tool safety warnings

WARNING:

Read all safety warnings, instruc-

tions, illustrations and specications provided with this

power tool. Failure to follow all instructions listed below

may result in electric shock, re and/or serious injury.

Save all warnings and instruc-

tions for future reference.

The term "power tool" in the warnings refers to your

mains-operated (corded) power tool or battery-operated

(cordless) power tool.

Cordless grinder safety warnings

Safety warnings common for grinding, sanding,

wire brushing, or cutting-o operations:

1.

This power tool is intended to function as a

grinder, sander, wire brush, or cut-o tool. Read

all safety warnings, instructions, illustrations

and specications provided with this power tool.

Failure to follow all instructions listed below may

result in electric shock, re and/or serious injury.

2.

Operations such as polishing or hole cutting

are not to be performed with this power tool.

Operations for which the power tool was not designed

may create a hazard and cause personal injury.

3. Do not convert this power tool to operate in

a way which is not specically designed and

specied by the tool manufacturer. Such a con-

version may result in a loss of control and cause

serious personal injury.

4. Do not use accessories which are not spe-

cically designed and specied by the tool

manufacturer. Just because the accessory can

be attached to your power tool, it does not assure

safe operation.

12 ENGLISH

5. The rated speed of the accessory must be at

least equal to the maximum speed marked on

the power tool. Accessories running faster than

their rated speed can break and y apart.

6. The outside diameter and the thickness of your

accessory must be within the capacity rating

of your power tool. Incorrectly sized accessories

cannot be adequately guarded or controlled.

7. The dimensions of the accessory mounting

must t the dimensions of the mounting hard-

ware of the power tool. Accessories that do not

match the mounting hardware of the power tool

will run out of balance, vibrate excessively and

may cause loss of control.

8. Do not use a damaged accessory. Before each

use inspect the accessory such as abrasive

wheels for chips and cracks, backing pad for

cracks, tear or excess wear, wire brush for

loose or cracked wires. If power tool or acces-

sory is dropped, inspect for damage or install

an undamaged accessory. After inspecting and

installing an accessory, position yourself and

bystanders away from the plane of the rotating

accessory and run the power tool at maximum

no-load speed for one minute. Damaged acces-

sories will normally break apart during this test

time.

9. Wear personal protective equipment.

Depending on application, use face shield,

safety goggles or safety glasses. As appro-

priate, wear dust mask, hearing protectors,

gloves and workshop apron capable of stop-

ping small abrasive or workpiece fragments.

The eye protection must be capable of stopping

ying debris generated by various applications.

The dust mask or respirator must be capable

of ltrating particles generated by the particular

application. Prolonged exposure to high intensity

noise may cause hearing loss.

10. Keep bystanders a safe distance away from

work area. Anyone entering the work area

must wear personal protective equipment.

Fragments of workpiece or of a broken accessory

may y away and cause injury beyond immediate

area of operation.

11. Hold the power tool by insulated gripping

surfaces only, when performing an operation

where the cutting tool may contact hidden

wiring. Contact with a "live" wire will also make

exposed metal parts of the power tool "live" and

could give the operator an electric shock.

12. Never lay the power tool down until the acces-

sory has come to a complete stop. The spinning

accessory may grab the surface and pull the

power tool out of your control.

13. Do not run the power tool while carrying it at

your side. Accidental contact with the spinning

accessory could snag your clothing, pulling the

accessory into your body.

14. Regularly clean the power tool’s air vents. The

motor’s fan will draw the dust inside the housing

and excessive accumulation of powdered metal

may cause electrical hazards.

15. Do not operate the power tool near ammable

materials. Sparks could ignite these materials.

16. Do not use accessories that require liquid

coolants. Using water or other liquid coolants

may result in electrocution or shock.

Kickback and related warnings:

Kickback is a sudden reaction to a pinched or snagged

rotating wheel, backing pad, brush or any other acces-

sory. Pinching or snagging causes rapid stalling of the

rotating accessory which in turn causes the uncon-

trolled power tool to be forced in the direction opposite

of the accessory’s rotation at the point of the binding.

For example, if an abrasive wheel is snagged or

pinched by the workpiece, the edge of the wheel that is

entering into the pinch point can dig into the surface of

the material causing the wheel to climb out or kick out.

The wheel may either jump toward or away from the

operator, depending on direction of the wheel’s move-

ment at the point of pinching. Abrasive wheels may also

break under these conditions.

Kickback is the result of power tool misuse and/or

incorrect operating procedures or conditions and can be

avoided by taking proper precautions as given below.

1. Maintain a rm grip with both hands on the

power tool and position your body and arms

to allow you to resist kickback forces. Always

use auxiliary handle, if provided, for maxi-

mum control over kickback or torque reaction

during start-up. The operator can control torque

reactions or kickback forces, if proper precautions

are taken.

2. Never place your hand near the rotating acces-

sory. Accessory may kickback over your hand.

3. Do not position your body in the area where

power tool will move if kickback occurs.

Kickback will propel the tool in direction opposite

to the wheel’s movement at the point of snagging.

4. Use special care when working corners, sharp

edges, etc. Avoid bouncing and snagging the

accessory. Corners, sharp edges or bouncing

have a tendency to snag the rotating accessory

and cause loss of control or kickback.

5. Do not attach a saw chain woodcarving blade,

segmented diamond wheel with a peripheral

gap greater than 10 mm or toothed saw blade.

Such blades create frequent kickback and loss of

control.

Safety warnings specic for grinding and cut-

ting-o operations:

1. Use only wheel types that are specied

for your power tool and the specic guard

designed for the selected wheel. Wheels for

which the power tool was not designed cannot be

adequately guarded and are unsafe.

2. The grinding surface of centre depressed

wheels must be mounted below the plane of

the guard lip. An improperly mounted wheel that

projects through the plane of the guard lip cannot

be adequately protected.

3. The guard must be securely attached to the

power tool and positioned for maximum safety,

so the least amount of wheel is exposed

towards the operator. The guard helps to protect

the operator from broken wheel fragments, acci-

dental contact with wheel and sparks that could

ignite clothing.

13 ENGLISH

4.

Wheels must be used only for specied applica-

tions. For example: do not grind with the side of

cut-o wheel. Abrasive cut-o wheels are intended

for peripheral grinding, side forces applied to these

wheels may cause them to shatter.

5. Always use undamaged wheel anges that are

of correct size and shape for your selected

wheel. Proper wheel anges support the wheel

thus reducing the possibility of wheel breakage.

Flanges for cut-o wheels may be dierent from

grinding wheel anges.

6. Do not use worn down wheels from larger

power tools. A wheel intended for larger power

tool is not suitable for the higher speed of a

smaller tool and may burst.

7. When using dual purpose wheels always use

the correct guard for the application being

performed. Failure to use the correct guard may

not provide the desired level of guarding, which

could lead to serious injury.

Additional safety warnings specic for cutting-o

operations:

1. Do not “jam” the cut-o wheel or apply exces-

sive pressure. Do not attempt to make an

excessive depth of cut. Overstressing the wheel

increases the loading and susceptibility to twisting

or binding of the wheel in the cut and the possibil-

ity of kickback or wheel breakage.

2. Do not position your body in line with and

behind the rotating wheel. When the wheel, at

the point of operation, is moving away from your

body, the possible kickback may propel the spin-

ning wheel and the power tool directly at you.

3. When the wheel is binding or when interrupt-

ing a cut for any reason, switch o the power

tool and hold it motionless until the wheel

comes to a complete stop. Never attempt to

remove the cut-o wheel from the cut while

the wheel is in motion otherwise kickback may

occur. Investigate and take corrective action to

eliminate the cause of wheel binding.

4. Do not restart the cutting operation in the

workpiece. Let the wheel reach full speed and

carefully re-enter the cut. The wheel may bind,

walk up or kickback if the power tool is restarted in

the workpiece.

5. Support panels or any oversized workpiece to

minimize the risk of wheel pinching and kick-

back. Large workpieces tend to sag under their

own weight. Supports must be placed under the

workpiece near the line of cut and near the edge

of the workpiece on both sides of the wheel.

6. Use extra caution when making a “pocket cut”

into existing walls or other blind areas. The

protruding wheel may cut gas or water pipes, elec-

trical wiring or objects that can cause kickback.

7. Do not attempt to do curved cutting.

Overstressing the wheel increases the loading and

susceptibility to twisting or binding of the wheel

in the cut and the possibility of kickback or wheel

breakage, which can lead to serious injury.

8. Before using a segmented diamond wheel,

make sure that the diamond wheel has the

peripheral gap between segments of 10 mm or

less, only with a negative rake angle.

Safety warnings specic for sanding operations:

1. Use proper sized sanding disc paper. Follow

manufacturers recommendations, when

selecting sanding paper. Larger sanding paper

extending too far beyond the sanding pad pres-

ents a laceration hazard and may cause snagging,

tearing of the disc or kickback.

Safety warnings specic for wire brushing

operations:

1. Be aware that wire bristles are thrown by the

brush even during ordinary operation. Do not

overstress the wires by applying excessive

load to the brush. The wire bristles can easily

penetrate light clothing and/or skin.

2. If the use of a guard is specied for wire

brushing, do not allow any interference of the

wire wheel or brush with the guard. Wire wheel

or brush may expand in diameter due to work load

and centrifugal forces.

Additional Safety Warnings:

1. When using depressed centre grinding wheels,

be sure to use only berglass-reinforced

wheels.

2. NEVER USE Stone Cup type wheels with this

grinder. This grinder is not designed for these

types of wheels and the use of such a product

may result in serious personal injury.

3. Be careful not to damage the X-LOCK holder.

Damage to the parts could result in wheel

breakage.

4. Make sure the wheel is not contacting the

workpiece before the switch is turned on.

5. Before using the tool on an actual workpiece,

let it run for a while. Watch for vibration or

wobbling that could indicate poor installation

or a poorly balanced wheel.

6. Use the specied surface of the wheel to per-

form the grinding.

7. Do not leave the tool running. Operate the tool

only when hand-held.

8. Do not touch the workpiece immediately after

operation; it may be extremely hot and could

burn your skin.

9. Do not touch accessories immediately after

operation; it may be extremely hot and could

burn your skin.

10. Observe the instructions of the manufacturer

for correct mounting and use of wheels.

Handle and store wheels with care.

11. Do not use separate reducing bushings or

adaptors to adapt large hole abrasive wheels.

12.

Check that the workpiece is properly supported.

13. Pay attention that the wheel continues to

rotate after the tool is switched o.

14. If working place is extremely hot and humid,

or badly polluted by conductive dust, use a

short-circuit breaker (30 mA) to assure opera-

tor safety.

15. Do not use the tool on any materials contain-

ing asbestos.

16. When use cut-o wheel, always work with

the dust collecting wheel guard if required by

domestic regulation.

14 ENGLISH

17. Cutting discs must not be subjected to any

lateral pressure.

18. Do not use cloth work gloves during operation.

Fibers from cloth gloves may enter the tool, which

causes tool breakage.

19.

Before operation, make sure that there is no

buried object such as electric pipe, water pipe or

gas pipe in the workpiece. Otherwise, it may cause

an electric shock, electrical leakage or gas leak.

SAVE THESE INSTRUCTIONS.

WARNING: DO NOT let comfort or familiarity

with product (gained from repeated use) replace

strict adherence to safety rules for the subject

product. MISUSE or failure to follow the safety

rules stated in this instruction manual may cause

serious personal injury.

OPERATION

WARNING: It should never be necessary to

force the tool. The weight of the tool applies ade-

quate pressure. Forcing and excessive pressure

could cause dangerous wheel breakage.

WARNING: ALWAYS replace wheel if tool is

dropped while grinding.

WARNING: NEVER hit the workpiece with the

wheel.

WARNING: Avoid bouncing and snagging

the wheel, especially when working corners,

sharp edges etc. This can cause loss of control and

kickback.

WARNING: NEVER use tool with wood cutting

blades and other saw blades. Such blades when

used on a grinder frequently kick and cause loss of

control leading to personal injury.

WARNING: Never actuate the release lever of

the X-LOCK holder during operation. The X-LOCK

wheel comes o from the tool and may cause serious

injury.

WARNING: Make sure that the X-LOCK wheel

is xed rmly.

CAUTION: Never switch on the tool when it

is in contact with the workpiece, it may cause an

injury to operator.

CAUTION: Always wear safety goggles or a

face shield during operation.

CAUTION: After operation, always switch o

the tool and wait until the wheel has come to a

complete stop before putting the tool down.

CAUTION: ALWAYS hold the tool rmly with

one hand on housing and the other on the side

grip (handle).

Grinding and sanding operation

► Fig.20

Turn the tool on and then apply the wheel or disc to the

workpiece.

In general, keep the edge of the wheel or disc at an

angle of about 15° to the workpiece surface.

During the break-in period with a new wheel, do not

work the grinder in forward direction or it may cut into

the workpiece. Once the edge of the wheel has been

rounded o by use, the wheel may be worked in both

forward and backward direction.

Operation with abrasive cut-o /

diamond wheel

Optional accessory

WARNING: Do not "jam" the wheel or apply

excessive pressure. Do not attempt to make an

excessive depth of cut. Overstressing the wheel

increases the loading and susceptibility to twisting

or binding of the wheel in the cut and the possibility

of kickback, wheel breakage and overheating of the

motor may occur.

WARNING: Do not start the cutting operation

in the workpiece. Let the wheel reach full speed

and carefully enter into the cut moving the tool

forward over the workpiece surface. The wheel

may bind, walk up or kickback if the power tool is

started in the workpiece.

WARNING: During cutting operations, never

change the angle of the wheel. Placing side pres-

sure on the cut-o wheel (as in grinding) will cause

the wheel to crack and break, causing serious per-

sonal injury.

WARNING: A diamond wheel shall be oper-

ated perpendicular to the material being cut.
