6 Installation and commissioning

The machine must only be installed and commissioned by qualified personnel!

All relevant safety regulations must be strictly adhered to!

If the machine is delivered without a table, be sure to use a stand and table top that can hold the

weight of the machine with its motor.

It is very important to ensure that the stand of the machine is firm and steady, also during

sewing.

6.01 Installation

The site where the machine is installed must be provided with suitable connections for electric

current.

It must be ensured that the standing surface of the machine site is firm and horizontal, and that

sufficient lighting is provided for.

For packing and transportation reasons the table top is in the lowered position. The

table height is adjusted as described below.

6.01.01 Adusting the table height

● Loosen screws 1and 2 and set the table height as required.

● Firmly tighten screw 1.

● Set the required pedal position and tighten screw 2

6.02.01 Fitting the reel stand

l Fit the reel stand as shown in Fig.

● Afterwards insert the stand in the hole of the table

top and secure it with the nuts provided.

6.02.02 Fitting the tilt lock

6.02.03 Fitting the machine cover

6.02.04 Mounting the flange motor to the bearing plate

6.02.05 Mounting the flange motor to the machine

www.garudan.cz

6.02.06

6.02.07 Mounting the belt guard of the flange motor

● In this position fit toofhed belt 1.

● Swing the bearing plate 2 of the motor,so that the toothed belt is tensioned.

● In this position tighten screws 3.

6.02.08 Connecting the safety switch

6.01 Commissioning

6.02

● Check the machine, particularly the electrical wriring for any damage.

● When the machine is running, the balance wheel must turn towards the operator.If it does

not, the motor connection must be changed by a mechanic.

● Machines with pneumatic equipment must be connected to the compressed air supply.

The pressure gauge should indicate a pressure of 6 bar. If necessary, adjust to the

correct setting (see Chapter 11.07 Checking adjusting the air pressure).

●Connect plug 1 of safety switch 2 as

shown in Fig.

When the sewing head is

tilted back,the safety switch

prevents the machine starting

when the main switch is on.
