GB-6

• After use, lay the chainsaw horizontally on some absor-

bing surface. The oil spread on the blade, chain and

drive may lead to some further dripping of oil.

3.2. Assembling the blade and chain (Fig. 3-4)

CAUTION ! Risk of injury ! Always

use safety

gloves when assembling the chain !

For assembling the bar and chain with this chain saw

no tools are required !

• Put the chain saw on a stable rest.

• Loosen the T-screw (7) turning it clockwise.

• Remove the gear cover (8).

• Put the chain on the bar considering the running

direction of the chain. The cutting teeth on the upper

side of the bar must point in forward direction (see

Fig. 4).

• Put the free end of the chain over the chain driving

wheel (B).

• Place the bar such that the long hole in the bar is

placed exactly on the guiding element in the bar seat.

• Take care that the chain tensioning bolt (A) is seated

exactly in the small opening in the bar (Fig. 3). It must

be visible through the opening. If necessary, adjust the

knurling wheel of the chain tensioning device (16) in

both directions until the chain tensioning bolt is seated

in the opening in the bar.

• Check whether all chain links are seated exactly in the

bar’s groove and the chain is lead around the chain

driving wheel correctly.

• Put the gear cover (8) back on and push it in place.

• Moderately tighten the T-screw (7) by turning it clock-

wise.

• Tension the chain. To do so turn the knurling wheel

upwards (+ direction of arrow). The chain should be

tensioned such that it can be lifted by about 3mm in

the middle of the bar (Fig. 4). To decrease the chain

tension turn the knurling wheel down-wards (- direction

of arrow).

• Finally, tighten the T-screw (7) well by hand.

The tension in the chain has a major effect on the service

life of the cutting ﬁ ttings, and must therefore be checked

regularly. When the chain warms up to operating tem-

perature it will expand and must be retightened. A new

saw chain will have to be tightened more frequently until

it has reached its full length.

CAUTION: During the running-in period, the

chain must be more frequently tightened. The

chain must be immediately retightened if it

shakes or leaves the grove !

To tension the chain slightly loosen the T-screw (7). Then

turn the knurling wheel upwards (+ direction of arrow).

Tension the chain such that it can be lifted by about 3mm

in the middle of the bar, as shown in Fig. 4.

3.3. Connecting the chainsaw (Fig. 5)

We recommend to operate the chain saw in connec-

tion with a residual current operated device with a

maximum breaking current of 30mA.

This device is designed to be operated on a mains supp-

ly with a system impedance Z max at the point of con-

nection (house service connection) of max. 0.4 Ohm. The

user must ensure that the device is only operated on an

electricity supply system meeting these require-ments.

If required, system impedance data may be obtained

from the local public utility.

Use only extension cords that are approved for

outdoor use and are not lighter than rubber-

sheathed cables of type H07 RN-F according to

DIN/VDE 0282 with a diameter of at least 1.5 sq.

mm. They cords must be splash-proof. If the

connection cable of this device should be dam-

aged it must be replaced by a workshop named

by the manufacturer only as this work requires

the use of special tools. Mobile devices for out-

door use should be connected over a residual

current operated device.

This chainsaw is ﬁ tted with a strain-relief device to pro-

vide extra safety for the connection. First connect the

device plug with the connection line. Form a narrow loop

with the connecting cable, press on the button and swivel

the cable holder (18) out into position A. Now insert the

loop of cable from below into the mains lead cleat. Once

you have released the cable hook button, it will auto-

matically return to starting position B and the cable will

be held in place. Press the cable holder button again to

loosen the cable and pull out the cable.

3.4. Switching on (Fig. 6)

• Press with your thumbs the stopping button (15) on

the left side of the rear handle and then the operating

switch (9).

•

The stopping button (15) is used for unlocking the

switch-on mechanism and does not need to be pressed

again after the device is switched on.

• To switch off the device, release switch (9).

Attention: The sawing chain will start running

at high speed immediately. When putting the

saw down, make sure that the chain never gets

in touch with stones or metal objects.

4. Safety devices on your chain brake

4.1. Chain brake (Fig. 7)

This chain saw is equipped with a mechanical brake for

the chain. In the case of uncontrolled movements, when

the tip of the sax blade gets in contact with wood or a

solid object, the drive of the chain is immediately stopped

by activation of the hand guard (4), the motor will not

be stopped. This brake function is initiated by the back

of your hand on the front handle (2) pushing the hand

guard. The proper function of the saw chain brake shall

be checked before each use of the saw.

CAUTION: No buttons should be pressed when

the chain brake is released (hand protection

pulled back in the direction of the handle and

locked).

Always ensure before starting the chainsaw that

the hand protection (4) is locked in the operating

position. To do this, pull back the hand protection in

the direction of the handle.

4.2. Rundown brake
