Operating Instruction
GB-7
• After use, lay the chainsaw horizontally on some ab-
sorbing surface. The oil spread on the blade, chain and
drive may lead to some further dripping of oil.
2. Assembling the blade and chain
(Fig. 3)
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 direc-
tion 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 downwards (- 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 fittings, 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. 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
supply with a system impedance Z max at the point of
connection (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
out-door 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 fitted with a strain-relief device to
provide extra safety for the connection. First connect
the device plug with the connection line. Then form the
connection line into a tight loop and push this through the
safety web on the lower side of the machine. Hang the
loop into the hook as shown in Fig. 6. The plug connec-
tion is now secure against automatic release.
4. Switching on
(Fig. 2 + 6)
• Hold the saw securely with both hands so that the
thumbs and fingers are wrapped around the handle of
the chain saw (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.
Safety devices on your chain brake
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 direc-
tion of the handle.
