• 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 con-
nection cable of this device should be damaged
it must be replaced by a workshop named by
the manufacturer only as this work requires the
use of special tools. Mobile devices for outdoor
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)
• Hold the saw securely with both hands so that the
thumbs and fingers are wrapped around the handle of
the chain saw.
• 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.
Warning!
The prolonged utilisation of a tool will subject the user to
vibration and shocks that could lead to Raynaud's syndro-
me or Carpal tunnel syndrome.
This condition reduces the ability of the hand to sense
and regulate temperature, causes numbness and a sen-
sation of heat and can lead to damage to the nervous
system and the circulatory system and to necrosis.
Not all factors that lead to Raynaud's syndrome are
known but cold water, smoking and illnesses that impact
the blood vessels and the circulatory system as well as
severe or long-lasting exposure to vibrations are known
to be factors in the development of Raynaud's syndro-
me. Observe the following in order to reduce the risk of
Raynaud's syndrome and Carpal tunnel syndrome:
• Wear gloves and keep your hands warm.
• Make sure the device is well maintained. A tool with
loose components or with damaged or worn-out
dampers will have a disposition towards increased
vibrations.
• Always hold the handle firmly but do not clutch it cons-
tantly with excessive force. Take breaks often.
All of the above precautions cannot exclude the risk of
Raynaud's syndrome or Carpal tunnel syndrome. There-
fore, with long-term or regular use it is advisable to keep
a close watch on the condition of your hands and fingers.
Seek medical attention immediately in the event of any of
the above symptoms appearing.
