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
temperature 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
connection with a residual current operated device
with a maxi-mum 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
requirements. 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
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
connection is now secure against automatic release.
4. Switching on (Fig. 2)
• 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. 6)
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.
2. Rundown brake
In accordance with the latest regulations, this chain saw
is equipped with a mechanical rundown brake. This brake
is connected to the chain brake and stops the running
chain after the chain saw has been switched off.
It is activated by releasing the ON/OFF switch. The
rundown brake avoids injuries through the coasting of
the chain.
3. Safety starting lock
The starting delay that is effective for about 3 sec. after
each switch-off of the chain saw provides for additional
safety.
Thus, for your own safety, there is a delay of 3 seconds
before the device can be switched on again after each
time it is switched off.
Only after this phase, the saw may be operated again
by pushing the locking button 15 and subsequently
activating the operating switch 9, as described in the
section 'Switching on'.
4. Chain catch bolt (Fig. 7)
This chainsaw is fitted with a chain catch bolt (17). If the
chain breaks when the saw is in operation, the chain bolt
will catch the loose chain end and thus prevent injury to
the operator's hand.
Instructions on working properly with the
chain saw
(Fig. 8 - 10)
Removing branches (Fig. 8)
• Ensure that you are standing firmly.
• Cut a deep notch from below into the branch about 15
cm from the trunk.
• Now cut the branch from above about 5 cm further out-
wards from the lower notch until the branch drops off.
• In order to remove the rest, cut from below about 1/3
into the remaining branch close to the trunk.
• Cut into the branch from above until the branch has
been removed completely.
