• 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 temper-
ature 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 chainsaw 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. 0.315 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 outdoor use and are not lighter than rub-
ber-sheathed cables of type H07 RN-F accord-
ing 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 devic-
es for outdoor use should be connected over a
residual current operated device.
To protect the connection cable from strains this chain
saw is equipped with a strain relief. First, connect the
tool’s plug with the mains cable. Then, form a tight loop
with the connection cable and put this loop through the
opening on the rear side of the handle. Put the loop over
the strain relief hook as shown in the corresponding
figure.
Now the plug-connection is secured against unin-
tentional disconnection.
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 di-
rection 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 activat-
ing the operating switch 9, as described in the section
‘Switching on’.
4. Chain catch bolt
(Fig. 8)
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. 9 - 17)
CAUTION!
Only saw logs with a diameter less than the saw’s
cutting length. Lay people and home users may not
use the plunge cut process to saw and fell trees, as
this causes a kickback on the chain saw and can
therefore result in severe injuries and even death in
certain circumstances.
