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 po-sition.
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 'Switch-
ing 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.
• Do not remove free-hanging branches from below.
Felling a tree (Fig. 9+10)
• Ensure that no one is within the felling area,
minimum distance: 2 tree lengths.
• Ensure that no one can be hit by falling branches or
the tree to be felled.
• Ensure that there is an escape path as shown in
Fig. 10.
• Ensure that you are standing firmly.
• Keep the working area free of objects.
• Always stand at the side of the tree during felling.
• First determine in which direction the tree is to be
felled. The felling notch is cut on this side of the trunk.
• First cut 1/3 of the trunk diameter horizontally into the
tree at the intended felling notch.
• Now cut the second part of the felling notch from
above at an angle of 45° to the first cut.
• Now make the felling cut exactly opposite to the felling
notch. The felling cut must run horizontal and a bit
higher than the felling notch.
• Do not cut completely through the tree. Leave about 1/
10 of the trunk diameter.
• Put wedges into the felling cut to bring the tree to fall.
Cutting a felling tree
• First support the trunk so that the section to be cut off
always hangs freely and does not lie on anything so
that the bar cannot jam.
• If the chain saw does become jammed, switch it off
immediately and withdraw the plug. Use the wedges to
free the bar.
• Avoid letting the saw chain coming into contact with the earth.
General instructions on working with a chainsaw
• Ensure that children and other spectators keep a safe
distance from the working area.
• Apply little pressure to the machine when sawing wood.
If the chain is keen, it will cut almost by itself through
the wood.
• If possible, always work with the chainsaw running at
high speed.
• Never try to continue sawing with a blunt chain. That
causes the motor to overheat and the loss of your right
to claim under guarantee. Always have a replacement
chain at hand.
• Allow the motor to cool off and make working breaks.
• After use always place the chain saw horizontally to
avoid oil dripping from the oil reservoir.
• Always use the chain cover when transporting the chain
saw.
