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
saw
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 activa-
tion 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 4. 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 be-
fore starting the chainsaw that the hand pro-
tection 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 run-
down 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 outwards 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 hori-
zontal 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.
