You can avoid accidents by not sawing
with the tip of the chain bar as this may
cause the saw to rear up suddenly. Always
use the complete safety equipment and
clothes when working with the saw.
Make sure your work piece is firmly secu-
red.
Use clamps to stop the work piece from
slipping. This also makes it easier to opera-
te the machine with both hands.
Kick-back will result in an uncontrollable motion of
the saw. This represents the danger of severe inju-
ries. Never saw with a slack or blunt chain. A
poorly sharpened chain increases the risk of kick-
back. Never saw above shoulder height.
20. Tips on chainsaw use
Sawing up wood
(See Fig. 4 and 5)
To saw up wood, please observe the safety regulati-
ons and proceed as follows: Make sure the wood to
be sawed cannot slip. Clamp short pieces of wood in
place before sawing. Saw only wood or wooden
objects. When sawing, make sure that no stones or
nails are touched as these could be thrown out and
damage the saw chain. Avoid bringing the running
saw into contact with wire fences or the ground.
When lopping off branches, support the machine as
far as possible and do not saw with the tip of the
chain bar. Watch out for obstacles such as tree
stumps, roots, ditches and hillocks as these could
cause you to fall.
Remember:
The chainsaw must be running before it comes into
contact with the wood!
To switch on: Press the safety lock-off (19) and
ON/OFF switch (18). Place the lowest claw (17) on
the wood. Raise the chainsaw by the rear grip (10)
and saw into the wood. Move the chainsaw back a
little and place the claw (17) further down. Be careful
when sawing splintered wood as pieces of wood may
be ripped off.
To switch off: Release the ON/OFF switch.
Pull the plug out of the power socket.
Remove the chainsaw from the wood only with
the saw chain still running. Anyone who saws
without a stop can be pulled forward.

Wood under tension

Danger:
Tree will rear up!
Fig. 10.2: Bottom side of trunk under
tension
Danger:
Tree will move downwards!
Fig. 10.3: Thick trunks and high tension
Danger:
Tree will move suddenly and
with immense force!
Fig. 10.4: Both sides of trunk under
tension
Danger:
Tree will move sideways!
Felling trees
To fell trees, observe all the safety regulations
and proceed as follows:
The chainsaw may be used to fell only trees which
are smaller in diameter than the length of the chain
bar. Never try to extract a jammed saw with the
motor still running. If the saw chain gets jammed,
release it using a wooden wedge.
Remember:
Danger zone: Falling trees can bring down
other trees with them. The danger zone is the-
refore twice the length of the tree being felled.
(Fig. 11)
Important:
Prior to cutting you must plan and provide for an
escape area (A). This escape area must be located
behind the expected felling direction (B) (Fig. 13).
Important:
Before performing the final cut, make sure there are
no spectators, animals or obstacles in the felling
path.
Felling trees is dangerous and requires practice.
If you are a beginner or inexperienced, do not try
to teach yourself but seek professional training.
(Fig. 12)
Felling direction:
First estimate the direction of fall, taking into
account the centre of gravity of the crown and
the wind direction. The chainsaw must be run-
ning before it comes into contact with the wood.
