Always ensure adequate lighting or good light
conditions when working with the machine.
After starting, release the throttle lever to ensure
that the engine speed assumes the idle speed,
only then can the chain brake be released.
Attention when walking backwards, danger
of tripping!
Remove cut branches immediately from the
work area to prevent injury.
The on/off switch and the safety switch must
not be locked.
Safety devices of a chain saw:
Rear hand guard:
The wide plate at the bottom of the handle
protects the operator's hand from
operator's hand from injuries caused by a chain
that may break and strike.
Chain catcher:
The chain catcher in the chainsaw housing
"catches" the chains in the event of a breakage
and Prevents the chain from hitting the operator
or being thrown out.
Chain brake:
The chain brake stops the saw chain within a few
milliseconds in the event of a kickback triggered
by the back of the user's hand, thus preventing
serious injuries.
Working instructions
The operating instructions contain important
information on how to work safely and profes-
sionally with the chain saw and how to avoid
hazards. Should a blockage nevertheless occur
between the cut material and the saw chain,
then switch it off immediately. Wait until the
saw chain has come to a standstill. Remove the
spark plug connector and put on cut-resistant
gloves to remove the blockage. If it is necessary
to remove the guide bar (guide bar), follow the
instructions given in the Installation chapter.
After removing the blockage and reassembling,
a test run must be carried out. If vibrations or
mechanical noises are detected, stop work and
contact an authorized service center. If this haz-
ard occurs frequently, we recommend training.
Felling a tree
If two or more persons cut and fell at the same
time, the distance between the fellers and the
cutters should be at least twice the height of
the tree to be felled. When felling trees, care
must be taken to ensure that other persons are
not exposed to danger, that no utility lines are
in the way and that no material damage can be
caused. If a tree comes into contact with a utility
line, the utility company must be informed
immediately. When sawing on slopes, the chain
saw operator should be on the ground above
the tree to be felled, as the tree is likely to roll or
slide downhill after felling.
An escape route should be planned and, if
necessary, cleared prior to the commencement
of felling operations. The escape route should
lead diagonally backwards from the expected
fall line.
Before you start felling, consider the natural
inclination of the tree, the position of larger
branches and the direction of the wind in order
to estimate the direction in which the tree will
fall.
Remove dirt, stones, loose bark, nails, staples
and wire from the tree.
Do not try to cut trees that have rotted or been
damaged by wind, fire, lightning, etc. This is
extremely dangerous and should be done by
professional tree surgeons.
1. Notch cut
At right angles to the direction of fall, saw a
notch with a depth of 1/3 of the tree diameter.
First make the lower horizontal cut. This avoids
jamming the saw chain or guide bar when mak-
ing the second cut.
2. Felling cut
Make the felling cut at least 50 mm higher than
the horizontal notch cut. Make the felling cut
parallel to the horizontal notch cut. Make the
felling cut so that a strip (felling strip) remains,
which can act as a hinge. The strip prevents
the tree from turning and falling in the wrong
direction. Do not saw through the strip. As the
felling cut approaches the strip, the tree should
begin to fall. If there is a danger that the tree will
not fall in the desired direction or it swings back
and the saw chain jams, stop cutting before the
felling cut is complete and use wooden, plastic
or aluminium wedges to expand the cut and
make the tree fall in the desired direction.
When the tree begins to fall, pull the chain saw
out of the cut, turn off the engine, turn off the
chain saw and follow the planned escape route.
Pay attention to falling branches and do not trip.
Removing woody roots. Woody roots are large
roots that protrude above the soil from the trunk
of the tree. Large woody roots must be removed
before felling. First cut the woody root horizon-
tally and then vertically. Remove the loose root
piece from the working area. Follow the correct
procedure for felling the tree after removing the
large woody roots.
Cutting a tree trunk to length
Cutting to length involves cutting a tree trunk
into pieces. It is important that you have a firm
footing and that your weight is evenly distrib-
