• Maintain the device carefully. Check for misalign-
ment or binding of moving parts, breakage of parts
and any other condition that may affect the device’s
operation. Have damaged parts repaired before us-
ing the device. Many accidents are caused by poor-
ly maintained devices.
• Keep cutting tools sharp and clean. Properly main-
tained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
• Have the device serviced by qualified personnel.
Only use manufacturer’s recommended original
spare parts.
10.2 Creating the notch cut
Note
The fall notch determines the felling direction of the
tree to be felled.
Place the fall notch at right angles to the felling direc-
tion.
Saw as close to the ground as possible.
Support the chainsaw with the claw stop (15).
10.2.1 Creating the fall notch (fig. F)
• First start with the cut of the fall notch A. The depth
of the fall notch should be approx. 1/4 of the tree
diameter and have an angle of 45°- 60°.
10.2.2 Checking the felling direction (fig. G)
Place the chainsaw with the guide rail (16) at the bot-
tom of the notch cut.
If necessary, recut the notch cut accordingly.
10.3 Carrying out the felling cut (fig. F)
• Place the felling cut B approx. 2-3 cm higher than
the horizontal cut of the fall notch A. Make sure that
felling cut B is carried out exactly horizontally.
• Leave approx. 1/10 of the tree diameter, the break-
ing strip C before felling cut B. Breaking strip C
guides the tree to the ground like a hinge and se-
cures it against premature falling.
m
WARNING
Danger of accident!
Do not under any circumstances saw the breaking
strip C during felling cut B, otherwise the tree may fall
in an unpredictable direction!
Be prepared for the tree to “slide” uncontrollably when
falling on the cut.
Be prepared for the tree to “jump” uncontrollably in
one direction when it hits the ground.
• To prevent the chainsaw from jamming in felling cut
B, drive aluminium or plastic wedges into felling cut
B in good time. Do not use iron wedges.
• With the saw chain running, operate the front hand
guard (1). The chain brake must brake and lock the
saw chain at max. speed.
m
WARNING
Increased engine speed for too long with the chain
brake locked will damage the engine and the chain
drive.
If the saw chain (17) still moves, contact the customer
service.
10. Basic working instructions for
felling work
m
WARNING
Risk of injury!
Sawing and felling work as well as all related work
may only be carried out by specially trained and
briefed persons.
Note
Observe the country-specific regulations for felling
work and obtain information from the relevant author-
ity.
• Make sure that no one can be harmed by the falling
branches and trees.
• Only the persons required for the felling work may
be in the work area.
• Keep the work area at the trunk clear and tidy so
that operators have a safe standing area.
• Keep escape routes clear and tidy in order to be
able to leave the work area quickly.
• Do not carry out felling work in stronger wind condi-
tions, bad weather or poor visibility.
• Keep distances to the nearest workplace of at least
2 1/2 tree lengths.
10.1 Use and handling
• Never start the device before the guide bar (16), saw
chain (17) and chain cover (22) are correctly fitted.
• Do not cut wood that is lying on the ground or try to
cut roots that are sticking out of the ground. In any
case, make sure the saw chain (17) does not come
into contact with the soil, otherwise the saw chain
(17) will dull immediately.
• If you accidentally touch a solid object with the de-
vice, switch off the engine immediately and inspect
the device for any damage.
