English
Begin cutting with the saw at full throttle
and engage the spiked bumper firmly in
the wood, and then continue cutting.
Never work without the spiked bumper
because the saw may pull you forwards
and off balance. Always engage the
spiked bumper securely in the tree or
limb.
Note when reaching the end of a cut that
the saw is no longer supported in the
kerf. You have to take the full weight of
the unit since it might otherwise go out of
control.
Felling
Do not attempt felling unless you have
been trained in the necessary
techniques. To reduce the risk of
accidents and injury, do not attempt
felling or limbing if you are not an
experienced chain saw user.
Observe all country-specific regulations
on felling techniques.
Check that there are no other persons in
the felling area – other than helpers.
Make sure no-one is endangered by the
falling tree – the noise of your engine
may drown any warning calls.

Determine direction of fall and escape
paths
Select gap in stand into which you want
the tree to fall.
Pay special attention to the following
points:
The natural lean of the tree
–
Any unusually heavy limb structure,
–
damage
The wind direction and speed – do
–
not fell in high winds
Sloping ground
–
Neighboring trees
–
Snow load
–
Soundness of tree – take special
–
care if trunk is damaged or in case
of deadwood (dry, decayed or rotted
wood)

A Direction of fall
B Escape paths
Establish paths of escape for
–
everyone concerned – opposite to
direction of fall at about 45°.
Remove all obstacles from escape
–
paths.
Place all tools and equipment a safe
–
distance away from the tree, but not
on the escape paths.
Always keep to the side of the falling
–
tree and only walk away along the
preplanned escape path.
On steep slopes, plan escape
–
routes parallel to the slope.
When walking away along the
–
escape path, watch out for falling
limbs and watch the top of the tree.
Preparing work area at base of tree
First clear the tree base and work
–
area from interfering limbs and
brush to provide a secure footing.
Clean lower portion of tree base
–
(e.g. with an axe) – sand, stones
and other foreign objects will dull the
saw chain.
