If the saw chain jams, you
do not attempt to pull out the
electric chainsaw using power.
There is a danger of injury here.
Switch off the motor and use a
lever or wedge to free the elec-
tric chainsaw.
Felling trees
A lot of experience is necessary
in felling trees. Cut down trees
only when you can safely han-
dle the electric chainsaw. In no
case should you use the electric
chainsaw if you feel unsure
about anything.
For safety reasons, we advise
inexperienced users not to fell
any logs with a rail length which is
smaller than the trunk diameter.
• Ensure that no people or animals
are in the field of action. The safety
distance between the tree to be felled
and the nearest-located workplace
must be 2 ½ tree lengths.
• Note the felling direction:
The user must be able to move safely
near the felled tree, to saw off the tree
easily and remove branches.It is to
be avoided that the felled tree snags
itself on another tree. Note the natural
felling direction, which is dependent
on the slope and curvature character-
istic of the tree, wind direction and the
number of branches.
• For sowing work on hillsides, the user
of the chainsaw should stay in the area
above the tree that is to be felled, as
the tree will probably roll down or slide
off downhill after being felled.
• Small trees, with a diameter of 15-
18 cm, can usually be sawn off with
one cut.
• In case of trees with a larger diameter,
a notched cut and a back cut must be
implemented (see diagram ).
Do not fell any trees when a
strong or changing wind is
blowing, if the danger of prop-
erty damage exists or if the tree
could fall on electric wires.
When felling trees, ensure that
no other persons are exposed to
hazards, that no supply lines are
hit, and that no property damage
is caused. If a tree should come
into contact with a supply line,
the utility company must be in-
formed immediately.
Immediately after termination of
the sawing procedure, remove the
ear protection so that you can hear
hooter and alarm signals.
1.
Removal of branches
:
Remove hanging branches by
positioning the cut from above
the branch. With removal of
branches, never work higher
than shoulder level.
2.
Escape area:
Remove the undergrowth around
the tree to ensure an easy
escape. The escape area (1)
should be around 45° either side
behind the planned felling direc-
tion (2).
3.
Cutting notch (A):
Make a felling notch in the direc-
tion in which you wish the tree to
fall. Start with the bottom, hori-
zontal cut. The cut depth should
