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 in-
experienced 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 dis-
tance between the tree to be felled
and the nearest-located workplace
must be 2 1/2 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 charac-
teristic 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 blow-
ing, if the danger of property dam-
age 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 dam-
age is caused. If a tree should
come into contact with a supply
line, the utility company must be
informed 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
direction (2).
3.
Cutting notch (A):
Make a felling notch in the direc-
tion in which you wish the tree to
