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:
2. Escape area:
3. Cutting notch (A):
).
4. Felling back cut (B):
Remove hanging branches by
positioning the cut from above
the branch. With removal of
branches, never work higher
than shoulder level.
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).
Make a felling notch in the di-
rection in which you wish the
tree to fall. Start with the bot-
tom, horizontal cut. The cut
depth should be around 1/3 of
the trunk diameter. Now make a
slanted saw cut from above at
an angle of roughly 45° to meet
exactly with the bottom saw cut.
This helps avoiding that the
chainsaw or the guide rail jams
when making the second chip
carving.
Never step in front of a tree
which is notched.
Make the back cut from the
other side of the log, where you
stand to the left of the log and
saw with the chainsaw pulling.
The back cut must run horizon-
tally 5 cm above the horizontal
notched cut.
The back cut should be so deep
that the separation distance be-
tween the back cut and the notch
cutting line is at least 1/10 of the
trunk diameter. The part of the log
