GB
not sawed through is designated
as a break dimension.
The hinge prevents the tree from
turning and falling in the wrong
direction. Do not cut through the
hinge.
When the felling cut nears the
hinge, the tree should begin
to fall. If it becomes apparent
that the tree might not fall in the
desired direction or if it bends
back, and if the chainsaw is
stuck, discontinue the felling cut
and use wooden, plastic or alu-
minium wedges to open the cut
and fell the tree to fall into the
desired fall line.
5. Insert a felling wedge or a crow-
bar into the back cut, as soon
as the depth of cut permits this,
in order to prevent a jamming of
the chain bar.
6. If the trunk diameter is larger
than the length of the chain bar,
make two cuts.
7. After carrying out of the back
cut, the tree falls by itself or with
the aid of the felling wedge or
crowbar.
As soon as the tree begins to
fall, pull out the saw from the
section, stop the motor, place
the electric chainsaw down and
leave the workplace using the
withdrawal path.
Pay attention to falling branches
and do not stumble.
Limbing
Limbing is the designation for the sawing
off of branches and boughs from a felled
tree.

Many accidents occur during the
removal of branches. Never cut
tree limbs when you are standing
on the log. Keep the spring-back
area in mind if branches are under
tension.
•
Do not remove support branches until
after the sawing off.
•
Branches under tension must be
sawed from below to above, in order
to prevent jamming of the chainsaw.
•
When working on thicker branches,
use the same technique as when you
are sawing up a felled trunk. Work to
the left of the log and as near as pos-
sible to the electric chainsaw. As far as
possible, the weight of the saw should
rest on the log.
•
Change position to saw off branches
on the other side of the trunk.
•
Branches sticking out are cut off sepa-
rately.
•
Cut off smaller branches, as shown in
Figure
, in one go.
Bucking
This refers to sawing up a felled tree trunk
into smaller sections.
• Ensure that the saw chain does not
come in contact with the ground during
sawing.
• Make sure you have a secure stance
and, in the case of sloping ground,
stand above the log.
• Ensure that you have secure footing
and balance your body weight evenly
on both feet. If possible, the trunk
should be protected and supported by
branches, logs or wedges. Follow the
simple instructions for easy sowing.
