4. Felling back cut (B):
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 horizontally 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 not sawed through is desig-
nated 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 direc-
tion or if it bends back, and if the
chainsaw is stuck, discontinue the
felling cut and use wooden, plas-
tic or aluminium 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
100
and leave the workplace us-
ing 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 pre-
vent 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 possible
to the electric chainsaw. As far as pos-
sible, 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 separately.
• Cut off smaller branches, as shown in
Figure , in one go.

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.
