4. Felling back cut (B):
Q
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
stem not sawn through is called
a stay (felling gib). The stay pre-
vents the tree from turning and
falling in the wrong direction. Do
not saw through the stay.
5. As you approach the felling cut
R
on the stay the tree should start
falling. If it becomes apparent
that the tree may not fall in the
required direction or is lean-
ing back, and the saw chain is
jamming, stop felling and use
wedges made of wood, plastic or
aluminium to open the cut and to
tilt the tree in the required felling
line.
6. If the trunk diameter is larger
S
than the length of the chain bar,
make two cuts.
For safety reasons, we advise
inexperienced users not to fell
any logs with a rail length which
is smaller than the trunk diam-
eter.
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 chainsaw down and leave the
workplace using the withdrawal
path.
Maintenance and
