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
between 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
designated as a break dimen-
sion.
R
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.
S

.
If the trunk diameter is larger
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.
6. 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 with-
drawal path.
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.

1. Log is lying on the ground:
Saw through the log completely
from above and ensure at the
end of the cut not to contact the
ground.
If you can turn the tree trunk, saw
two-thirds of the way through it.
Then turn the trunk around and
saw the rest of the way through
from above.
L
2. Log is supported at one end:
Start sawing from the bottom and
work your way up (with the upper
edge of the bar) a third of the way
into the diameter of the trunk to
prevent splitting. Then saw from
the top downwards with the lower
edge of the bar towards the first
cut to prevent the bar from be-
coming jammed in the wood.
M
3. Log is supported at both ends:
Start from the top and work down
(with the lower edge of the bar)
to a third of the diameter of the
trunk. Then saw from underneath
with the upper edge of the bar
until the two cuts meet.

4. Sawing on a sawhorse:
Hold the electric chainsaw steady
with both hands, keeping the saw
in front of you while sawing. Once
the saw is through the wood,
