Undercutting and felling of the tree (Fig. B - C)
• Saw a notch at right angles to the direction of fall
with a depth of 1/3 of the tree diameter. First make
the lower horizontal notch cut (Fig. B, Pos. 1). This
avoids jamming the saw chain or guide rail when
setting the second notch (Fig. B, Pos. 2). Now re-
move the wedge that has been cut out.
• The felling cut (Fig. B, Pos. 3) can then be carried
out on the opposite side of the tree. To do this,
place it approx. 5 cm above the centre of the notch.
Make the felling cut parallel to the horizontal notch
cut. Saw the felling cut (Pos. 3) only deep enough
to leave a bar (Pos. 4) (felling bar) that can act as a
hinge. The bar prevents the tree from turning and
falling in the wrong direction. Do not saw through
the bar.
Note: As the felling cut approaches the bar, the
tree should begin to fall. If it appears that the tree
is potentially not falling in the desired direction or
is leaning back and the saw chain is jammed, stop
the felling cut and use wooden, plastic or aluminium
wedges to open the cut and move the tree to the de-
sired fall line.
When the tree starts to fall, remove the electric chain-
saw from the cut, switch off, lay down and leave the
danger zone via the planned escape route. Watch
out for falling branches and do not trip.
• Look for signs that it is beginning to fall: Cracking
noises, opening drop section or movement in the
upper branches.
• Do not cut partially felled trees with your saw to
avoid injury. Pay special attention to partially felled
trees that are not supported. If a tree does not fall
completely, set the saw down and assist with a ca-
ble winch, pulley block or tractor.
Sawing a felled tree (trunk division)
The term "trunk division" refers to the cutting of a
felled tree into trunks of the desired length.
Caution! Do not stand on the trunk you are cutting.
The trunk could roll away and you lose your footing
and control of the device. Never carry out sawing
work on sloping ground. Make sure you stand se-
curely and distribute your body weight evenly on both
feet. If possible, the trunk should be underpinned and
supported by branches, beams or wedges.
Important information
• Only saw one trunk or branch at a time.
• Be careful when cutting splintered wood. You could
be hit by sharp wood particles.
• Cut small trunks or branches on a metal work tres-
tle. When cutting trunks, no other person shall hold
the trunk. Do not secure the trunk with your leg or
foot either.

• Do not use the saw for places where trunks, roots
and other tree parts are intertwined. Pull the trunks
to a free spot, taking the exposed trunks first.
Different cuts for trunk division
(Fig. D)
Caution! If the saw gets jammed in a trunk, do not
pull it out by force. You can lose control of the device
and cause serious injury and/or damage the saw.
Stop the saw and drive a plastic or wooden wedge
into the cut until the saw can be easily pulled out.
Leave the saw on again and carefully reapply the cut.
Never start the saw when it is jammed in a trunk.
Top cut (Fig. E, Pos. 1)
Start at the top of the trunk for sawing, holding the
saw against the trunk. Apply only light downward
pressure to the top cut.
Undercut (Fig. E, Pos. 2)
Set for undercutting on the underside of the trunk,
holding the top of the saw against the trunk. When
undercutting, only exert a slight upward pull. Hold the
saw well to be able to control the device. The saw
pushes backwards (towards you).
Caution! Never hold the saw upside down for an un-
dercut. In this position you have no control over the
device.
Always make the first cut on the compression side of
the trunk. The compression side of a trunk is where
the pressure of the trunk weight is concentrated.
Trunk division without nozzles (Fig. F)
• When the entire length of the log rests evenly, saw
from above (Pos. 1).
• Be careful not to saw into the ground.
Trunk division resting on one side (Fig. G)
• If the log rests on one end, saw the first cut (Pos.
1) from the underside (1/3 of the log diameter) to
avoid splintering
• Second cut from the top (2/3 diameter) at the level
of the first cut to avoid jamming.
Trunk division resting on both sides (Fig. H)
• When the log is supported at both ends, saw the
first cut (Pos. 1) from the top (1/3 of the log diame-
ter) to avoid splintering.
• Second cut from the bottom (2/3 diameter) at the
level of the first cut to avoid jamming.
Limbing and bucking
Caution! Always take care and protect yourself from
kickback. Never allow the running chain at the tip of
the guide rail to come into contact with other branch-
es or objects when limbing or pruning. Such contact
can cause serious injury.
