Undercut and felling the tree (Fig. B-C)
• For the undercut, first cut the upper part (Pos. 1)
of the wedge (Pos. 2). Cut 1/3 of the way into the
tree. Then saw the lower part (Pos. 3) of the wedge
(Pos. 2). Now remove the wedge you have cut out.
• Afterwards, you can carry out the dropping cut on
the opposite side of the tree (Fig. 4). For this, start
about 5cm above the middle of the cut. In this way,
there is enough wood between the dropping cut
(Pos. 4) and the wedge (Pos. 2) so that it functions
as a hinge. This hinge is designed to guide the tree
in the right direction when falling.
m NOTICE
Before completing the dropping cut, if required, in-
crease the cut using wedges to control the direction
of the fall. Exclusively use wood or plastic wedges.
Steel or iron wedges can cause kickback and dam-
age to the device.
• Be aware of signs that the tree is beginning to
fall: Cracking sounds, the dropping cut opening or
movement in the upper branches.
• When the tree begins to fall, stop the saw, put it
down and leave immediately via your escape route.
• To prevent injuries, do not cut partly felled trees
with your saw. Beware especially of partly felled
trees which are not supported. If a tree does not
fall down completely, remove the saw and help
the process along with a cable winch, a pulley or
a towing vehicle.
Sawing a felled tree (log division)
The term „log division" describes the cutting up of a
felled tree into logs of the desired length.
m CAUTION
Do not stand on the log you are currently cutting.
The log could roll away and you may lose your foot-
ing and control of the device. Do not carry out sawing
work on sloping ground.
Important notices
• Only ever saw one log or branch.
• Be careful when cutting split wood. You may be hit
by sharp pieces of wood.
• Cut small logs or branches on a sawhorse. When
cutting logs, no other person must hold on to the
log. Do not secure the log with your leg or foot.
• Do not use the saw in areas where logs, roots and
other parts of the tree are entangled. Pull the logs
to a free area and cut the freed logs first.
Different cuts for log division (Fig. D)
m CAUTION
If the saw is jammed in a log, do not pull it out with
force. You may lose control of the device and suffer
severe injuries and/or damage the saw.

Stop the saw and drive a plastic or wooden wedge
into the cut until the saw can be pulled out easily.
Restart the saw and carefully continue with the cut.
Never start the saw when it is jammed in a log.
Topping (Fig. E, Pos. 1)
Topping starts at the upper side of the log where you
hold the saw against the log. Only use slight down-
wards pressure for topping.
Undercut (Fig. E, Pos. 2)
Start the undercut on the underside of the log and
hold the top edge of the saw against the log. Only
use slight upwards pressure for the undercut. Hold
the saw securely to control the device. The saw will
push backwards (in your direction).
m CAUTION
Never hold the saw the wrong way round for an un-
dercut. You do not have control of the device in this
position. Always make the first cut on the compres-
sion side of the log. The compression side of the log
is where the pressure of the log's weight is concen-
trated.
Log division without supports (Fig. F)
• Using topping (Pos. 1), saw 1/3 of the way into
the tree.
• Turn the log around and make a second top cut
(Pos. 2).
• When sawing on the compression side, make sure
the saw does not get jammed. See Figure for cuts
in logs on the compression side.
Log division with log or support
(Fig. G-H)
• Always remember to make the first cut (Pos. 1) on
the loaded side of the log.
• Cut 1/3 into the log for this.
• Make a second cut (Pos. 2).
Trimming and pruning
m CAUTION
Always be careful and protect yourself from kick-
back. Never let the moving chain at the tip of the
chain guide come in contact with other branches or
objects during trimming or cutting branches. Such
contact can lead to serious injuries.
m CAUTION
Never climb into the tree for trimming or pruning. Do
not stand on ladders, platforms etc. You could lose
your balance and control of the device.
