Branches growing (and therefore weight) only on one
side
Surrounding trees or obstacles
Look out for destroyed or decayed parts of the
tree. If the trunk is decayed, it can suddenly break
and fall on you. Make sure there is sufficient space
for the falling tree. Keep a distance of 2½ tree lengths
to the next person or other objects. The sound of the
motor can drown out warning cries.
Remove dirt, stones, loose bark, nails, brackets and
wire from the sawing area.
m Ensure you have a free escape route (Fig. A)
Position 1: Escape route
Position 2: Falling direction of the tree
Felling of large trees - only with relevant training
(from 15cm diameter)
The undercutting method is used for felling large
trees. For this, a wedge is cut out from the side of the
tree according to the required falling direction. After
the dropping cut has been made on the other side of
the tree, it will fall in the direction of the wedge cut.
m NOTICE
If the tree has large prop/buttress roots, these should
be removed before the wedge is cut. If the saw is
used for removing the prop/buttress roots, the saw-
chain should not touch the ground so the chain does
not become blunt.
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 move-
ment 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 footing 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 cut-
ting 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 under-
cut. You do not have control of the device in this posi-
tion. Always make the first cut on the compression side
of the log. The compression side of the log is where
the pressure of the log's weight is concentrated.
