• Always watch the rail tip. Take care when continu-
ing cuts which have already been started.
• Start the cut with the saw chain running!
• Always sharpen the saw chain correctly. Pay par-
ticular attention to the depth limiter being at the
correct height!
• Never cut through several branches at the same
time! When removing branches, ensure that no
other branch is touched.
• When cutting to length, pay attention to closely ad-
jacent branches.
Felling trees - only with appropriate training
m CAUTION
Watch out for broken or dead branches that can fall
down during sawing and cause serious injuries. Do
not saw near buildings or power lines if you do not
know which way the felled tree will fall. Do not work
at night, as this makes it harder to see, or in rain,
snow or storms, as the direction of tree fall is unpre-
dictable.
• Plan your work with the electric chainsaw in ad-
vance.
• The work area around the tree should be clear so
that you have a secure footing.
• The machine operator should always stay on the
higher level of the work area because the tree is
likely to roll or slide down after felling.
The following conditions can influence the direc-
tion of fall of a tree:
• Wind direction and speed.
• Inclination of the tree. The inclination is not always
recognisable due to uneven or sloping terrain. De-
termine the inclination of the tree using a plumb
bob or spirit level.
• Branch growth (and thus weight) on one side only.
• Surrounding trees or obstacles.
Look out for destroyed and rotten parts of the
tree. If the trunk is rotten, it can suddenly break and
fall on you. Ensure that there is sufficient space for
the falling tree. Keep a clearance of 2 1/2 tree lengths
to the nearest person or other objects. Engine noise
can drown out warning calls.
Remove dirt, stones, loose bark, nails, staples and
wire from the sawing point.

Clearing large trees is only permitted with corre-

The undercutting method is used to fell large trees.
A wedge is cut out of the side of the tree according
to the desired direction of fall. After the drop cut has
been made on the other side of the tree, the tree falls
towards the wedge.
m NOTE
If the tree has large supporting roots, these should
be removed before the notch is cut. If the chainsaw is
used to remove the supporting roots, the saw chain
should not touch the base so that the chain does not
become blunt.
Undercutting and felling of the tree (fig. B-C)
• First saw the upper cut (Pos. 1) of the wedge (Pos.
2) for the undercut. Cut into the tree 1/3 of the way.
Then saw the lower cut (Pos. 3) of the wedge (Pos.
2). Now remove the wedge that has been cut out.
• The felling cut (Pos. 4) 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. This
ensures that there is enough wood between the
drop cut (Pos. 4) and the wedge (Pos. 2) to act as
a hinge when it drops. This hinge is designed to
direct the tree in the right direction when it falls.
m NOTE
Before you finalise the drop cut, use wedges to wid-
en the cut if necessary to control the direction of the
drop. Use only wooden or plastic wedges. Steel or
iron wedges can cause the device to kick back and
be damaged.
• Watch out for signs that the tree is starting to fall,
such as cracking noises, the safety net opening or
movement in the upper branches.
• If the tree starts to fall, stop the chainsaw, put it
down and immediately leave the area along the
escape route.
• Do not cut partially felled trees with your chainsaw
to avoid injury. Pay special attention to partially
felled trees that are not supported. If a tree does
not fall completely, set the chainsaw down and as-
sist with a cable 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.
m 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.
