If you saw wood which is under tension, the

guide bar may become jammed. The user may
lose control of the chain saw and be seriously
injured.
► Make a relieving cut (1) in the compression
side (A) first, then perform a bucking (2) cut
at the tension side (B) from above, directly
above the first cut.

accidental contact with the saw chain and
damage the cables. This may result in serious
or fatal injury to the user.
► Do not operate in the vicinity of live cables.

■ Parts of the tree being removed and branches
can fall on bystanders or objects during the
felling operation. This can result in serious or
fatal injuries and damage to property.
► Determine direction of fall so that the area
in which the part of the tree being removed
falls is clear.
► Do not allow bystanders, children or ani‐
mals within 2.5 tree lengths of the work
area.
4.8 Reactive Forces
4.8.1 Kickback
Kickback can be caused for the following rea‐
sons:
– The rotating saw chain in the upper quadrant
of the bar nose makes contact with a hard
object and is suddenly braked.
– The rotating saw chain is pinched at the bar
nose.
The chain brake cannot prevent kickback.
WARNING
If kickback occurs, the saw can be thrown up
■
in the direction of the operator. Due to the spe‐
cial handle design (closely spaced handles)
there is a risk of the operator losing control of
the chainsaw and sustaining serious or fatal
injuries.
► Hold the saw firmly with both hands.
► Always keep your body out of the plane of
the cutting attachment.
► Use the working techniques described in
this instruction manual.
