can fall on bystanders or objects during the
felling operation. This can result in serious or
fatal injuries and damage to property.

in which the part of the tree being removed
falls is clear.

Kickback
Kickback can be caused for the following rea‐

– 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.
► Do not cut with the upper quadrant of the
bar nose.
► Always cut with a properly sharpened and
tensioned saw chain.
► Use a reduced kickback saw chain.
► Use a guide bar with a narrow radius nose.
► Always cut with the chain running at full
speed.
4.8.2
Pull-in
The saw is pulled away from the operator when
the bottom of the bar is used for cutting.
WARNING
■ If the rotating chain makes contact with a hard
object and is suddenly pinched, the saw is
abruptly jerked away from the operator. The
operator can lose control of the saw and be
seriously or fatally injured.
► Hold the saw firmly with both hands.
► Operate the saw as described in this
