► If signs of circulation problems occur: Seek
medical advice.
■ Sparks may occur if the rotating chain makes
contact with a hard object. Sparks may cause
a fire in an easily combustible location. This
can result in serious or fatal injuries and dam‐
age to property.
►
Do not work in an easily combustible loca‐
tion.
■ Note that the saw chain continues to rotate for
a short period after you release the trigger.
The rotating saw chain can cut the user. This
can result in serious injuries.
►
Wait for the chain to come to a standstill.
WARNING
■ The guide bar can be pinched when cutting
objects that are under tension. The user can
lose control of the saw and be seriously
injured.
►
Make a relieving cut in the compression side
(1) first, then perform bucking cut at the ten‐
sion side (2).
4.9 Reactive Forces
4.9.1 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. The operator
can lose control of the saw and be seriously or
fatally injured.
► 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.
■ In a rescue operation it may be necessary to
work with the bar nose. The risk of kickback is
greater if the bar nose is used for cutting. The
operator can lose control of the saw and be
seriously or fatally injured.
►
Make sure the user is trained for rescue
operations with a chainsaw.
4.9.2 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
