always maintain a proper grip and good
footing to control the power tool when
you experience such forces.
1.
2.
Be aware of the location of the guide
bar nose at all times.
Warning!
Never let the nose of the guide bar
contact any object. Do not cut limbs
with the nose of the guide bar. Be
especially careful near wire fences
and when cutting small, tough
limbs, which may easily catch the
chain.
An improperly mounted or damaged cyl-
inder housing or a damaged/deformed
muffler shell may interfere with the cool-
ing process of the catalytic converter.
To reduce the risk of fire or burn injury,
do not continue work with a damaged or
improperly mounted cylinder housing or
a damaged/deformed muffler shell.
The most common reactive forces are:
–
–
–
kickback,
pushback,
pull-in.
Kickback
3.
Cut only one limb at a time.
Kickback may occur when the moving
saw chain near the upper quadrant of
the bar nose contacts a solid object or is
pinched.
Your catalytic converter is furnished with
screens designed to reduce the risk of
fire from the emission of hot particles.
Due to the heat from the catalytic
reaction, these screens will normally
stay clean and need no service or
maintenance. If you experience loss of
performance and you suspect a clogged
screen, have your muffler maintained by
a STIHL servicing dealer.

Reactive Forces
Pull-in occurs when the chain on the
bottom of the bar is suddenly stopped
when it is pinched, caught or encounters
a foreign object in the wood. The
reaction of the chain pulls the saw
forward.
Warning!
The reaction of the cutting force of the
chain causes a rotational force on the
chain saw in the direction opposite to the
chain movement. This may cause the
bar to move upward.
Reactive forces may occur any time the
chain is rotating.The force used to cut
wood can be reversed and work against
the operator. If the rotating chain is sud-
denly stopped by contact with any solid
object such as a branch or is pinched,
the reactive forces may occur instantly.
These reactive forces may result in loss
of control, which, in turn, may cause
personal injury. An understanding of the
causes of these reactive forces may
help you avoid the element of surprise
and loss of control.
Pull-in frequently occurs when the chain
is not rotating at full speed before it
contacts the wood.
To Avoid Kickback
The best protection from kickback is to
avoid kickback situations:
To Avoid Pull-in
1.
Be alert to forces or situations that
may cause material to pinch the
chain at the bottom of the bar.
2.
Always start a cut with the chain
rotating at full speed.
Because of the design of the pole
pruner, the reactive forces experienced
when working with it are generally not as
severe as those encountered with a
chain saw. Nevertheless, you should
