10. Be alert for shifting of the log or
other forces that may cause the cut
to close and pinch the chain.
To avoid Pull-in
1.
Always start a cut with the chain
rotating at full speed and the
bumper spike in contact with the
wood.
Warning!
11.
Maintain saw chain properly. Cut
with a correctly sharpened, properly
tensioned chain at all times.
Do not mount a bow guide on any
STIHL chain saw. Any chain saw
equipped with a bow guide is potentially
very dangerous. The risk of kickback is
increased with a bow guide because of
the increased kickback contact area.
Low kickback chain will not significantly
reduce the risk of kickback injury when
used on a bow guide.
2.
The risk of pull-in may also be
reduced by using wedges to open
the kerf or cut.
12.
Stand to the side of the cutting path
of the chain saw.

1.
Hold the chain saw firmly with both
hands and maintain a secure grip.
Don’t let go.
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 and may cause the operator to
lose control.
Pushback occurs when the chain on the
top of the bar is suddenly stopped when
it is pinched, caught or encounters a
foreign object in the wood. The reaction
of the chain may drive the saw rapidly
straight back toward the operator and
may cause loss of saw control.

3.
Be aware of the location of the guide
bar nose at all times.
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
Pushback frequently occurs when the
top of the bar is used for cutting.
Pull-in frequently occurs when the
bumper spike of the saw is not held
securely against the tree or limb and
when the chain is not rotating at full
speed before it contacts the wood.
limbs, small size brush and saplings
which may easily catch the chain.
To avoid Pushback
1.
Be alert to forces or situations that
may cause material to pinch the top
of the chain.

6.
Don't overreach.
Don't cut above shoulder height.
Warning!
2.
3.
Do not cut more than one log at a
time.
Begin cutting and continue at full
throttle.
Use extreme caution when cutting small
size brush and saplings which may eas-
ily catch the chain, be whipped towards
you or pull you off balance.
Do not twist the saw when
withdrawing the bar from a plunge
cut or underbuck cut because the
chain can pinch.

Cut only one log at a time.
Use extreme caution when
reentering a previous cut.
9.
Do not attempt to plunge cut if you
are not experienced with these
cutting techniques.
