Warning!
A dull or improperly sharpened chain
may reduce or negate the effects of the
design features intended to reduce
kickback energy. Improper lowering or
sharpening of the depth gauges or
shaping of the cutters may increase the
chance and the potential energy of a
kickback. Always cut with a properly
sharpened chain.
!
Warning!
Reduced kickback bars and low
kickback chains do not prevent
kickback, but they are designed to
reduce the risk of kickback injury. They
are available from your STIHL dealer.
!
Warning!
Even if your saw is equipped with a
Quickstop chain brake, a reduced
kickback bar and/or low kickback chain,
this does not eliminate the risk of injury
by kickback. Therefore, always observe
all safety precautions to avoid kickback
situations.

To avoid kickback
The best protection from personal injury
that may result from kickback is to avoid
kickback situations:
1. Hold the chainsaw firmly with both
hands and maintain a secure grip.
2. Be aware of the location of the guide
bar nose at all times.
3. 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 when cutting
small, tough limbs, small size brush
and saplings which may easily catch
the chain.
4 Don't overreach.
5. Don't cut above shoulder height.
6. Begin cutting and continue at full
throttle.
7. Cut only one log at a time.
8. Use extreme caution when re-
entering a previous cut.
9. Do not attempt to plunge cut if you
are not experienced with these
cutting techniques.
10. Be alert for shifting of the log or
other forces that may cause the cut
to close and pinch the chain.
11. Maintain saw chain properly. Cut
with a correctly sharpened, properly
tensioned chain at all times.
12. Stand to the side of the cutting path
of the chainsaw.
A = Pull-in:
Pull-in occurs when the chain on the
bottom of the bar is suddenly stopped.
The chain on the bottom of the bar stops
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. Pull-in frequently occurs
when the bumper spike of the saw is not
held securely against the tree or limb
and the chain is not rotating at full speed
before it contacts the wood.
!
Warning!
Use extreme caution when cutting small
size brush and saplings which may
easily catch a chain and pull you off
balance.
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.
2. Pull-in may also be prevented by
using wedges to open the kerf or
cut.
