Reduced Kickback Bars
STIHL green labeled reduced kickback
bars are designed to reduce the risk of
kickback injury when used with STIHL
green labeled low kickback saw chains.
WARNING
When used with other, more aggressive
saw chains, these bars may be less
effective in reducing kickback.
WARNING
For a properly balanced saw and in
order to comply with the chain saw
standard, use only bar lengths listed in
the specifications chapter of the
instruction manual for your chain saw.
To avoid kickback
The best protection from personal injury
that may result from kickback is to avoid
kickback situations:
1. Hold the chain saw firmly with both
hands and maintain a secure grip.
Don't let go.
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 near wire fences
and when cutting small, tough limbs
and branches which may easily
catch the saw chain.
4. Don't overreach.
5. Don't cut above shoulder height.
6. Begin cutting and continue at full
throttle.
7. Cut only one branch at a time.

8. Use extreme caution when
reentering 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 branch or
other forces that may cause the cut
to close and pinch the saw chain.
11. Maintain saw chain properly. Cut
with a correctly sharpened, properly
tensioned saw chain at all times.
12. Stand to the side of the cutting path
of the chain saw.
Bow Guides
WARNING
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 saw chain will not
significantly reduce the risk of kickback
injury when used on a bow guide.
A = Pull-in
Pull-in occurs when the saw 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 saw chain pulls the chain
saw forward and may cause the
operator to lose control.
Pull-in frequently occurs when the
bumper spike of the chain saw is not
held securely against the tree or limb
and when the saw chain is not rotating at
full speed before it contacts the wood.
WARNING
Use extreme caution when cutting small
size branches which may easily catch
the saw chain, be whipped towards you
or pull you off balance.
To avoid pull-in
1. Always start a cut with the saw
chain rotating at full speed and the
bumper spike in contact with the
wood.
2. The risk of pull-in may also be
reduced by using wedges to hold
open the kerf or cut.
