eliminate the risk of injury by kickback. Therefore, always observe all safety precautions to avoid kickback situations. Low Kickback Saw Chain Some types of saw chains have specially designed components to reduce the force of nose contact kickback. STIHL has developed low kickback saw chain for your chain saw. A "low kickback saw chain" is a saw chain that has met the kickback performance requirements of ANSI/OPEI B175.1-2012 when tested according to the provisions specified in ANSI/OPEI B175.1-2012. WARNING There are potential chain saw and bar combinations with which low kickback saw chains can be used which have not been specifically certified to comply with the 45° computer derived kickback angle of the chain saw standard. Some low kickback saw chains have not been tested with all chain saw and bar combinations. WARNING A blunt or incorrectly sharpened saw chain may reduce or negate the effects of the design features intended to reduce kickback energy. Improper lowering or sharpening of the depth gauges as well as changing the shape of the cutters may increase the risk and the energy of kickback. Always cut with a properly sharpened saw chain. 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, small size brush and saplings 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. English 7. Cut only one log 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 log 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. MS 441 C-M 17

eliminate the risk of injury by kickback.
Therefore, always observe all safety
precautions to avoid kickback situations.
Low Kickback Saw Chain
Some types of saw chains have
specially designed components to
reduce the force of nose contact
kickback. STIHL has developed low
kickback saw chain for your chain saw.
A "low kickback saw chain" is a saw
chain that has met the kickback
performance requirements of
ANSI/OPEI B175.1
-
2012 when tested
according to the provisions specified in
ANSI/OPEI B175.1
-
2012.
WARNING
There are potential chain saw and bar
combinations with which low kickback
saw chains can be used which have not
been specifically certified to comply with
the 45° computer derived kickback
angle of the chain saw standard. Some
low kickback saw chains have not been
tested with all chain saw and bar
combinations.
WARNING
A blunt or incorrectly sharpened saw
chain may reduce or negate the effects
of the design features intended to
reduce kickback energy. Improper
lowering or sharpening of the depth
gauges as well as changing the shape of
the cutters may increase the risk and the
energy of kickback. Always cut with a
properly sharpened saw chain.
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, small size brush and saplings
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 log 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 log 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.
