certain powerheads, comply with § 5.11
of ANSI B 175.1-2000. Check with your
STIHL dealer for such combinations.
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, 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.
Low Kickback Chain
Some types of saw chains have
specially designed components to
reduce the force of nose contact
kickback. STIHL has developed low
kickback chain for your powerhead.
"Low kickback saw chain" is a chain
which has met the kickback
performance requirements of § 5.11.2.4
of ANSI B 175.1-2000 (Gasoline-
Powered Chain Saws-Safety
Requirements) when tested in its
original condition on a selected
representative sample of chain saws
below 3.8 cubic inches (62 cm³)
displacement specified in ANSI
B 175.1-2000.
WARNING
There are potential powerhead and bar
combinations with which low kickback
saw chains can be used which have not
16
been specifically certified to comply with
the 45° computer derived kickback
angle of § 5.11 of ANSI B 175.1-2000.
Some low kickback chains have not
been tested with all powerhead and bar
combinations.
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.
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 chains.
WARNING
When used with other, more aggressive
chains, these bars may be less effective
in reducing kickback.
WARNING
For a properly balanced saw and in
order to comply with § 5.12.1 of ANSI
B 175.1-2000, use only bar lengths
listed in the specifications chapter of the
instruction manual for your chain saw
powerhead.
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 chain will not significantly
reduce the risk of kickback injury when
used on a bow guide.
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.
Do not 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 chain.
4.
Do not overreach.
5.
Do not 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.
