chains. Cutting attachments with green
warning decals or green labels on the
packaging are designed to reduce the
risk of kickback injury. The matching of
green decaled powerheads under
3.8 cubic inches (62 cm³) displacement
with green labeled bars and green
labeled chains gives compliance with
the computed kickback angle
requirements of ANSI B 175.1-2000
when the products are in their original
condition. Products with yellow decals or
labels are for users with extraordinary
cutting needs and experience and
specialized training for dealing with
kickback.
STIHL recommends the use of its green
labeled reduced kickback bars, green
labeled low kickback chains and a
STIHL Quickstop chain brake for both
experienced and inexperienced chain
saw users.
Please ask your STIHL dealer to
properly match your powerhead with the
appropriate bar / chain combination to
reduce the risk of kickback injury. Green
labeled bars and chains are
recommended for all powerheads.
WARNING
Use of other, non-listed bar / chain
combinations may increase kickback
forces and the risk of kickback injury.
New bar / chain combinations may be
developed after publication of this
literature, which will, in combination with
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
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
