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.
Warning!
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.
A dull or improperly sharpened chain
may reduce or negate the effects of the
design features intended to reduce kick-
back 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.
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
Low kickback chain
inexperienced chain saw users.
Some types of saw chain have specially
designed components to reduce the
force of nose contact kickback. STIHL
has developed low kickback chain for
your powerhead.
Reduced kickback bars
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
STIHL green labeled reduced kickback
bars are designed to reduce the risk of
kickback injury when used with STIHL
green labeled low kickback chains.
"Low kickback saw chain" is a chain
which has met the kickback
recommended for all powerheads.
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!
Warning!
When used with other, more aggressive
chains, these bars may be less effective
in reducing kickback.
Use of other, non-listed bar/chain com-
binations may increase kickback forces
and the risk of kickback injury. New
bar/chain combinations may be devel-
oped 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.
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.
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!
Reduced kickback bars and low kick-
back chains do not prevent kickback,
but they are designed to reduce the risk
of kickback injury. They are available
from your STIHL dealer.
To avoid kickback
The best protection from personal injury
that may result from kickback is to avoid
kickback situations:
