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 § 5.12 of ANSI B
175.1-1991. Some low kickback chains
have not been tested with all powerhead
and bar combinations.

) "Low kickback saw chain" is a chain
which has met the kickback perfor-
mance requirements of § 5.12.2.4 of
ANSI B 175.1-1991 (Safety Require-
ments for Gasoline-Powered Chain-
Saws) when tested on a selected repre-
sentative sample of chainsaws below
3.8 cubic inch displacement specified in
ANSI B 175.1-1991.
STIHL offers a variety of bars and
chains.
STIHL reduced kickback bars and low
kickback chains are designed to reduce
the risk of kickback injury. Other chains
are designed to obtain higher cutting
efficiency or sharpening ease but may
result in higher kickback tendency.
STIHL has developed a color code
system to help you identify the STIHL
reduced kickback bars and low kick-
back 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 inch displacement with green
labeled bars and green labeled chains
gives compliance with the computed
kickback angle requirements of ANSI B
175.1-1991 when the products are in
their original condition. Products with
yellow decals or labels are for users with
extraordinary cutting needs and expe-
rience and specialized training for
dealing with kickback.

Please ask your STlHL dealer to properly
match your powerhead with the appro-
priate bar/chain combinations to reduce
the risk of kickback injury. Green labeled
bars and chains are recommended for all
powerheads. See your "STIHL Bar and
Chain Information" leaflet for details.

Use of other, non-listed bar/chain combi-
nations may increase kickback forces
and increase the risk of kickback injury.
New bar/chain combina-tions may be
developed after publication of this litera-
ture, which will, in combina-tion with
certain powerheads, comply with § 5.12
of ANSI B 175.1-1991.
Check with your STI HL dealer for such
combinations.

Do not mount a bow guide on any
STIHL chain saw.
Any chainsaw 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.
