The greater the force of the kickback
reaction, the more difficult it becomes for
the operator to control the saw. Many
factors influence the occurrence and
force of the kickback reaction. These
include chain speed, the speed at which
the bar and chain contact the object, the
angle of contact, the condition of the
chain and other factors.

The type of bar and saw chain you use
is an important factor in the occurrence
and force of the kickback reaction. Some
STIHL bar and chain types are designed
to reduce kickback forces. STIHL

Warning!
Devices for reducing the risk of
kickback injury
The computer derived angles of § 5.11
of ANSI B 175.1-2000 may bear no rela-
tionship to actual kickback bar rotation
angles that may occur in real life cutting
situations.
recommends the use of reduced
kickback bars and low kickback chains.
STIHL recommends the use of the
STIHL Quickstop chain brake on your
powerhead with green labeled reduced
kickback bars and low kickback chains.
ANSI B 175.1-2000 chain saw
kickback standard
In addition, features designed to reduce
kickback injuries may lose some of their
effectiveness when they are no longer in
their original condition, especially if they
have been improperly maintained.
Compliance with § 5.11 of ANSI
B 175.1-2000 does not automatically
mean that in a real life kickback the bar
and chain will rotate at most 45°.
§
sets certain performance and design
criteria related to chain saw kickback.

Warning!
To reduce the risk of injury, never use a
saw if the chain brake does not function
properly. Take the saw to your local
STIHL servicing dealer. Do not use the
saw until the problem has been rectified.
To comply with § 5.11 of ANSI
B 175.1-2000:
a)
Saws with a displacement of less
than 3.8 cubic inches (62 cm³)
–
must, in their original condition,
meet a 45° computer derived
kickback angle when equipped with
certain cutting attachments,
STIHL Quickstop chain brake
STIHL has developed a chain stopping
system designed to reduce the risk of
injury in certain kickback situations. It is
called a Quickstop chain brake. The
Quickstop chain brake is standard
equipment on your STIHL chain saw.
Warning!
In order for powerheads below 3.8 cubic
inches (62 cm³) displacement to comply
with the computed kickback angle
requirements of § 5.11 of ANSI
B 175.1-2000 use only the following cut-
ting attachments:
–
and must be equipped with at least
two devices to reduce the risk of
kickback injury, such as a chain
brake, low kickback chain, reduced
kickback bar, etc.
b)
Saws with a displacement of
3.8
cubic inches (62 cm³) and
above
