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.
b)
–
saws with a displacement of 3.8
cubic inches and above
!
Warning!
In order for powerheads below 3.8 cubic
inch displacement to comply with the
computed kickback angle requirements
of § 5.11 of ANSI B 175.1-2000 use only
the following cutting attachments:
must be equipped with at least one
device designed to reduce the risk
of kickback injury such as a chain
brake, low kickback chain, reduced
kickback bar, etc.
The computer derived angles for saws
below 3.8 cubic inch displacement are
measured by applying a computer
program to test results from a kickback
test machine.
–
bar and chain combinations listed
as complying in the “Specifications”
section of the owner's manual or
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

combinations marked in
accordance with the standard for
use on the powerhead or

Warning!
recommends the use of reduced
kickback bars and low kickback chains.
The computer derived angles of § 5.11
of ANSI B 175.1-2000 may bear no
relationship to actual kickback bar
rotation angles that may occur in real life
cutting situations.

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.
Section 5.11 of ANSI standard
B 175.1-2000 sets certain performance
and design criteria related to chainsaw
kickback.
To comply with section 5.11 of ANSI
B 175.1-2000:
Compliance with § 5.11 of ANSI B 175.1-
2000
in a real life kickback the bar and chain
will rotate at most 45°.
does not automatically mean that
a)
saws with a displacement of less
than 3.8 cubic inches
–
must, in their original condition,
meet a 45° computer derived
kickback angle when equipped with
certain cutting attachments.
1) “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 (Safety
Requirements for Gasoline-Powered
Chain Saws) when tested in its original
condition on a selected representative
sample of chainsaws below 3.8 cubic
inch displacement specified in ANSI B
175.1-2000.
–
and must be equipped with at least
two devices to reduce the risk of
kickback injury, such as a
chainbrake, low kickback chain,
reduced kickback bar, etc.
