1. ANSI B 175.1-2011
STIHL offers chain saw cutting
attachments that comply with the
performance, design, labeling and
information requirements of the
ANSI kickback standard. STIHL has
also made it easy for you to
understand and to comply with that
standard.
ANSI is the abbreviation for the
American National Standards
Institute. The first ANSI standard for
chain saws was developed in 1979,
and the kickback requirements
where first added to the standard in
1985. Although the standard is
voluntary in theory, it must be
considered as mandatory in
practice. If a dealer sells a non-
complying product or fails to
adequately warn the customer while
purchasing non-complying
products, the dealer may increase
the risk of kickback injury to his
customer.
1.1 B 175.1-2011
REQUIREMENTS
ANSI Performance and Design
Requirements
Section 5.11of the ANSI B 175.1-
2011 standard establishes certain
performance and design criteria
related to chain saw kickback.
To comply with section 5.11 of ANSI
B 175.1-2011:
a. saws with a displacement of less
than 3.8 cubic inches
: must, in their original condition,
meet a 45 degree computer-
derived kickback angle or the
moving chain shall be stopped
before the chain saw meets the
45 degree computed kickback
angle
: and must be equipped with at
least two devices to reduce the
risk of a kickback injury, such as
a chain brake, low kickback
chain, reduced kickback bar, etc.
Chain and Bar Manual
b. saws with a displacement of 3.8
cubic inches and above.
: 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 October 14, 1994 edition of the
UL 1662 standard establishes
similar performance and design
criteria for electric chain saws.
1.2 ANSI LABELING AND
INFORMATION
REQUIREMENTS
In addition to the performance and
design requirements, the standard
also includes detailed requirements
for labeling powerheads and
replacement chains.
The standard requires that you, the
dealer, give to the customer
information on how to achieve
compliance. It also directs that
specific warnings be included in the
instruction manual.
1.3 HOW STIHL HELPS YOU
COMPLY WITH THE
STANDARD
STIHL's Color Code System
STIHL has developed a color code
system to help make it easy for you
to:
: comply with the ANSI B 175.1-
2011 chain saw kickback
standard;
: know the difference between
powerheads with a displacement
of less than 3.8 cubic inches and
powerheads with a displacement
of 3.8 cubic inches and above;
: identify the STIHL bars and
STIHL chains with kickback
reduction characteristics.
This color code system uses the
colors green and yellow.
Green marks the products ("green
family") which are designed to
reduce the risk of kickback injury
and to comply with the ANSI B
175.1 kickback standard. These
products are recommended for both
experienced and inexperienced
chain saw users.
CAUTION
Products marked yellow indicate an
increased risk of kickback injury and
are for use only by persons with
extraordinary cutting needs and
experience and specialized training
for dealing with kickback.
The STIHL color code system
includes powerheads, replacement
chains and guide bars.
