must, in their original condition,
meet a 45° computer derived
kickback angle when equipped with
certain cutting 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.
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.
Devices for reducing the risk of
kickback injury
STIHL recommends the use of the
STIHL Quickstop chain brake on your
power-head with green labeled reduced
kickback bars and low kickback chains.
Compliance with § 5.11 of ANSI B 175.1-
2000
does not automatic-ally mean that
–
in a real life kickback the bar and chain
will rotate at most 45°.
!Warning!
To reduce the risk of injury, stop using
the saw immediately if the chain brake
does not function properly. Take the saw
to your local STIHL Service Center! Do
not use the saw until the problem has
been rectified (see the section "Chain
Brake").
!Warning!
In order for powerheads below 3.8 cubic
inch (62 cm³) displacement to comply
with the computed kickback angle

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.
