Stihl TS 400 - Reducing Kickback Injury Risk

English / USA
Reducing the Risk of Kickback Injury
!Warning!
To reduce the risk of kickback injury,
avoid cutting with the upper quadrant of
the wheel where possible. Be especially
cautious for a pinching of the wheel in
this area, which can cause severe
reactive forces in a rotational kickback
motion.
Be alert to potential movement of the
work piece or anything else that could
cause the cut to close and pinch the
wheel. In order to reduce the risk of
pinching, support the work piece in such
a way that the cut remains open during
the cutting process and when the cut is
finished (see illustration). Never make a
cut that results in a binding of the wheel.
!Warning!
Be particularly alert when cutting a work
piece that, if not properly supported, can
sag upon completion of the cut, creating
a pinch not where you are actually
cutting but, rather, at or near the top of
the work piece (see illustration). If that
pinch is in the upper quadrant of the
abrasive wheel, kickback can result.
!Warning!
Use only cutting attachments authorized
by STIHL. Never use chipped abrasive
wheels, circular saw blades, carbide-
tipped blades, rescue blades or wood-
cutting or toothed blades of any nature
on a cut-off machine. The use of such
wheels or blades will greatly increase
the risk of loss of control and severe
personal injury or death from reactive
forces, since the chipped section of an
abrasive wheel, or the teeth of a saw
blade may catch in the material being
cut and generate substantially greater
reactive forces, including rotational
kickback.
Cut-off machines are designed for use
with abrasive wheels in good condition
only. Machines designed for use with
wood-cutting or other toothed blades
use different types of guarding systems
which provide the protection necessary
for those types of blades. Machines,
such as a cut-off machine, that are
designed for use with abrasive wheels,
require a different guarding system,
which is not designed to provide
protection against all dangers presented
by circular saw blades, carbide-tipped
blades, rescue blades or wood-cutting or
toothed blades of any nature.
