Causes of kickbacks and related safety
information
A kickback is the sudden reaction of the
workpiece resulting from a caught, jammed
saw blade or a cut performed at an angle
in the workpiece relative to the saw blade,
or when part of the workpiece becomes
jammed between the saw blade and the
parallel stop or any other fi xed object.
In most cases when kickback occurs, the
workpiece gets caught by the rear section of
the saw blade, gets lifted from the saw table
and thrown in the direction of the operator.
Kickback is the result of the bench-type cir-
cular saw being used incorrectly or wrongly.
It can be prevented by suitable precautions,
as described below.
a) Never position yourself in a direct
line with the saw blade. Always
stand to the side of the saw blade,
at the side with the stop rail.
In the
event of kickback, the workpiece can be
thrown at high speed towards persons
who are standing in line with the saw
blade.
b) Never reach into or behind the saw
blade to pull or support the workpie-
ce.
This could lead to accidental contact
with the saw blade, or kickback could
cause your fi ngers to be drawn into the
saw blade.
c) Never hold and press a workpiece
against the rotating saw blade when
you want to saw the workpiece.
Pres-
sing the workpiece against the saw bla-
de when sawing workpiece will result in
jamming and kickback.
d) Align the stop rail parallel to the
saw blade.
If the stop rail is not pro-
perly aligned, the workpiece will press
against the saw blade and cause kick-
back.
e) Do not use this saw to cut rebates or
grooves.
For design reasons, the saw is
not suitable for such work. The splitter
must never be removed, because it pre-
vents jamming and kickbacks.
f) Be particularly careful when sawing
in areas into which you cannot see on
workpieces which have been joined
together.
The plunge-cutting saw
blade may saw into objects which could
cause kickback.
g) Support large panels to reduce the
risk of a kickback by a jammed saw
blade.
Large panels may sag under
their own weight. Panels must be pro-
vided with support at all points where
they project over the table surface.
h) Do not work on any workpieces
which are twisted, knotted or war-
