i) Support long and/or wide workpieces at the
rear and/or side of the saw table, so that they
remain horizontal. Long and/or wide workpieces
tend to tilt at the edge of the saw table; this leads
to a loss of control, jamming of the saw blade and
kickback.
j) Guide the workpiece steadily and evenly. Do
not bend or twist the workpiece. If the saw
blade jams, switch off the electric tool imme-
diately, unplug the mains plug and remedy the
cause of the jam. If the saw blade is jammed by
the workpiece, this can lead to kickback or block
the motor.
k) Do not remove partially sawn material whilst
the saw is running. Partially sawn material can
stick between the saw blade and stop rail or in the
protective cover, and may draw your fingers into
the saw blade during removal. Switch the saw off
and wait until the saw blade has come to a stand-
still, before removing the material.
l) For longitudinal cuts on workpieces that are
thinner than 2 mm, use an additional parallel
stop that is in contact with the table surface.
Thin workpieces can wedge under the parallel
stop and lead to kickback.
Kickback - causes and corresponding safety in-
structions
Kickback is a sudden reaction of the workpiece to a
catching or jamming saw blade, or a cut created in
the workpiece at an angle to the saw blade, or if part
of the workpiece becomes jammed between the saw
blade and the parallel stop, or another stationary ob-
ject.
In the majority of cases, with kickback the workpiece
is caught by the rear part of the saw blade, lifted off
the saw table and thrust in the direction of the opera-
tor. Kickback is the result of incorrect or deficient use
of the circular table saw. It can be prevented by suit-
able precautionary measures, as described in the fol-
lowing.
a) Never stand directly in line with the saw blade.
Always stand at the side of the saw blade on
which the stop rail is located. With kickback, the
workpiece may be thrust at high speed towards
those persons who stand in front of, or in line with
the saw blade.
b) Never reach over or behind the saw blade to
pull or support the workpiece. This can result in
accidental contact with the saw blade, or kickback
can lead to your fingers being drawn into the saw
blade.
c) Never hold and push the workpiece against the
turning saw blade during sawing. Pushing the
workpiece against the saw blade during sawing
will lead to jamming and kickback.

d) Align the stop rail parallel to the saw blade.
A stop rail that is not aligned will push the work-
piece against the saw blade and create kickback.
e) With concealed saw cuts (e.g. folds, grooves
or slits in the turning process), use a thrust
collar to guide the workpiece against the table
and stop rail. Using a thrust collar, you are able
to better control the workpiece in the event of kick-
back.
f) Apply particular caution when sawing assem-
bled workpieces in areas that are not visible.
The plunging saw blade can saw into objects that
could cause a kickback.
g) Support large panels, in order to avoid the risk
of kickback due to a jammed saw blade. Large
panels may bend under their own weight. Panels
must be supported in all areas where they over-
hang the table surface.
h) Apply particular caution when sawing work-
pieces that are twisted, knotted or warped, or
that do not have a straight edge that can be
used to guide them with a mitre stop or along a
stop rail. A twisted, knotted or warped workpiece
is unstable and results in incorrect alignment of the
kerf with the saw blade, jamming and kickback.
i) Never saw multiple workpieces stacked on top
of each other, or one behind the other. The saw
blade could engage in one or more parts and re-
sult in kickback.
j) If you wish to restart a saw, the saw blade of
which is inserted in a workpiece, centre the
saw blade in the sawing gap so that the saw
teeth are not hooked in the workpiece. If the saw blade is jammed, it can lift the workpiece and
cause kickback when the saw is restarted.
k) Always keep saw blades clean, sharp and suf-
ficiently set. Never use warped saw blades
or saw blades with cracked or broken teeth.
Sharp and correctly set saw blades minimise jam-
ming, blocking and kickback.
Safety instructions for the operation of circular
table saws
a) Switch off the circular table saw and discon-
nect it from the power supply before removing
the table insert, changing the saw blade, imple-
menting settings on the riving knife or the saw
blade protective cover, and if the machine is
left unattended. Precautionary measures serve
to prevent accidents.
b) Never leave the circular table saw running
unattended. Switch off the electric tool and
do not leave it until it has come to a complete
standstill. An unattended running saw poses an
uncontrolled risk.
