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 oper-
ator. Kickback is the result of incorrect or deficient
use of the circular table saw. It can be prevented by
suitable precautionary measures, as described in the
following.
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 to-
wards 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 kick-
back 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 saw-
ing 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 workpiece
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 ta-
ble and stop rail. Using a thrust collar, you are
able to better control the workpiece in the event
of kickback.
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
overhang 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 work-
piece is unstable and results in incorrect align-
ment 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
result 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 remov-
ing the table insert, changing the saw blade,
implementing settings on the riving knife or
the saw blade protective cover, and if the ma-
chine is left unattended. Precautionary meas-
ures serve to prevent accidents.
b) Never leave the circular table saw running un-
attended. 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.
c) Set up the circular table saw in a location that
is level and well ventilated, and where it can
stand safely and remain balanced. The instal-
lation site must provide sufficient space for
easily handling the size of your workpieces.
Disorganised and unlit working areas, and une-
ven, slippery floors may lead to accidents.
d) Regularly remove chips and sawdust from be-
neath the saw table and/or from the dust ex-
traction system. Accumulated sawdust is flam-
mable and can self-ignite.
e) Secure the circular table saw. If a circular ta-
ble saw is not secured correctly, it can move or
topple.
f) Remove the adjustment tools, wood residues,
etc. from the circular table saw before switch-
ing it on. Deflections and possible jams could be
dangerous.
g) Always use the right size of saw blade
and an appropriate location hole (e.g. dia-
mond-shaped or round). Saw blades that do not
