wide work pieces tend to tilt down at the end of the saw table;
this leads to loss of control, jamming of the saw blade and kick-
back.
j) Guide the work piece evenly. Do not bend or twist the work
piece. If the saw blade jams, immediately shut off the power
tool, disconnect the mains plug and eliminate the cause of
jamming. A work piece which has jammed the saw blade can
lead to kickback or to blocking of the motor.
k) Do not remove sawn off material whilst the saw is still oper-
ating. Sawn off material can become fixed between saw blade
and stop rail or in the protecting cover and will pull your fingers
into the saw blade if you attempt to remove the material. Switch
off the saw and wait until the saw blade has come to a complete
standstill before you remove the material.
l) For long sections on work pieces which are thinner than 2
mm, use an additional parallel limit stop that has contact
with the table surface. Thin work pieces can become wedged
under the parallel limit stop and cause kickback.
Kickback – Causes and corresponding safety guidelines
A kickback is the sudden reaction of the work piece due to a catch-
ing, jamming saw blade or because a work piece is cut at an angle
in relation to the saw blade, or if part of the work piece is jammed
between the saw blade and parallel limit stop or other fixed object.
In most cases during a kickback, the work piece is caught by the rear
part of the saw blade, lifted up from the saw table and then flung
towards the operator. Kickback is the result of wrong or faulty use of
the table saw. It can be avoided by using appropriate precautionary
measures, as described in the following.
a. Never stand directly in line with the saw blade. Always keep
to one side of the saw blade where the stop rail is located.
During kickback, the work piece can be flung at high speeds
towards anyone standing in front of and in line with the saw
blade.
b. Never reach over or behind the saw blade to pull on or sup-
port the work piece. Unintentional contact may occur with the
saw blade, or a kickback can cause your fingers to be pulled into
the saw blade.
c. Never hold and press the work piece being sawed against
the rotating saw blade. Pressing the work piece being sawed
against the saw blade will cause jamming and kickback.
d. Align the stop rail in parallel to the saw blade. An unaligned
stop rail will press the work piece against the saw blade and gen-
erate kickback.
e. Use a featherboard when proceeding hidden saw cuts (e.g.
groove, back-gouge or separating in reversal method). The
featherboard allows you to guide the workpiece against
table and longitudinal stop. A featherboard helps you to control
the workpiece in case of kickback.
f. Be especially careful when sawing in out-of-sight areas of
assembled work pieces. A dipping in saw blade can saw into
objects that could cause a kickback.

g. Support large sheets to minimize the risk of kickback
caused by a jammed saw blade. Large sheets can sag under
their own weight. Sheets need to be supported wherever they
extend beyond the table surface.
h. Be particularly careful whilst sawing work pieces which are
twisted, knotted, or warped or do not have a straight edge to
guide them along a mitre stop or stop rail. A warped, knotted
or twisted work piece is unstable and causes misalignment of the
kerf with the saw blade, jamming and kickback.
i. Never saw work pieces that have been stacked or lined up
in succession. The saw blade could catch one or several parts
and cause kickback.
j. If you want to restart a saw whose saw blade is still in a
work piece, centre the saw blade in the sawing gap so that
the saw teeth are not caught in the work piece. If the saw
blade is jammed, it can lift up the work piece and cause a kick-
back when the saw is restarted.
k. Keep the saw blades clean, sharp and sufficiently set. Never
use bent saw blades, or saw blades with cracked or broken
teeth. Sharp and correctly set saw blades minimise jamming,
blocking and kickback.
Safety guidelines for operating table saws
a) Switch off the table saw and disconnect it from the mains
before you remove the table insert, replace the saw blade,
carry out settings on the splitting wedge or the saw blade
guard, and whenever leaving the machine unattended. Pre-
cautions serve to prevent accidents.
b) Never leave an operating table saw unattended. Switch off
the power tool and do not leave until it has reached a com-
plete standstill. An unattended operating saw represents an
uncontrollable risk.
c) Set up the table saw in an area that is level and well lit and
where you can stand securely and keep your balance. The
set-up site must be spacious enough for you to comfortably
handle the size of your work pieces. Disarray, non-lit working
areas and uneven and slippery floors can lead to accidents.
d) Regularly remove chips and saw dust underneath the saw
table and/or from the dust extraction. Accumulated saw dust
is combustible and can self-ignite.
e) Secure the table saw. An improperly secured table saw can
move or fall over
f) Remove adjusting tools, wood scraps etc. from the table saw
before you switch it on. Deflection or possible jams could be
dangerous.
g) Always use the correct size of saw blade and with matching
mounting hole (e.g. diamond-shaped or round). Saw blades
which do not match the assembly parts of the saw will operate
out of centre and will lead to loss of control.
h) Never use damaged or wrong saw blade assembly material
such as e.g. flanges, flat washers, screws or nuts. This saw
blade assembly material was constructed specifically for your
saw, for secure operation and optimal performance.
