the saw blade in the kerf so that the saw teeth
are not engaged into the material. If a saw blade
binds, it may walk up or kickback from the work-
piece as the saw is restarted.
d. Support large panels to minimise the risk of
blade pinching and kickback. Large panels tend
to sag under their own weight. Supports must be
placed under the panel on both sides, near the
line of cut and near the edge of the panel.
e. Do not use dull or damaged blades. Unsharp-
ened or improperly set blades produce narrow
kerf causing excessive friction, blade binding and
kickback.
f. Blade depth and bevel adjusting locking levers
must be tight and secure before making the cut.
If blade adjustment shifts while cutting, it may
cause binding and kickback.
g. Use extra caution when sawing into existing
walls or other blind areas. The protruding blade
may cut objects that can cause kickback.
Function of the lower guard
a. Before using the machine, check whether the
lower guard closes correctly. Do not use the saw
if the lower guard does not move freely or close
immediately. Never clamp or secure the lower
guard in an open position. If the saw is dropped
or accidentally falls to the ground, the lower
guard may become bent. Open the guard using
the retraction lever and make sure that the guard
can move freely and does not make contact with
the saw blade or other components at every cut-
ting angle and depth.
b. Check the function of the springs for the lower
guard. If the lower guard or springs show any
signs of a defect, have the saw serviced before
using it again. Damaged parts, sticky deposits or
accumulated chips may result in delayed opera-
tion of the lower guard.
c. Open the lower guard by hand only for special
cuts, such as plunge cuts and angled cuts. Open
the lower guard using the retractor lever and
release it as soon as the saw blade plunges into
the workpiece. The lower guard should work au-
tomatically for all other sawing work.
d. Make sure the lower guard is covering the saw
blade before placing the saw on a worktop or on
the ground. An unprotected, rotating saw blade
placed on any surface will move the saw against
the cutting direction and cut anything in its path.
Therefore, always make sure the saw blade has
stopped rotating.
Function of the guide wedge [1-5]
a. Use the correct saw blade for the guide wedge,
18
where possible. The function of the guide wedge
is restricted if using saw blades with a thicker
blade core. To ensure that the guide wedge func-
tions properly, make sure the blade core of the
saw blade is thinner than the guide wedge and
that the tooth width is greater than the thickness
of the guide wedge. Expect increased risk of
kickback when using a thicker saw blade.
b. Do not operate the saw if the guide wedge is
bent. Even the slightest problem can cause the
guard to close more slowly.
Further safety instructions
– This electric power tool cannot be installed in a
work bench. The electric power tool may become
unsafe and cause serious accidents if installed in
benches from other manufacturers or self-man-
ufactured work benches.
– Never place your hands into the chip ejector. You
may injure yourself on rotating parts.
– Use suitable detectors to determine if utility
lines are hidden in the work area or call the lo-
cal utility company for assistance. Contact with
electric lines can lead to fire and electric shock.
Damaging a gas line can lead to explosion. Pene-
trating a water line causes property damage or
may cause an electric shock.
– Wait until the power tool stops completely until
placing it down. The tool can become entangled
and lead to a loss of control of the power tool.
– Do not use the machine for overhead work.
– Harmful/toxic dust may be produced during
your work (e.g. paint containing lead, certain
types of wood and metal). Inhaling or coming
into contact with this dust may represent a haz-
ard for operating personnel or persons in the vi-
cinity. Comply with the safety regulations that
apply in your country.
Wear a P2 dust mask to protect your
health.

Residual risks

In spite of compliance with all relevant design reg-
ulations, hazzards while operating the machine still
occur e.g.:
– Touching the saw blade in the area of the front
opening below the saw table,
– Touching the parts of the saw blade that protrude
below the saw table while cutting,
– Touching rotating parts from left and right sides:
saw blade, clamping flange, flange screw.,
– Kickback of machine due to jamming in the
