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.
To ensure that the guide wedge functions proper-
ly, 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.
b. Do not operate the saw if the guide wedge is
bent. Even the slightest problem can cause the
protective cover 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.
Ensure that enclosed spaces are ade-
quately ventilated and, if necessary, connect a mo-
bile dust extractor.

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
workpiece,
– Touching live parts when the casing is opened
and the mains plug is in the socket,
– the flying off of parts,
– the flying off of machine parts from a damaged
machine,
– noise emission,
– dust emission.

Aluminium processing

When sawing aluminium, the following mea-
sures must be taken for safety reasons:
– Install an upstream residual-current circuit
breaker (FIG, PRCD).
– Connect the machine to a suitable dust extractor.
– Regularly remove dust deposits from the motor
housing.
– Use an aluminium saw blade.
– Close the viewing window/chipguard.
Wear protective goggles.
– When sawing panels, they must be lubricated
with paraffin but thin-walled profiles (up to 3
mm) can be sawed without lubrication.
