down on bench or floor. An unprotected,
coasting blade will cause the saw to walk
backwards, cutting whatever is in its path.
Be aware of the time it takes for the blade
to stop after switch is released.
Function of the guide wedge [1-5]
Use the correct saw blade for the guide
a.
wedge, where possible. The function of the
guide wedge is restricted if using saw
blades with a thicker blade core. To en­
sure that the guide wedge functions prop­
erly, 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 in­
creased 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 instal­
–
led in a work bench. The electric power
tool may become unsafe and cause serious
accidents if installed in benches from other
manufacturers or self-manufactured work
benches.
Never place your hands into the chip ejec­
–
tor. You may injure yourself on rotating
parts.
– Use suitable detectors to determine if util­
ity lines are hidden in the work area or
call the local utility company for assis­
tance. Aontact with electric lines can lead
to fire and electric shock. Damaging a gas
line can lead to explosion. Penetrating 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 dur­
ing your work (e.g. paint containing lead,
certain types of wood and metal). Inhaling
or coming into contact with this dust may
represent a hazard for operating personnel
or persons in the vicinity. Comply with the
safety regulations that apply in your coun­
try.
Wear a P2 dust mask to protect your
health.

Ensure that enclosed spaces are adequately
ventilated and, if necessary, connect a mobile
dust extractor.

Residual risks

In spite of compliance with all relevant design
regulations, hazzards while operating the ma­
chine 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 dam­
aged machine,
– noise emission,
– dust emission.

Aluminium processing

When sawing aluminium, the following
measures must be taken for safety reasons:
– Install an upstream residual-current circuit
breaker (FIG, PRCD).
– Connect the machine to a suitable dust ex­
tractor.
– 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 lubrica­
ted with paraffin but thin-walled profiles
(up to 3 mm) can be sawed without lubrica­
tion.
