Safety warnings specific for sanding op-
erations
f Do not use excessively oversized sanding
disc paper. Follow manufacturers recom-
mendations, when selecting sanding paper.
Larger sanding paper extending beyond the
sanding pad presents a laceration hazard and
may cause snagging, tearing of the disc, or
kickback.
Safety warnings specific for wire brush-
ing operations
f Be aware that wire bristles are thrown by
the brush even during ordinary operation.
Do not overstress the wires by applying ex-
cessive load to the brush. The wire bristles
can easily penetrate light clothing and/or
skin.
f If the use of a guard is recommended for
wire brushing, do not allow any interfer-
ence of the wire wheel or brush with the
guard. Wire wheel or brush may expand in di-
ameter due to work load and centrifugal forc-
es.
Additional safety warnings
Wear safety goggles.
f Use suitable detectors to determine if utili-
ty lines are hidden in the work area or call
the local utility company for assistance.
Contact 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.
f Release the On/Off switch and set it to the
off position when the power supply is inter-
rupted, e. g., in case of a power failure or
when the mains plug is pulled. This prevents
uncontrolled restarting.
f When working stone, use dust extraction.
The vacuum cleaner must be approved for
the extraction of stone dust. Using this
equipment reduces dust-related hazards.
f Use a cutting guide when cutting stone.
Without sideward guidance, the cutting disc
can jam and cause kickback.
f When working with the machine, always
hold it firmly with both hands and provide
for a secure stance. The power tool is guided
more secure with both hands.
f Secure the workpiece. A workpiece clamped
with clamping devices or in a vice is held
more secure than by hand.
f Keep your workplace clean. Blends of mate-
rials are particularly dangerous. Dust from
light alloys can burn or explode.
f Never use the machine with a damaged ca-
ble. Do not touch the damaged cable and
pull the mains plug when the cable is dam-
aged while working. Damaged cables in-
crease the risk of an electric shock.
