Use extra caution when making a "pocket
cut" into existing walls or other blind areas.
The protruding wheel may cut gas or water
pipes, electrical wiring or objects that can
cause kickback.
Safety warnings specific for sanding opera-
tions
When sanding, do not use excessively
oversized sanding disc paper. Follow the
manufacturers' recommendations when
selecting sanding paper. Larger sanding pa-
per extending beyond the sanding pad
presents a laceration hazard and may cause
snagging, tearing of the disc, or kickback.
Safety warnings specific for polishing opera-
tions
Do not allow any loose portion of the pol-
ishing bonnet or its attachment strings to
spin freely. Tuck away or trim any loose at-
tachment strings. Loose and spinning attach-
ment strings can entangle your fingers or snag
on the workpiece.
Safety warnings specific for wire brushing
operations
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.
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
forces.
Additional safety instructions
Use suitable detectors to determine if util-
ity 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 prop-
erty damage or may cause an electric shock.
If the power supply should be discon-
nected, e. g. due to a power outage or pull-
ing the mains plug, release the On/Off
switch and set it to the Off position. This
prevents uncontrolled restarting.
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.
Use a cutting guide when cutting stone.
Without sideward guidance, the cutting disc
can jam and cause kickback.
