When wheel is binding or when interrupting
a cut for any reason, switch off the power
tool and hold the power tool motionless un-
til the wheel comes to a complete stop. Nev-
er attempt to remove the cut-off wheel from
the cut while the wheel is in motion other-
wise kickback may occur. Investigate and
take corrective action to eliminate the cause
of wheel binding.
Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed
and carefully reenter the cut. The wheel may
bind, walk up or kickback if the power tool is
restarted in the workpiece.
Support panels or any oversized workpiece
to minimize the risk of wheel pinching and
kickback. Large workpieces tend to sag un-
der their own weight. Supports must be
placed under the workpiece near the line of
cut and near the edge of the workpiece on
both sides of the wheel.
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
operations
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 polishing
operations
Do not allow any loose portion of the polish-
ing bonnet or its attachment strings to spin
freely. Tuck away or trim any loose attach-
ment 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 forc-
es.
Additional safety warnings
Wear safety goggles.
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.
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.
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.
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.
Secure the workpiece. A workpiece clamped
with clamping devices or in a vice is held
more secure than by hand.
