 Do not use worn down reinforced wheels from larger
power tools. Wheels intended for larger power tools are
not suitable for the higher speed of a smaller tool and may
burst.
Additional safety warnings specific for abrasive cutting
off operations
 Do not "jam" the cut-off wheel or apply excessive pres-
sure. Do not attempt to make an excessive depth of cut.
Overstressing the wheel increases the loading and suscep-
tibility to twisting or binding of the wheel in the cut and the
possibility of kickback or wheel breakage.
 Do not position your body in line with and behind the ro-
tating wheel. When the wheel, at the point of operation, is
moving away from your body, the possible kickback may
propel the spinning wheel and the power tool directly at you.
 When wheel is binding or when interrupting a cut for
any reason, switch off the power tool and hold the pow-
er tool motionless until the wheel comes to a complete
stop. Never attempt to remove the cut-off wheel from
the cut while the wheel is in motion otherwise kickback
may occur. Investigate and take corrective action to elimi-
nate the cause of wheel binding.
 Do not restart the cutting operation in the workpiece.
Let the wheel reach full speed and carefully re-enter
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 work-
pieces tend to sag under 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 ex-
isting 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 recommendations, when select-
ing sanding paper. Larger sanding paper extending be-
yond the sanding pad presents a laceration hazard and
may cause snagging, tearing of the disc, or kickback.
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 excessive 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 interference of the wire wheel or
brush with the guard. Wire wheel or brush may expand in
diameter due to work load and centrifugal forces.
Additional safety warnings
Wear safety goggles.

 Use suitable detectors to determine if utility 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 explo-
sion. 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 interrupted, e. g., in case of a
power failure or when the mains plug is pulled. This pre-
vents uncontrolled restarting.
 Do not touch grinding and cutting discs before they
have cooled down. The discs can become very hot while
working.
 Secure the workpiece. A workpiece clamped with clamp-
ing devices or in a vice is held more secure than by hand.
Products sold in GB only: Your product is fitted with an
BS 1363/A approved electric plug with internal fuse (ASTA
approved to BS 1362).
If the plug is not suitable for your socket outlets, it should be
cut off and an appropriate plug fitted in its place by an author-
ised customer service agent. The replacement plug should
have the same fuse rating as the original plug.
The severed plug must be disposed of to avoid a possible
shock hazard and should never be inserted into a mains sock-
et elsewhere.
Products sold in AUS and NZ only: Use a residual current de-
vice (RCD) with a rated residual current of 30 mA or less.
Product Description and Specifica-
tions
