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.
