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
property 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.
