Safety Warnings Specific for Wire
Brushing Operations
a) 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.
b) 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 and centrifugal forces.
Additional Safety Rules for Grinders
• Threaded mounting of accessories must match
the grinder spindle thread. For accessories
mounted by flanges, the arbor hole of the
accessory must fit the locating diameter of
the flange. Accessories that do not match the
mounting hardware of the power tool will run
out of balance, vibrate excessively and may
cause loss of control.
• The grinding surface of the centre depressed
wheels must be mounted below the plane of
the guard lip. An improperly mounted wheel
that projects through the plane of the guard lip
cannot be adequately protected.
• Do not use Type 11 (flaring cup) wheels on
this tool. Using inappropriate accessories can
result in injury.
• Always use side handle. Tighten the handle
securely. The side handle should always be
used to maintain control of the tool at all times.
Residual Risks
In spite of the application of the relevant safety
regulations and the implementation of safety
devices, certain residual risks cannot be avoided.
These are:
– Impairment of hearing.
– Risk of personal injury due to flying particles.
– Risk of burns due to accessories becoming hot
during operation.
– Risk of personal injury due to prolonged use.
– Risk of dust from hazardous substances.
