(optional accessory)
CAUTION:
• Check operation of wire wheel brush by running tool with
no load, insuring that no one is in front of or in line with
the wire wheel brush.
• Do not use wire wheel brush that is damaged, or which
is out of balance. Use of damaged wire wheel brush
could increase potential for injury from contact with
broken wires.
• ALWAYS use guard with wire wheel brushes, assuring
diameter of wheel fits inside guard. Wheel can shatter
during use and guard helps to reduce chances of
personal injury.
Unplug tool and place it upside down allowing easy access
to spindle. Remove any accessories on spindle. Thread wire
wheel brush onto spindle and tighten with the wrenches.
When using wire wheel brush, avoid applying too much pres-
sure which causes over bending of wires, leading to prema-
ture breakage.
CAUTION:
• Always be sure that the tool is switched off and

The tool and its air vents have to be kept clean. Regularly
clean the tool's air vents or whenever the vents start to
become obstructed.
