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
pressure which causes over bending of wires, leading to
premature breakage.

CAUTION:
Always be sure that the tool is switched off and
•
unplugged before attempting to perform inspection
or maintenance.
Never use gasoline, benzine, thinner, alcohol or
•
the like. Discoloration, deformation or cracks may
result.
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.

When the resin insulating tip inside the carbon brush is
exposed to contact the commutator, it will automatically
shut off the motor. When this occurs, both carbon
brushes should be replaced. Keep the carbon brushes
clean and free to slip in the holders. Both carbon
brushes should be replaced at the same time. Use only
identical carbon brushes.
Use a screwdriver to remove the brush holder caps.
Take out the worn carbon brushes, insert the new ones
and secure the brush holder caps.
