During the break-in period with a new wheel, do not work
the grinder in the B direction or it will cut into the work-
piece. Once the edge of the wheel has been rounded off
by use, the wheel may be worked in both A and B direc-
tion.
Operation with wire cup brush
(optional accessory)
CAUTION:
•Check operation of brush by running tool with no
load, insuring that no one is in front of or in line with
brush.
•Do not use brush that is damaged, or which is out
of balance. Use of damaged brush could increase
potential for injury from contact with broken brush
wires.
Unplug tool and place it upside down allowing easy
access to spindle. Remove any accessories on spindle.
Mount urethane washer then thread wire cup brush onto
spindle and tighten with supplied wrench. When using
brush, avoid applying too much pressure which causes
over bending of wires, leading to premature breakage.
NOTE:
•When using wire cup brush, mount urethane
washer to the spindle. It will make it easier to
remove wire cup brush.
Operation with wire wheel brush
(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
pressure which causes over bending of wires, leading to

MAINTENANCE
CAUTION:
•Always be sure that the tool is switched off and
unplugged before attempting to perform inspection
or maintenance.
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.
Replacing carbon brushes
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.
