During the break-in period with a new wheel, do not work
the grinder in the B direction or it will cut into the
workpiece. Once the edge of the wheel has been rounded
off by use, the wheel may be worked in both A and B
direction.
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. (Fig. 9)
Unplug tool and place it upside down allowing easy
access to spindle. Remove any accessories on spindle.
Mount 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.
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. (Fig. 10)
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.
Operation with abrasive cut-off/diamond
wheel (optional accessory)
WARNING:
• When using an abrasive cut-off/diamond wheel, be
sure to use only the special wheel guard designed for
use with cut-off wheels.
• NEVER use cut-off wheel for side grinding.
• Do not "jam" the wheel or apply excessive pressure. Do
not attempt to make an excessive depth of cut.
Overstressing the wheel increases the loading and
susceptibility to twisting or binding of the wheel in the
cut and the possibility of kickback, wheel breakage and
overheating of the motor may occur.
• Do not start the cutting operation in the workpiece. Let
the wheel reach full speed and carefully enter into the
cut moving the tool forward over the workpiece surface.

Mount the inner flange onto the spindle. Fit the wheel/disc
on the inner flange and screw the lock nut onto the
spindle. (Fig. 11)
When installing a diamond wheel with its 7 mm or thicker
wheel body, mount the lock nut with its pilot circular part
(protrusion) for wheel bore facing the wheel.

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 (Fig. 14)
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. (Fig. 15)
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers, always
using Makita replacement parts.
The wheel may bind, walk up or kickback if the power
