•
Avoid bouncing and snagging the wheel,
especially when working corners, sharp edges etc.
This can cause loss of control and kickback.
•
NEVER use tool with wood cutting blades and
other sawblades. Such blades when used on a
grinder frequently kick and cause loss of control
leading to personal injury.
CAUTION:
•
Never switch on the tool when it is in contact with
the workpiece, it may cause an injury to operator.
•
Always wear safety goggles or a face shield during
operation.
•
After operation, always switch off the tool and wait
until the wheel has come to a complete stop
before putting the tool down.
Grinding operation
Fig.7
ALWAYS hold the tool firmly with one hand on rear
handle and the other on the side handle. Turn the tool
on and then apply the wheel or disc to the workpiece.
In general, keep the edge of the wheel or disc at an
angle of about 15 degrees to the workpiece surface.
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 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. The wheel may bind, walk up
or kickback if the power tool is started in the
workpiece.
•
During cutting operations, never change the angle
of the wheel. Placing side pressure on the cut-off
wheel (as in grinding) will cause the wheel to crack
and break, causing serious personal injury.
•
A diamond wheel shall be operated perpendicular
to the material being cut.
Mount the inner flange onto the spindle. Fit the
wheel/disc on the inner flange and screw the lock nut
onto the spindle.

MAINTENANCE
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.
Fig.10
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.11
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.

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.
