the wheel guard band aligned with the notch on the
bearing box. Then rotate the wheel guard around 180°.
Fasten it with the screw after pulling lever in the direction
of the arrow for the working purpose. The setting angle of
the wheel guard can be adjusted with the lever.
To remove wheel guard, follow the installation procedure
in reverse.
Installing or removing depressed center
grinding wheel/Multi-disc (accessory)
(Fig. 10)
Mount the inner flange onto the spindle. Fit the wheel/disc
on the inner flange and screw the lock nut onto the
spindle.
To tighten the lock nut, press the shaft lock firmly so that
the spindle cannot revolve, then use the lock nut wrench
and securely tighten clockwise. (Fig. 11)
To remove the wheel, follow the installation procedure in
reverse.
Installing or removing diamond wheel
(optional accessory)
CAUTION:
• Make sure that the arrow on the tool should point in the
same direction as the arrow on the diamond wheel.
(Fig. 12)
Mount the inner flange onto the spindle. Fit the diamond
wheel on over the inner flange and screw the lock nut onto
the spindle. Notice that flat side of the lock nut should face
the diamond wheel in case the diamond wheel is used.
Installing or removing dust cover
attachment (Optional accessory)
WARNING:
• Always be sure that the tool is switched off and
unplugged before installing or removing the dust cover
attachment. Failure to do so causes damage to the tool
or a personal injury.
There are three types of dust cover attachment and each
is used in one of different positions. (Fig. 13 - 15)
Place the dust cover attachment so that the side of the
dust cover attachment with the marking (A, B or C) faces
towards the tool head. Snap the pins of the dust cover
attachment in the vent. (Fig. 16)
Dust cover attachment can be removed by hand.
NOTE:
• Clean out the dust cover attachment when it is clogged
with dust or foreign matters. Continuing operation with
a clogged dust cover attachment will damage the tool.
OPERATION
WARNING:
• It should never be necessary to force the tool. The
weight of the tool applies adequate pressure. Forcing
and excessive pressure could cause dangerous wheel
breakage.
• ALWAYS replace wheel if tool is dropped while
grinding.
• NEVER bang or hit grinding disc or wheel onto work.
• 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:
• After operation, always switch off the tool and wait until
the wheel has come to a complete stop before putting
the tool down.
Grinding and sanding operation
ALWAYS hold the tool firmly with one hand on housing
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. (Fig. 17)
Operation with diamond wheel
(accessory)
WARNING:
• Forcing and exerting excessive pressure or allowing
the wheel to bend, pinch or twist in the cut can cause
overheating of the motor and dangerous kickback of
the tool.
CAUTION:
• After cutting operation, make sure that the diamond
wheel stops revolving completely. Then, place the tool.
It is dangerous to place the tool before turning off the
tool. If there is dust or dirt around the tool, the tool may
suck them in.
Be sure that the wheel does not contact the workpiece.
Turn the tool on and hold the tool firmly. Wait until the
wheel attains full speed. Now simply move the tool
forward over the workpiece surface, keeping it flat and
advancing smoothly until the cutting is completed.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance. (Fig. 18)
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.
To maintain product SAFETY and RELIABILITY, repairs,
carbon brush inspection and replacement, any other
maintenance or adjustment should be performed by
Makita Authorized Service Centers, always using Makita
replacement parts.
