ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing or removing depressed center
wheel (Fig. 3)
Screw the inner flange onto the spindle. Fit the wheel 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. 4)
To remove the wheel, follow the installation procedure in
reverse.
WARNING:
Only actuate the shaft lock when the spindle is not
moving.
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.
• Continued use of a worn-out wheel may result in wheel
explosion and serious personal injury. Depressed
center wheel should not be used after it has been worn
down to 75 mm in diameter. Use of the wheel after this
point is unsafe and it should be removed from service
and rendered unusable by intentional destruction.
(Fig. 5)
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.
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. 6)
Screw 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.
WARNING:
Only actuate the shaft lock when the spindle is not
moving.
Base (optional accessory)
When you wish to use a diamond wheel, install the base
on the tool. Loosen the screw on the wheel cover with a
screwdriver. Move the wheel cover to a convenient
position and secure it by tightening the screw. (Fig. 7)
8
Install the base on the wheel cover using the hole in the
wheel cover. (Fig. 8)
Secure the base in place by tightening the wing nut.
(Fig. 9)
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.
Replacing carbon brushes (Fig. 10)
Remove and check the carbon brushes regularly. Replace
when they wear down to the limit mark. 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. 11)
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.
