OPERATING INSTRUCTIONS
Installing the wheel guard (Fig. 1 & 2)
Mount the wheel guard with the tab on the wheel
guard band aligned with the notch on the bearing box.
Then rotate the wheel guard 180° clockwise (for
9526NB) or counterclockwise (for 9527NB and
9528NB). Be sure to tighten the screws securely.
Installing side grip (auxiliary handle) (Fig. 3)
For 9527NB and 9528NB only
Screw the side grip on the tool securely. The side grip
can be installed on either side of the tool, whichever is
convenient.
Installing or removing depressed center
wheel
CAUTION:
Always be sure that the tool is switched off and
unplugged before installing or removing the wheel.
Mount the inner flange onto the spindle. Fit the wheel
on over the inner flange and screw the lock nut onto
the spindle. (Fig. 4)
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. 5)
WARNING:
Only actuate the shaft lock when the spindle is not
moving.
Switch action (Fig. 6)
CAUTION:
Before plugging in the tool, always check to see that
the switch actuates properly and returns to the ''OFF''
position when the rear of the switch lever is
depressed.
To switch on, depress the rear of the switch lever and
push it forward. Then depress the front of the switch
lever to lock it.
To switch off, depress the rear of the switch lever.
Operation (Fig. 7)
Hold the tool firmly with both hands. 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° – 30° to the workpiece surface.
During the break-in period with a new wheel, do not
work the griader 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 directions.
WARNING:
• It should never be necessary to force the tool. The
weight of the tool applies adequate pressure. Forc-
ing 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 for
Model 9526NB or 90 mm for Models 9527NB and
9528NB in diameter. Use of the wheel after this
point is unsafe and it should be removed from
service and rendered unusable by intentional
destruction.
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Replacing carbon brushes (Fig. 8 & 9)
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.
To maintain product safety and reliability, repairs,
maintenance or adjustment should be carried out by a
Makita Authorized Service Center.
