necessary. If in doubt, wear the protective equip-
ment.
2. Always be sure that the tool is switched off and
unplugged before carrying out any work on the
tool.
3. Keep guards in place.
4. Use only wheels with correct size and wheels
having a maximum operating speed at least as
high as the highest No Load Speed marked on

cially the installing surface) or the lock nut. Dam-
age to these parts could result in wheel
breakage.
10. For tools intended to be fitted with threaded hole
wheel, ensure that the thread in the wheel is long
enough to accept the spindle length.
11. Before using the tool on an actual workpiece,
test run the tool at the highest no load speed for
at least 30 seconds in a safe position. Stop

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 9526PB) or
counterclockwise (for 9527PB and 9528PB). Be sure to
tighten the screws securely.
Installing side grip (auxiliary handle) (Fig. 3)
For your own safety always use the side grip. The side
grip can be installed on either side of the tool.
Installing or removing the 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.
Installing or removing diamond wheel
(accessory) (Fig. 6 & 7)
CAUTION:
• Make sure that the arrow on the tool should point in the
same direction as the arrow on the diamond wheel.
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.
Switch action (Fig. 8)
CAUTION:
• Do not pull the switch trigger forcibly without pushing in
the lock-off button.
• Before plugging in the tool, always check to see that
the switch actuates properly and returns to the “OFF”
position when released.
To prevent the switch trigger from being accidentally
actuated, a lock-off button is provided. To start the tool,
push in the lock-off button and then pull the switch trig-
ger. Release the switch trigger to stop. For continuous
operation, pull the switch trigger and then push in the
lock-on button. To stop the tool from the locked position,

Operation (Fig. 9)
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. 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 cen-
ter wheel should not be used after it has been worn
down to 75 mm in diameter for Model 9526PB or 90 mm
for Models 9527PB and 9528PB in diameter. Use of the
wheel after this point is unsafe and it should be
removed from service and rendered unusable by inten-
tional destruction.
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 are dust or dirt around the tool, the tool
may suck in them.
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 for-
ward 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.
Replacing carbon brushes (Fig. 10 & 11)
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,
any other maintenance or adjustment should be per-
formed by Makita Authorized or Factory Service Centers,
