OPERATING INSTRUCTIONS
Installing side grip (auxiliary handle) (Fig. 1)
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 (Fig. 2 & 3)
Important:
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.
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.
To remove the wheel, follow the installation procedure
in reverse.
Switch action (Fig. 4)
CAUTION:
Before plugging the tool, always check to see the
switch trigger actuates properly and returns to the
''OFF'' position when released.
To start the tool, simply pull the trigger. Release the
trigger to stop. For continuous operation, pull the
trigger and then push in the lock button. To stop the
tool from the locked position, pull the trigger fully, then
release it.

Operation (Fig. 5)
Hold the tool firmly. 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 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 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 90 mm for 9005B and
9005BS or 100 mm for 9006B 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.
Replacement of carbon brushes (Fig. 6 & 7)
Replace carbon brushes when they are worn down to
the limit mark. Both identical carbon brushes should
be replaced at the same time.
To maintain product safety and reliability, repairs,
maintenance or adjustment should be carried out by a
Makita Authorized Service Center.
