Installing side grip (auxiliary handle) (Fig. 2)
Always install the side grip on the tool securely before
operation. The side grip can be installed in any of
three positions on the sides of the tool, whichever is
convenient and keeps the guard properly positioned.
Always hold the tool's switch handle and the side grip
firmly with both hands during operation.
Installing or removing depressed center
wheel (Fig. 3 & 4)
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.
NOTE:
Super flange
Models 9047F, 9057F, 9049F, 9059F, 9047SF,
9057SF, 9049SF and 9059SF are standard-equipped
with a super flange.
Only 1/3 of efforts needed to undo lock nut, compared
with conventional type.
Switch action (Fig. 5)
CAUTION:
Before plugging the tool, always check to see that the
switch trigger actuates properly and returns to the
''OFF'' position when released.
For U.K., Australia, France and Algeria
To prevent the trigger from being accidentally actu-
ated, a lock lever is provided. To start the tool, push
the lock lever in and then pull the trigger. Release the
trigger to stop.
For Germany, Austria, Italy, Netherlands, Belgium,
Spain, Portugal, Denmark, Sweden, Norway,
Finland and Greece
To prevent the trigger from being accidentally actu-
ated, a lock lever is provided. To start the tool, push
the lock lever in and then pull the trigger. Release the
trigger to stop. For continuous operation, push the
lock lever in, pull the trigger and then push the lock
lever further in. To stop the tool from the locked
position, pull the trigger fully, then release it.
For other countries than the above countries
To start the tool, simply pull the trigger. Release the
trigger to stop. For continuous operation, pull the
trigger and then push the lock lever. To stop the tool
from the locked position, pull the trigger fully, then
release it.
NOTE:
Models 9047S, 9057S, 9049S, 9059S, 9047SF,
9057SF, 9049SF and 9059SF begin to run slowly
when they are turned on. This soft start feature
assures smoother operation and less operator
fatigue.
Operation (Fig. 6)
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 tool 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 115 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.

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. 7)
Whenever carbon brushes must be replaced, they cut
out the tool automatically. When this occurs, replace
the carbon brushes at the same time. Use only
identical carbon brushes.
To maintain product safety and reliability, repairs,
maintenance or adjustment should be carried out by
Makita Authorized Service Center.
