Maintenance - Makita 9047 Manual

For Australia and New Zealand
Screw the lock nut with its protrusion facing downward
(facing toward the wheel).
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.
Installing or removing cut-off wheel (Fig. 5 & 6)
For Australia and New Zealand
Mount the inner flange onto the spindle. Fit the cut-off
wheel on over the inner flange.
Mount the outer flange on the wheel and screw the lock
nut with its protrusion facing downward (facing toward the
wheel).
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. 7)
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 actuated, 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 actuated, 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 trig-
ger 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 oper-
ation and less operator fatigue.
Operation (Fig. 8)
CAUTION:
After operation, always switch off the tool and wait until
the wheel has come to a complete stop before putting the
tool down.
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. 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 115 mm (4-1/2") in diameter. Use of the wheel
after this point is unsafe and it should be removed from
service and rendered unusable by intentional destruc-
tion.

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. 9 & 10)
When the resin insulating tip inside the carbon brush is
exposed to contact the commutator, it will automatically
shut off the motor. When this occurs, both carbon
brushes should be replaced at the same time. Use only
identical carbon brushes.
To maintain product safety and reliability, repairs, mainte-
nance or adjustment should be carried out by a Makita
Authorized Service Center.
