Switch action (Fig. 6)
CAUTION:
• Before plugging in the tool, always check to see that
the switch trigger actuates properly and returns to the
“OFF” position when released.
• The tool should not be in contact with the workpiece
surface when you turn the tools on or off. Otherwise a
poor sanding finish or damage of the belt may result.
To start the tool, simply pull the trigger. Release the trig-
ger 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.
Sanding operation
Hold the tool firmly with both hands. Turn the tool on and
wait until it attains full speed. Then gently place the tool
on the workpiece surface. Keep the belt flush with the
workpiece at all times and move the tool back and forth.
Never force the tool. The weight of the tool applies ade-
quate pressure. Excessive pressure may cause stalling,
overheating of the motor, burning of the workpiece and
possible kickback.
Connecting to Makita vacuum cleaner or dust collector
Cleaner sanding operations can be performed by connecting the belt sander to Makita vacuum cleaner or dust collec-
tor.
When connecting to Makita vacuum cleaner (Model 406/431), an optional hose 28 mm in inner dia. or joint 25 is neces-
sary. See the figure below.
When connecting to Makita dust collector (Model 420), the optional hose or joint is not necessary. You can connect the
belt sander directly to the hose of the dust collector.
Carbon plate (Fig. 7)
For greater sanding efficiency and to help the belt run
cooler, install an optional carbon plate on the steel plate
when sanding hardwood or steel.
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. 8&9)
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, mainte-
nance or adjustment should be carried out by a Makita
Authorized Service Center.
