Operation; Maintenance - Makita M9400 Instruction Manual

When the dust bag is about half full, remove the dust
bag from the tool and pull the fastener out. Empty the
dust bag of its contents, tapping it lightly so as to
remove particles adhering to the insides which might
hamper further collection.

OPERATION

Sanding operation
Fig.7
CAUTION:
The tool should not be in contact with the
•
workpiece surface when you turn the tool on or off.
Otherwise a poor sanding finish or damage of the
belt may result.
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
adequate pressure. Excessive pressure may cause
stalling, overheating of the motor, burning of the
workpiece and possible kickback.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and
•
unplugged before attempting to perform inspection
or maintenance.
Never use gasoline, benzine, thinner, alcohol or
•
the like. Discoloration, deformation or cracks may
result.
