DUST REMOVAL
When an excessive amount of dust is depos-
ited in the dust bag, dust-collecting efficien-
cy will sharply drop. Remove dust from the
bag when it is deposited up to about 2/3 the
bag capacity, where by dust collecting effi-
ciency (as well as working efficiency) will be
ensured.
STARTING THE MACHINE
1) The machine has an OF / OFF feature as
well as a button for CONTINUOUS OPERA-
TION.
2) To start up press and hold the ON/OFF
switch, to stop release the button.
3. For a continuous operation press the lock-
on button while pressing the on/off switch.
NOTE: Do not leave the machine with the
continuous operation feature activated. This
can cause accidental starting.
DURING OPERATION
WARNINGS
• Be careful not to let your hand completely
cover air vents.

2. Hold the sander in front and away from
you, keeping it clear of the workpiece. Start
the sander and let the motor reach its maxi-
mum speed. Gradually lower the sander on the
workpiece with a slight forward movement.
Move it slowly using forward and backward
strokes.
DO NOT FORCE IT! The weight of the unit sup-
plies adequate pressure, so let the belt sander
do the work. Applying additional pressure only
slows the motor, rapidly wears sandpaper and
greatly reduces sander speed.
NOTE: Any finish or resin on wood may soften
from the frictional heat. Do not allow sanding
on one spot too long as the sander's rapid ac-
tion may remove too much material, making
the surface uneven.
WARNING: Do not touch workpiece right
after sanding operation it will be hot and may
cause burning.
SANDING MOVEMENT
Hold the unit by the front and back handle.
Move the machine forward and then back-
ward, repeating this movement.
SELECT ABRASIVE BELT APPROPRIATE TO
EACH WORK:
Finished thickness, 30-40
Medium finish; 40-100
Semi-fine finish, 80-240
Fine finish, 180-40
NOTE: Use the same thickness of sandpaper
until you get a uniform finished surface.
Changing during the sanding process can
lead to a poor finish.
