ASSEMBLY & OPERATION
SANDING
– cont’d
Place sander on the workpiece so that the
complete sandpaper surface is in contact
with the workpiece. Turn the sander ON by
pressing on the side of the ON/OFF switch.
Move the sander slowly over workpiece
making successive passes in parallel lines,
circles or crosswise movements. Because
the orbital motion of the sanding pad moves
in tiny circles, it is not necessary to move
the sander with the grain or in the same
direction for successive passes (see
Fig. 7).
Upon completion of the sanding operation,
turn sander OFF by pressing on the other
side of the ON/OFF switch. Wait until the
sanding pad comes to a complete stop
before removing from the workpiece.
WARNING: Your sander should only
be turned ON when the entire surface of
the sanding pad is in contact with the
workpiece. Failure to follow this
sanding procedure could result in loose
sandpaper which could result in
possible injury.
NOTE: Hold the sander using the pad
grip on top of the sander. Be careful
NOT to cover the cooling vents with
your hand. Covering the cooling vents
could cause the motor to be damaged
by overheating.
DO NOT FORCE THE SANDER.
The
weight of the sander usually provides
adequate pressure. Let the sander and
sandpaper do the work. Applying added
pressure will slow the motor, increase the
wear on the sandpaper and greatly reduce
sander speed. Excessive pressure will
overload the motor causing possible
damage from the motor overheating. It will
also create an inferior finish on sanded
work. Any finish or resin on wood will soften
from the frictional heat, causing sandpaper
to become clogged quickly. Do not sand in
one spot too long as the sander’s rapid
action may remove too much material,
making the surface uneven.
Extended periods of sanding may tend to
overheat the motor. If this occurs, turn
sander OFF, wait until the sanding pad
comes to a complete stop and remove it
from the workpiece. Check to make sure
your hand has not been covering the
cooling vents. Let the motor cool before
continuing sanding operation.
