OPERATING THE SANDER
See Figures 7 - 8, page 9.
 Secure the workpiece to prevent it from moving under
the sander.
WARNING:
Unsecured workpieces could be thrown towards the
operator, causing injury.
WARNING:
Keep your head away from the sander and the sanding
area. Your hair could be drawn into the sander causing
serious injury.
 Place the sander on the workpiece so that all of the sand-
ing sheet surface is in contact with the workpiece.
NOTICE:
To avoid damaging the motor from overheating, be careful
not to let your hand cover the air vents.
CAUTION:
To ensure proper brake operation after extended use,
periodically check its operation by removing the sanding
disc, running your sander without load (off the workpiece)
and then turning off the sander. The backing pad should
not take longer than 6 seconds to stop. If it takes longer
than 6 seconds to stop, return the sander to your nearest
Authorized Service Center for repair. Failure to do so may
result in minor injury.
OPERATION
 Turn on the sander and move it slowly over the workpiece.
NOTE: The speed of orbit observed during use is de-
signed to give optimum results, and is not an indicator
of the tool's actual sanding performance.
 Make successive passes in parallel lines, circles, or
crosswise movements.
 Turn off the sander and wait until it comes to a complete
stop before removing it from the workpiece.
Do not force. The weight of the unit supplies adequate pres-
sure, so let the sanding disc and sander do the work. Apply-
ing additional pressure slows the motor, rapidly wears the
sanding disc, and greatly reduces sander speed. Excessive
pressure will overload the motor, causing possible damage
from motor overheating, and can result in inferior work. 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 action may remove too much material, making the
surface uneven.
Extended periods of sanding may tend to overheat the mo-
tor. If this occurs, turn sander off and wait until sanding disc
comes to a complete stop, then remove it from workpiece.
Remove the hand from vent area, remove sanding disc, then
with the hand removed from vent area, turn sander on and
run it free without a load to cool motor.
