OPERATION OPERATING THE SANDER See Figures 7 - 8.  Secure the work to prevent it from moving under the sander. WARNING: Unsecured work could be thrown towards the operator causing injury.  Place the sander on the workpiece so that all of the sanding disc surface is in contact with the workpiece. CAUTION: Be careful not to let your hand cover the air vents.  Start the sander and move it slowly over the workpiece.  Make successive passes in parallel lines, circles, or crosswise movements. NOTE: The front edge of the sander allows for flush sanding.  Turn the sander off and wait until the sanding disc comes to a complete stop before removing it from the workpiece. WARNING: Before connecting the sander to power supply source, always check to be sure the switch is not in the ON position. Failure to do so could result in accidental starting of the sander resulting in possible serious injury. Do not press down on the sander. The weight of the unit supplies adequate pressure, so let the sanding disc and sander do the work. Applying additional pressure only slows the motor, rapidly wears 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 motor. 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. 12 Fig. 7 Fig. 8

OPERATING THE SANDER
See Figures 7 - 8.
Secure the work to prevent it from moving under the
sander.
WARNING:
Unsecured work could be thrown towards the operator
causing injury.
Place the sander on the workpiece so that all of the sand-
ing disc surface is in contact with the workpiece.
CAUTION:
Be careful not to let your hand cover the air vents.
Start the sander and move it slowly over the workpiece.
Make successive passes in parallel lines, circles, or
crosswise movements.
NOTE:
The front edge of the sander allows for flush
sanding.
Turn the sander off and wait until the sanding disc
comes to a complete stop before removing it from the
workpiece.
WARNING:
Before connecting the sander to power supply source,
always check to be sure the switch is
not
in the
ON
position. Failure to do so could result in accidental starting
of the sander resulting in possible serious injury.
Do not press down on the sander. The weight of the unit
supplies adequate pressure, so let the sanding disc and
sander do the work. Applying additional pressure only slows
the motor, rapidly wears 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.
