WARNING" Before connecting the sander to power
supply source, always check to be sure the switch is
in the OFF position. Failure to do so could result in
accidental starting of the sander resulting in possible
serious injury.
CAUTION: Be careful not to let your hand cover the
air vents.
ON/OFF SLIDE SWITCH
This sander is equipped with a simple slide switch control.
To turn the sander ON, slide the switch in the direction
shown by the arrow in figure 1. To turn the sander OFF,
slide the switch in the opposite direction.
VARIABLE SPEED SWITCH
(MODEL 112180 ONLY}
The variable speed feature allows the sander to operate
at speeds that can be adjusted by rotating the dial on the
variable speed switch from A to R The dial is conveniently
located on the motor housing, allowing operator control of
disc speed. To increase sanding disc speed, turn the dial
on the variable speed switch to a higher setting. Turn dial
to a lower setting to decrease sanding disc speed.
SANDING
See Figures 6 - 7.
Clamp or otherwise secure the work to prevent it from
moving under the sander.
_IL WARNING: Unsecured work could be thrown
towards the operator causing injury.
Place sander on workpiece so that all of sanding disc
surface is in contact with workpiece. Start the sander and
move it slowly over workpiece making successive passes
in parallel lines, circles, or crosswise movements. Upon
completion of sanding operation, turn sander off and
wait until sanding disc comes to a complete stop before
removing from workpiece.

Do not force. 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 pos-
sible 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 sand-
ing disc comes to a complete stop, then remove it from
workpiece. Remove your hand from vent area, remove
sanding disc, then with your hand removed from vent
area, turn sander on and run it free without a load to cool
motor.
Flush sanding can be performed with the sander. The front
edge of the sander allows flush sanding. Upon completion
of sanding operation, turn sander off and wait until sand-
ing disc comes to a complete stop before removing from
workpiece.
_I_ CAUTION: To ensure proper brake operation after
extended use, periodically check its operation by
removing the sanding disc and running the sander
without load (off the workpiece). The backing pad
should not take longer than 6 seconds to stop. If
it takes longer than 6 seconds to stop, then brake
should be replaced.
NOTE: The brake is available and can be purchased
through Replacement Parts at your nearest Sears Service
Center.
