OPERATION
Do not force. The weight of the unit supplies adequate
pressure to do the work. Applying additional pressure only
slows the motor, rapidly wears the sanding sheet, and greatly
reduces sander speed. Excessive pressure will overload the
motor causing possible damage from overheating and can
result in inferior work. Any finish or resin on wood may soften
from the frictional heat. Do not sand 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 overheat the motor. If this
occurs, turn the sander off and wait until the sanding sheet
comes to a complete stop. Remove sander from workpiece.
Remove your hand from vent area. Turn sander on and run
it free without a load to cool the motor.
For detail sanding such as corners and crevices, use the
tip of the sanding sheet with small, back and forth motions.
EMPTYING THE DUST BAG
See Figure 6, page 10.
For more efficient operation, empty the dust bag when it is
no more than half full to permit better air flow through the
bag. Always empty and clean the dust bag thoroughly upon
completion of a sanding operation and before storing.
WARNING:
Collected dust from sanding surface coatings such as
polyurethanes, linseed oil, etc. can self-ignite in the
sander dust bag or elsewhere and cause fire. To reduce
the risk of fire, empty the dust bag every 10-15 minutes
while sanding. Never store or leave a sander without
totally emptying its dust bag. Also follow the recommen-
dations of the coatings manufacturers.
 Unplug the sander.
 Remove the dust bag from the sander.
 Shake out the dust.
 Reattach the dust bag to the sander.
For a more thorough cleaning of the dust bag, remove dust
bag from dust bag frame and shake out dust. Replace dust
bag over frame then install dust bag assembly on sander.
CHANGING THE SANDING SHEETS AND
PADS
See Figure 7, page 11.
The sander is packed with sanding sheets and pads designed
for a variety of uses. To change, simply pull the used sheet
or pad off the base and attach the desired sheet or pad by
pressing it onto the base of the sander.
ATTACHING THE DUST BAG
See Figure 2, page 10.
The dust bag provides a dust collection system for the sander.
Sanding dust is drawn up through the holes of the sanding
sheet and collected in the dust bag during sanding.

Unplug the sander.
 Using a slight twisting motion, firmly slide dust bag as-
sembly over blower exhaust on sander.
TURNING THE SANDER ON/OFF
See Figure 3, page 10.
While holding the tool in normal operating position:
 Push the ON/OFF switch to the left to turn sander on.
 Push the ON/OFF switch to the right to turn sander off.
OPERATING THE SANDER
See Figures 4 - 5, page 10.
CAUTION:
Keep the cord away from the sanding pad and position
the cord so that it will not be caught on lumber, tools, or
other objects during sanding.
 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 sanding area.
Hair could be drawn into sander causing serious injury.
 Hold the sander in front and away from you, keeping it
clear of the workpiece.
NOTICE:
To avoid motor damage resulting from overheating, do
not cover the air vents with your hand.
 Start the sander and let the motor build to its maximum
speed.
 Gradually lower sander onto the workpiece so that all of
the sanding disc surface is in contact with workpiece.
 Move the sander slowly across the workpiece using small,
circular motions.
