ORBITAL MOTION
See Figure 5, page 12.
Orbital motion is ideal for fast cutting action when removing
old finishes, smoothing rough wood, cutting stock down to
required dimensions, or for finishing surfaces to be painted.
As shown in figure 5, the sandpaper moves in tiny circles
at a very high speed, allowing the sander to move easily.
REMOVING PRESSURE SENSITIVE ADHESIVE
(PSA) SANDPAPER BEFORE STORAGE
Do not store the sander with the sandpaper installed. Heat
generated from sanding causes the pressure sensitive
adhesive to flow and form a tight bond between the backing
pad and sandpaper.
Removing the sandpaper soon after you have finished a
sanding operation avoids letting the adhesive set up. If the
sandpaper is left on the backing pad for an extended period
of time after use, the adhesive will set up and cause the
sandpaper to become difficult to remove.
It may also tear when removing. When this situation occurs,
it becomes difficult to clean the backing pad for the next
sheet of sandpaper.
NOTE: If you forget to remove the sandpaper after a sand-
ing operation, sand for a few minutes to soften the adhesive
backing before attempting to remove sandpaper.
USING THE DUST BAG
The dust bag provides a dust collection system for the
sander. Dust is drawn up through holes in the sandpaper
and cushion and collected in the dust bag during sanding.
ATTACHING THE DUST BAG ASSEMBLY
See Figure 6, page 12.
 Unplug the sander.
 Slide the dust bag assembly onto the blower exhaust on
the sander using a slight twisting motion.
CLEANING THE DUST BAG
See Figures 6 - 7, page 12.
For more efficient operation, empty the dust bag when it is
no more than half full. This will permit the air to flow through
the bag better.
OPERATION
To empty the dust bag:
 Unplug the sander.
 Remove the dust bag assembly from the sander and
shake out dust.
 For a more thorough cleaning of the dust bag, remove
dust bag from the frame and shake out dust.
 Replace the dust bag over the frame, then reinstall on the
sander.
WARNING:
Collected sanding dust from sand ing 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, always empty the dust bag frequently
(10-15 minutes) while sanding and never store or leave a
sander without totally emptying its dust bag. Also follow
the recommendations of the coatings manufacturers.
ATTACHING SANDER TO VACUUM
See Figure 8, page 12.
When sanding for an extended period of time, you can easily
attach the dust collection system of the sander to a vacuum.
To attach:
 Unplug the sander.
 Remove dust bag from sander.
 Attach vacuum hose to dust exhaust.
NOTE: Vacuum hose fits inside dust exhaust.
 Connect sander and vacuum to power supply.
WARNING:
When sander is not connected to vacuum, always install
dust bag back on sander. Failure to do so could cause
sanding dust or foreign objects to be thrown into the
face or eyes which could result in possible serious injury.
