ATTACHING A VACUUM TO THE SANDER
See Figure 6, page 11.
When sanding for an extended period of time, you can attach
a vacuum hose to the sander.
To attach:
 Unplug the sander.
 Remove dust box from the sander.
 Attach a 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 collection box back onto the sander. Failure to do
so could cause sanding dust or foreign objects to be
thrown into the face or eyes which could result in pos-
sible serious injury.
ORBITAL MOTION
See Figure 7, page 11.
Orbital motion is ideal for removing old finishes, smoothing
rough wood, cutting stock down to required dimensions, or
for finishing surfaces to be painted. The sandpaper moves
in tiny circles at a high speed, allowing the sander to move
easily over the workpiece.
CALIFORNIA PROPOSITION 65
WARNING:
This product and some dust created by power sanding, sawing, grinding, drilling, and other construction activities may
contain chemicals, including lead, known to the State of California to cause cancer, birth defects, or other reproductive
harm. Wash hands after handling.
Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products and,
• arsenic and chromium from chemically treated lumber.
Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your
exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially
designed to filter out microscopic particles.
OPERATION
OPERATING THE SANDER
See Figure 8, page 11.
WARNING:
Clamp or otherwise secure work to prevent it from moving
under the sander. Failure to do so could result in unse-
cured work being thrown towards the operator, resulting
in possible serious injury.
Hold the sander in front of and away from you, keeping it
clear of the workpiece. Start the sander by sliding the switch
button to the on position and letting the motor build to its
maximum speed. Gradually lower the sander on the work
with a slight forward movement. Move it slowly using forward
and backward strokes.
Do not force. The weight of the unit supplies adequate
pressure, so let the sandpaper and sander do the work.
Applying additional pressure slows the motor, rapidly wears
sandpaper and greatly reduces sander speed. Excessive
pressure will overload the motor, possibly causing damage
that results in inferior work.
Any finish or resin on wood may soften from the frictional heat.
Do not sand one spot too long, as the sander's rapid action
may remove too much material, making the surface uneven.
Always remove the sander from the workpiece before turn-
ing it off.
CAUTION:
Be careful not to let your hand cover the air vents.
FLUSH SANDING
See Figure 9, page 11.
Every side except the rear of the sander allows flush sand-
ing in corners.
