OPERATION
Your sander should never be connected to power supply
when you are assembling parts, making adjustments,
assembling or replacing sandpaper, cleaning or when
not in use. Disconnecting sander will prevent accidental
starting that could cause serious personal injury.
FEATURES
Your sander is suitable for sanding with coarse, medium, and
fine grit sandpaper. It will produce a fine scratch free finish
when used to sand with the grain on wood surfaces.
Before attemptingtouseyoursander,familiarizeyourself
with all operating features and safety requirements.
SWITCH
To turn the tool on, squeeze the trigger switch. To turn the
tool off, release the trigger switch. The trigger is spring
loaded and will return to the off position automatically.
LOCK ON BUTTON
The sander is equipped with a lock on button which is
designed for continuous sanding for extended periods. This
button locks the trigger switch on so you can focus on your
work. To activate the lock on feature:
a. Squeeze the trigger switch first.
b. Depress the lock on button then.
c. Finally rel
ease the trigger switch.
To release the lock or to turn off the sander, simply squeeze
and release the trigger switch.
VARIABLE SPEED DIAL
A variable speed dial is incorporated into the trigger switch.
You can select different speed by adjusting this dial. To
have the lowest speed application, turn the dial to
A . To
have full speed application, turn the dial to F.
For ease of operation, your sander has both loop handle
and rear handle for two handed operation, which is
necessary to maintain proper control. During operation,
always use both hands.
Hold your sander in front and away from you, keeping it
clear of the work piece. Start your sander by squeezing
the trigger switch and letting the motor build to its maximum
speed. Gradually lower your sander on the work with a
slight forward movement. Move it slowly using forward and
backward strokes.
Holes in sandpaper must line up with holes in backing
pad in order for the dust collection feature of your sander
to function properly.
Note: DO NOT use sander without sandpaper. Doing so
will damage the cushion.

APPLICATIONS
You may use the random orbital sander for the purposes
listed below:
Sanding on wood surfaces.
Removing rust from and sanding steel surfaces.
Sanding plastics.
INSTALLING SANDPAPER
Inspect sandpaper before installing. DO NOT use broken
or defective sandpaper.

SANDING
(Fig. 1)
Unsecured work could be thrown towards the operator
causing injury.
WARNING:
Fig. 1

Unplug your sander.
Remove the dust bag assembly from the sander.
Insert the dust bag to the dust frame.
Replace the dust bag assembly on the sander.
OPERATION
DO NOT FORCE. The weight of the unit supplies adequate
pressure, so let the sandpaper and sander do the work.
Applying additional pressure only slows the motor, rapidly
wears sandpaper 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.
ORBITAL MOTION (Fig. 2)
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. The sandpaper moves in tiny circles at a very high
speed, allowing the sander to move easily.

TO EMPTY THE DUST BAG ASSEMBLY (Fig. 4 & 5)
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. Always empty and clean the
dust bag thoroughly upon completion of a sanding
operation and before placing the sander in storage.
TO EMPTY THE DUST BAG
USING THE DUST BAG ASSEMBLY
Thedust bag assemblyprovides a dustcollection system
for the sander. Sanding dust is drawn up through the
holes of the sanding disc and collected in the dust bag
during sanding.

sander. They could get caught in moving parts causing
serious injury. Keep head away from sander and sanding
area. Hair could be drawn into sander causing serious
injury.

such as polyurethanes, linseed oil etc. can self-ignite in
your sander dust bag or elsewhere and cause fire. To
