WARNING:

Never become complacent while using your sander, as
carelessness can result in serious personal injury.

INSTALLING SANDPAPER

Inspect sandpaper before installing. DO NOT use broken
or defective sandpaper.

1. Unplug your sander.

WARNING:

Failure to unplug your sander could result in accidental
starting causing possible serious personal injury.

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.

PREPARING FOR OPERATION

CAUTION:

Be careful not to let your hand completely cover air vents.

SANDING

(Fig. 1)

WARNING:

Unsecured work could be thrown towards the operator
causing injury.

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.

OPERATION

WARNING:

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.

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.

WARNING:

Do not wear loose clothing or jewelry when operating
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.

ORBITAL MOTION

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.

(Fig. 2)

TO ATTACH THE DUST BAG ASSEMBLY (Fig. 3)

Follow these directions to attach the dust bag assembly.

Unplug the sander.

Fig. 3

WARNING:

Failure to unplug the tool could result in accidental starting
causing possible serious injury.

Insert the dust bag into the dust extraction port as
illustrated.

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

Unplug your sander.

WARNING:

Failure to unplug your sander could result in accidental
starting causing possible serious personal injury.

Fig. 2

WARNING:

Collected sanding dust from sanding surface coatings
such as polyurethanes, linseed oil etc. can self-ignite in
your sander dust bag or elsewhere and cause fire. To
reduce the risk of fire always empty your dust bag frequently
while sanding and never store or leave a sander without
totally emptying its dust bag. Also follow the
recommendations of the coatings manufacturers.

USING THE DUST BAG ASSEMBLY

The dust bag assembly provides a dust collection system
for the sander. Sanding dust is drawn up through the
holes of the sanding disc and collected in the dust bag
during sanding.

Remove the dust bag assembly from the sander.
Disassemble the dust bag from the dust bag assembly.
Shake out the dust.
Insert the dust bag to the dust frame.

Replace the dust bag assembly on the sander.
