OPERATION

clogged with polishing film, wash in lukewarm water with

a mild detergent. Allow bonnets to dry thoroughly before

reuse. Polish with a long sweeping motion, back and forth,

advancing along the surface to be polished. Do not hold the

tool in one spot or use a circular or spiral pattern. This will

cause swirls in the finish.

Spread a light coat of polish or wax over a small area.

Polish with the tool according to the manufacturer’s

instructions printed on the label of the polish or wax

container.

NOTE: Some polishes should be buffed while damp while

others must be allowed to dry; therefore, always check the

manufacturer’s label.

Tilt the tool so that the polishing bonnet is at a slight angle

to the work surface. Always start polishing at the top or

highest point and work down. This will prevent light dust

or polish film from being thrown upon completed section.

It also eliminates pulling the tool’s power cord over

sections already polished.

Surfaces that have an old film of wax or polish, or that

have not been polished or waxed for an extended

period of time, may require a second application. This is

especially true on oxidized surfaces. Heavily oxidized

surfaces should be cleaned with a commercial paste or liquid

cleaner before polishing or waxing.

WARNING:

Check polishing bonnets before each use. Make sure

they are clean and free from any loose particles or foreign

objects that may be embedded in the bonnet. Failure to

do so could cause these particles or objects to be thrown

from the tool resulting in possible serious injury.

INSTALLING OPTIONAL SANDING DISC

See Figure 5, page 11.

NOTE: A sanding disc is not supplied.

Unplug the sander/polisher.

Position the tool as shown and align the spindle lock hole

with the two half-circle notches in motor housing. Lock

spindle by inserting the pin provided through spindle lock

hole and trapping it in half circle notches. This will prevent

spindle from rotating.

Loosen spanner nut with the spanner wrench provided

by turning counterclockwise.

Remove spanner nut.

Center the sanding disc over the rubber disc and start

spanner nut onto threaded spindle in a clockwise

direction.

Securely tighten spanner nut with the spanner wrench

provided.

Remove pin securing spindle.

To remove:

Unplug the sander/polisher.

Position the tool as shown and insert pin to secure

spindle.

Loosen spanner nut with the spanner wrench provided

by turning counterclockwise.

Remove spanner nut.

Remove the sanding disc.

Reinstall spanner nut and tighten securely.

Remove pin securing spindle.

SANDING

See Figure 6, page 12.

Clamp or otherwise secure the work to prevent it from

moving under the sander/polisher. Secure small workpieces

in a vise or use clamps to secure them to a workbench.

WARNING:

Unsecured work could be thrown towards the operator

causing injury.

Hold the tool in front and away from you, keeping it clear

of the workpiece. Start the tool by depressing the switch

trigger and letting the motor build to its maximum speed.

Gradually lower sander/polisher to the workpiece at a slight

(5° to 8°) angle.

WARNING:

To prevent loss of control and possible serious personal

injury, always operate the tool with both hands, keeping

one hand on the side handle.

Do not attempt to hold the sanding disc flat on the

workpiece. Always keep the tool in motion moving over

the work, allowing it to operate freely without unneces-

sary pressure. The weight of the unit supplies adequate

pressure, so let the sanding disc and sander do the work.

Applying additional pressure only slows the motor, rapidly

wears sanding discs, and greatly reduces sander speed.

Excessive pressure will overload the motor, causing

possible damage from motor overheating, which can result

in inferior work. Any finish or resin on wood may soften from

the frictional heat.

Do not sand too long in one spot. This will cause uneven

sanding and gouging of the work.

Upon completion of a sanding operation, lift tool away from

work surface before turning off.

WARNING:

Sanding disc must come to a complete stop before set-

ting tool down on workbench. Failure to do so can cause

the tool to be thrown from workbench because of sanding

disc rotation. This could result in damage to the tool or

possible serious injury to the operator.
