KNOW YOUR SANDER

See Figure 1.

Before attempting to use your sander, familiarize yourself
with all operating features and safety requirements.

WARNING:

If any parts are missing do not operate your sander until
the missing parts are replaced. Failure to do so could
result in possible serious injury.

SWITCH

This tool is equipped with a simple switch control. To turn
your sander ON, depress the switch button as shown in
Figure 1. Depress the switch button in the opposite direction
to turn your sander OFF.

Your sander has a comfortable palm grip that provides easy
handling and positive control and is suitable for sanding with
coarse, medium, and fine grit sanding disc.

CONVERSION PAD

Converts the standard sanding pad from use with pressure
sensitive sanding discs for use with velcro type sanding discs.

FEATURES

RANDOM ORBIT

The random orbit motion provides overlapping sanding
movements by combining orbital and turning motion. These
overlapping sanding movements provide fast cutting action
with excellent sanding results.

ELECTRICAL CONNECTION

Your sander has a precision built electric motor. It should be
connected to a power supply that is 120 volts, 60 Hz, AC
only (normal household current). 
Do not operate this tool
on direct current (DC). A substantial voltage drop will cause
a loss of power and the motor will overheat. If your tool does
not operate when plugged into an outlet, double-check the
power supply.

WARNING:

Do not allow familiarity with your sander to make you
careless. Remember that a careless fraction of a second
is sufficient to inflict severe injury.

APPLICATIONS

(Use only for the purposes listed below)

Sanding on wood surfaces.

The operation of any sander can result in foreign objects being thrown into your eyes,
which can result in severe eye damage. Before beginning power tool operation, always
wear safety goggles or safety glasses with side shields and a full face shield when
needed. We recommend Wide Vision Safety Mask for use over eyeglasses or standard
safety glasses with side shields.
