UNPACKING

Your sander has been shipped completely assembled and
ready for use. After removing it from the box, inspect it
carefully to make sure no breakage or damaged has occurred
during shipping. If any parts are damaged or missing, contact
your nearest Sears store to obtain replacement parts before
attempting to operate sander. A sanding disc pack and
owner's operating manual are included in the box.

KNOW YOUR SANDER

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

See

Figure 1.

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 personal injury.

OPERATION

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.

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 voltage drop of more than 10
percent 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.

SWITCH

See Figure 1.

To turn your sander 

ON

, depress the switch trigger. Release

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.
