OPERATING INSTRUCTIONS

NOTE:

 For additional information regarding the parts listed in the following pages, refer

to the 

Assembly Diagram

 

on

 

page 12

.

1.

CAUTION:

 Always make sure the Power Cord (17) of the Sander is unplugged from

its electrical outlet 

prior to making any adjustments to the tool.

2.

Clamp your workpiece down, or insert it in a vise.  Make sure the wood you are
sanding does not have any nails or metal of any kind in it, or you will ruin the
sandpaper and damage the Pad (28).

3.

After donning the appropriate safety gear covered on page 2 of this manual, plug in
the Sander.

4.

Turn on the Sander by turning on the Switch (3).

5.

Always run the Sander for a few seconds before contacting the workpiece.

6.

Contact the workpiece with minimal pressure.  If the Sander is not removing enough
material, try a grittier piece of sandpaper.  If you want to remove a lot of material fast,
use a belt sander.

Note:

All orbital sanders leave sanding marks on the workpiece.  To minimize sanding
marks, always try to sand with the grain of the wood.

7.

Occasionally check the sandpaper for tears, wear, or fraying.  Replace if necessary.

8.

When you are finished, turn off the Switch (3).
