Attaching or Removing the Pad

1. Disconnect the tool from its powersource before attaching or removingthe Pad (45C).

2. Rest the tool on a flat surface.Thread the Pad into the DriveSpindle (38C) until it is tight.

3. Place a 6” diameter pad of adhesive backed sandpaper (not included) ontothe pad. Press it firmly into place.

4. To remove the sandpaper, peel it from the Pad (45C). You may need to use ascraping tool to completely remove it.

5. To remove the Pad from the tool, rotate the Orbital Hub (41C) vertical onthe groove of the Drive Spindle (38C) to hold it in place. Rotate the Pad(45C) counterclockwise to remove it from the tool.

To Adjust the Sander for Circular or Orbital Motion

1. The sander may be adjusted for circular or orbital motion. In circular motion,the sanding pad spins around its center. In orbital motion, in addition tospinning around its center, the entire pad rotates around the axis of the toolspindle.

2. To adjust the sander forcircular motion, position theround edge of the OrbitalHub (41C) against the roundedge of the Drive Spindle(38C). To adjust the Sanderto move in an orbital motion,position the flat edge of theOrbital Hub (41C) againstthe round edge of the DriveSpindle (38C). Please seethe photo.

Using the Sander

1. Be sure all safety precautions are being followed.

2. Tighten workpieces to your workbench or other fixed base so that both of yourhands are free to hold the Sander.

3. Set the air compressor regulator to 90 psi. Connect the Air Sander to the aircompressor hose at the Air Inlet (2C). Use the Air Regulator (19C) to adjustthe air pressure as required.

4. Check to be sure all attachments are secure before turning on the tool.

5. Grip the handle with one hand, and the Housing (1C) with the other. Depress theTrigger (16C) to turn the tool on. Allow the motor to reach its full speed beforesanding. Be sure the tool is operating properly, and running smoothly beforeproceeding.

6. Apply the sanding pad to the work material at a slight angle. Move the sandingpad around the surface of the work material as needed. Do not allow the padto remain in one place as this may burn the work material. If the sander slowsdown appreciably, you are applying too much pressure. Always keep yourbody and clothing away from the moving sanding pad.

7. When you are done sanding, remove the tool from the work material, and releasepressure from the Trigger (16C). Allow the tool to come to a complete stopbefore setting it down. Disconnect the air pressure hose when the tool is not inuse.

Some Tips About Sand Paper

1. When sanding, start with a relatively coarse grit paper, and work up to a finergrit to complete the job. The grit selected depends on the job at hand. Withbare metal finishing, you may start at 100 and work up to 600 grit. With paintfinishing, you may start with 400 and work up to 2000 grit, for example. Yourchoice of grit depends on the job and your preferred method of working.NOTE: Harbor Freight Tools cannot be responsible for damage toproperty due to incorrect selection of sanding disc or grit size. Alwayspractice on scrap material before using the tool on your workpiece.

2. Sand paper works by moving a large number of sand grains in an arbitrarypattern over the work surface. Because of the Backing Pad, these will producea relatively uniform series of hills and valleys at the grain size of the grit used.Using the first grit selected, sand out any scratches or blemishes in the finish.You want to produce an even finish at the grain size of the grit being used.

CAUTION: Always wear ANSI approved safety goggles and full face shield, withdust mask or respirator while sanding.


NOTE: Your Sander features an Air Regulator (19D), allowing you to vary the amountof air pressure to the tool. Turn the regulator knob clockwise to increase the air flow,counterclockwise to restrict it.
