1.

WARNING!

 

  Always make sure the Throttle Lever (11) is in its “OFF”

position, disconnect the Sander from its compressed air supply, and
squeeze the Throttle Lever to release any remaining air pressure from the
tool, before performing any inspection, adjustments, maintenance, or clean-
ing.

2.

Before each use,

 inspect the general condition of the Sander.  Check for loose

screws, misalignment or binding of moving parts, cracked or broken parts, dam-
aged air hoses, loose, cracked, or bent Pad (37), and any other condition that may
affect its safe operation.  If abnormal noise or vibration occurs, have the problem
corrected before further use.  

Do not use damaged equipment.

3.

Daily: 

With a soft brush, cloth, or vacuum, remove all dust and debris from the

Sander.  Then, use a premium quality, lightweight machine oil to lubricate all
moving parts 

except the Pad (37).

To Operate The Sander:

1.

IMPORTANT:  Before first use, it is recommended to test the Sander on
scrap material to determine the cutting capacity of the Sanding Paper.

2.

Connect the air supply hose to the Sander.  Turn on the air compressor (not in-
cluded), and set its regulator to the recommended 90 PSI for the Sander.

(See Figure A.)

3.

In order to keep the air supply hose out of the way, hang it over your shoulder.

4.

Grip the Sander firmly with 

both

 hands.  Then squeeze the Throttle Lever (11) and

allow the Pad (37) to move to its fullest speed.  

NOTE:

  The Sander features

variable speed action.  The harder the Throttle Lever is squeezed, the faster the
Sander operates.  

(See Figure B.)

5.

NOTE:

  If the Sander will not turn properly when it contacts the workpiece, discon-

nect the air supply and verify that the Orbital Hub (28) is in the unlocked position.

(See Figure C and instructions on page 7.)

6.

Sand the workpiece evenly with gentle, broad, sweeping strokes in a crisscross
pattern.

7.

During the sanding process, it may be necessary to occasionally stop the Sander,
disconnect it from its air supply hose, remove the worn Sanding Paper and re-
place with new Sanding Paper.

8.

Once the sanding is completed, release pressure on the Throttle Lever (11) to
stop the Sander.  Turn off the air compressor.  Disconnect the Sander from its air
supply hose.  Then squeeze the Throttle Lever once again to release any
remaining air pressure from the tool.  

(See Figure B.)
