instructions.

Operation 

 

The pneumatic sander must 

be properly lubricated before operation. See 
“Lubrication” section. 

 

Figure 1 

1. 

To install backing pad, turn spindle lock to 
engage spindle and keep it stationary. 
Thread backing pad onto spindle. Turn 
spindle lock to disengage spindle. 

2.  Mount a 6-in. PSA (Pressure Sensitive 

Adhesive) sanding disc (not provided) to the 
surface of sanding pad, making sure it is 
centered. 

3. 

Adjust speed using air regulator knob. 

4. 

Remove protective cap from air inlet (Figure 
1). If an in-line oiler is not being used, add 4 
or 5 drops of air tool oil (not included) into the 
air inlet. 

5.  Blow out air line to remove any dirt or 

moisture, then connect air supply hose to 
tool. Set air pressure to 90 psi. 

IMPORTANT:

 Connecting a quick-change 

coupling directly to the tool is not 
recommended, as vibration may cause the 
connection to fail. Instead, add a leader hose 
and install any quick-change couplings 
farther down the line. 

6.  Turn spindle lock to create either random 

orbit or simple rotary motion. 

7. 

Press and hold throttle lever to start sander. 
Allow tool to reach operating speed before 
placing on workpiece. Use both hands to 
operate. 

8. 

Release throttle lever to stop sander. 

Maintenance 

Lubrication 

The sander should be lubricated 

daily

 (or before 

each use) with air tool oil through the air inlet. 
During continual operation, it should be re-oiled 
every 1 to 2 hours. This can be done with an in-
line oiler, or manually. If done manually, proceed 
as follows: 

1. 

Disconnect air hose from tool. 

2. 

Place 4 or 5 drops of air tool oil into air inlet. 

NOTE: Air tool oil not provided; it is available 
at most major hardware and tool stores. SAE 
#10 oil or sewing machine oil may be used 
as a substitute. Do not use detergent oil. 

3. 

Re-connect air. Run sander at low throttle 
without load for a few seconds to distribute 
the oil throughout tool. 

4. 

When finished operating sander, disconnect 
air hose. Wipe off housing with a dry cloth. 
Place 4 or 5 drops of air tool oil into air inlet; 
re-connect air and run tool for a few seconds 
to distribute the oil. Disconnect air. 

Periodically apply 1 or 2 drops of air tool oil to 
throttle lever hinge area, and work lever to 
distribute the oil.
