SANDER PAD ASSEMBLY CONTINUED

• To assemble the 

sanding

  

  pad  (B), place the supplied 

  wrench onto the 

balance  

  

shaft nut (H)

• Hold the wrench firmly and 

  insert the threaded post on  

  the 

sander pad (B) into the 

  

balance shaft nut (H).  

  Tighten by turning the  

  

sander pad (B) clockwise.

OPERATING PROCEDURES

START-UP (FIG. 1, PG. 2)

• Turn on the air compressor and allow the air tank to be filled.

• Set the air compressor regulator to 90 PSI. This air 

  tool operates at a maximum of 90 PSI air pressure.

• Depress the trigger to start operating the tool.

 SHUT-DOWN (FIG. 1, PG. 2)

 • Release the trigger to stop the tool.

• Always disconnect air supply when changing sandpaper pads.

• When job is completed, turn off the air compressor and store

  the air tool after lubrication.

Tips

• Begin sanding with an abrasive grit sandpaper coarse 

  enough to remove the high spots. Progress to a finer grit 

  sandpaper until the desired finish is obtained.

• Never change from coarse grit sandpaper to a very fine grit 

  sandpaper, always progress gradually to the finer grit.

OPERATING INSTRUCTIONS

• Select a suitable abrasive disc and make sure that it is fixed

  securely to the tool. 

• Connect to suitable air supply as recommended.

• Apply the sander lightly to the work and allow the abrasive 

  disc to cut. Take great care when sanding around sharp 

  edges and surfaces to avoid the disc snagging i.e. the disc 

  may be brought to an abrupt stop or considerably slowed, 

  causing the tool to kick in the hands.

NOTE: Use of safety glasses and a breathing mask is 

recommended. Sanding certain materials may create 

hazardous dust which may require special breathing 

equipment. Check before using the tool. Although the tool has 

a low noise level, the actual sanding process may cause a 

noise level such that ear protectors will be required. Safety 

gloves are recommended.

Do not continue to use abrasive discs that are worn or clogged.

Do not use undersized or oversized sanding discs. The disc 

should be no more than 1/4” larger in diameter than the pad, 

and not smaller than the pad.

MAINTENANCE

Lubrication

Air tools require lubrication throughout the lifetime of the tools. 

The air motor and bearing uses compressed air to power the tool. 

The compressed air contains moisture that will rust the air motor 

and other parts in side of the tools, therefore lubrication is required 

daily.  Failure to lubricate the air tool properly will dramatically 

shorten the life of the tool and will void the warranty

CAUTION: This air tool requires lubrication BEFORE initial use, 

also before and after each additional use.
