This tool is intended to be used with abrasive sanding discs for the fi nish sanding of materials such as
wood, metal, fi berglass and similar materials. If it is used for anything else, it is considered misuse, creates
a hazard and may void the warranty.
AIR SUPPLY
The effi ciency and life of this tool depend on the proper supply of clean, dry air at a maximum of 90 PSI. The
use of an airline fi lter, pressure regulator, and lubricator is recommended. Before connecting to tools, blow
out the airline to remove water and dirt that may have accumulated.
HOSE AND HOSE CONNECTIONS
The air supply hose recommended is 3/8" (10mm) I.D. If an extension hose is necessary, use 1/2" (13mm)
ID hose with couplings not less than 3/8" (10mm) I.D. The tool inlet thread is 1/4" NPT.
LUBRICATION
For maximum performance and tool life, an airline lubricator, set to deliver 1 drop per minute. Snap-on IM6
Air Motor Oil is recommended. If an airline lubricator is not used, add 8 to 10 drops of air motor oil to the air
inlet at the start of the day and run the tool for 10-20 seconds.
Do not over lubricate because excess oil may contaminate the surface being sanded.
MAINTENANCE
Water, dust and other airline contaminants can cause rust and vane sticking. After long idle periods, fl ush
the tool with a few drops of oil and run for 10 seconds. This will help remove contaminants and reduce the
formation of rust.
