Values and risk of harm experienced by an individual

INTENDED USE
This tool is intended to be used with abrasive sanding
discs for the finish sanding of materials such as wood,
metal, fiberglass 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 efficiency 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 filter, 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, flush the
tool with a few drops of oil and run for 10 seconds. This
will help remove contaminants and reduce the
formation of rust.
OPERATION
Speed of the tool may be adjusted by turning the
regulator located near the air inlet.
Disconnect tool from air supply before installing or

INSTALLING SANDING DISC
HOOK and LOOP
Center sanding pad on backing pad and apply firm
