AIR SUPPLY
The efciency and life of this tool depend on the proper
supply of clean, dry, lubricated air at 90 lbs. P.S.I., although
lower pressures may be used. The use of an air line lter,
pressure regulator, and lubricator is recommended, (such
as Sioux 1660).
Before connecting the tool, blow the air line to remove
water and dirt, which may have accumulated. This is es-
pecially important for a new line or when the line has not
been used for some time.
HOSE AND HOSE CONNECTION
The air supply hose is 3/8" I.D. If extension hose is neces-
sary, use 1/2" hose, with couplings not less than
3/8" I.D.
LUBRICATION
An oil supply to the air motor is important. SIOUX air line
lubricators are recommended. Adjust to deliver 1-2 drops
of SIOUX Air Motor Oil No. 288 per minute. When air line
lubricator is not used, squirt 10-16 drops directly in the air
inlet twice daily.
