INSTRUCTIONS & PARTS LIST
FOR 1446HPL AIR SHEAR
AIR SUPPLY
The efficiency and life of this tool depends on the proper supply of
clean, dry, lubricated air at about 90 Ibs. P.S.I., although higher or
lower pressures may be used. The use of an air line filter,
pressure regulator and lubricator is recommended.
Before connecting the tool, blow the air line to remove water and
dirt which may have accumulated. This is especially 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 necessary,
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 lubrica-
tors are recommended. Adjust to deliver 2 drops of SIOUX Air
Motor Oil No. 288 per minute. When air line lubricator is not used
squirt several drops of oil into the air inlet before using. Gear case
and Shear head must be lubricated after every 40 hours of
operation with SIOUX Grease No. 289A.
