CAT-375 3/4" HD Impact Wrench
AIR SUPPLY
Tools of this class operate on a wide range of air pressures. It is
recommended that air pressure of these tools measures 90 PSI
at the tool while running free. Higher pressure and unclean air
will shorten tool life because of faster wear and may create a
hazardous condition.
Water in the air line will cause damage to the tool. Drain the air
tank daily. Clean the air inlet filter screen on at least a weekly
schedule. The recommended hook-up procedure can be viewed
in Figure 1.
The air inlet (Figure 2), used for connecting air supply, has standard
1/4" NPT American Thread.
Line pressure should be increased to compensate for unusually
long air hoses (over 25 feet). Minimum hose diameter should be
3/8" I.D. and fittings should have the same inside dimensions.
TROUBLESHOOTING
Other factors outside the tool may cause loss of power or erratic
action. Reduced compressor output, excessive drain on the air line,
moisture or restrictions in air pipes or the use of hose connections
of improper size or poor conditions may reduce air supply. If
outside conditions are in order, and the tool still performs erratically,
disconnect tool from hose and take tool to your nearest Cornwell
Tools authorized service center.
LUBRICATION & MAINTENANCE
Lubricate the tool daily with a good grade of air tool oil. If no
air line oiler is used, run a teaspoon of oil through the tool. The oil
can be squirted into the tool air inlet Figure 2, or into the hose at
the nearest connection to the air supply, then run the tool. A rust
inhibitive oil is acceptable for air tools.
