AIR SUPPLY
Tools of this class operate on a wide range of air pressures. It is
recommended that air pressure of these tools not exceed 90 psig
with trigger fully depressed and no load applied to the tool. Higher
pressure and unclean air will shorten tool life and may create a
hazardous condition.
Water in the air line will cause damage to the tool. Drain
the water from air lines and compressor prior to
running tool. Clean the air inlet filter screen weekly.
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.
Ensure an accessible emergency shut off valve has been installed
in the air supply line and make others aware of its location.
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 Matco authorized service center.
LUBRICATION & MAINTENANCE
Lubricate the air motor daily with high quality air tool oil. If no air
line oiler is used, run 1/2 oz. of oil through the tool. The oil can
be squirted into the tool air inlet 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.
After an air tool has been lubricated, oil will discharge through
the exhaust port during the first few seconds of operation. The
exhaust port must be covered with a towel before applying air
pressure to prevent serious injury.

or similar grease kit .
Always turn off the air supply, drain hose of air pressure and detach tool from air
supply before installing, removing or adjusting any part or accessory on this tool,
or before performing any maintenance on this tool.
NOTE:
During operation, safety goggles should always be worn to guard against
flying rust and chips (users & bystanders).
