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, restrictions in air pipes, 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 tool daily with a good grade of air tool oil. If no
air line oiler is used, run a 1/2 ounce 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.
