INSTALLATION
Air Supply
The recommended hook-up is shown in Figure A. Pneumatic tools
operate on a wide range of air pressures. For maximum efficiency
and longer tool life, the pressure of the air supplied to these
tools MUST not exceed the rated PSI at the tool when the tool is
running. Using a higher than rated pressure will cause faster wear
and drastically shorten the tool’s life. A higher air pressure can also
cause an unsafe condition and explosion.
The inside diameter of the hose 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 1/4” NPT thread.
The use of air line lubricators and air line
filters is recommended to prevent water
in the line that can damage the tool. Drain
the air tank daily. Clean the air inlet filter
screen on at least a weekly schedule to
remove accumulated dirt or other matter
that can restrict air flow.
The tool’s air inlet used for connecting
an air supply has standard 1/4” NPT
American thread.
Safety Rules For Pneumatic Tools
1) Inspect the air hose for cracks or other problems.
Replace the hose if worn.
2) Never point an air hose at another person.
3) Disconnect the tool when not in use, or before performing
service or changing accessories.
4) Use proper hoses and fittings. Never use quick change
couplings attached to the tool. Instead, add a hose and
coupling between the tool and the air supply.
