Unit cycles
automatically when
power is on. When performing
maintenance, you may be exposed
to voltage sources, compressed air,
or moving parts. Personal injuries
can occur. Before performing any
maintenance or repair, disconnect
power source from the compressor
and bleed off all air pressure.
NOTE: See "Operation" section for
the location of controls.
To Check Safety Valve
If the safety valve
does not work
properly, over-pressurization may
occur, causing air tank rupture or
an explosion.
1. Before starting compressor, pull
the ring on the safety valve to
make sure that the safety valve
operates freely. If the valve
is stuck or does not operate
smoothly, it must be replaced
with the same type of valve.
To Drain Tank
1. Set the On/Off switch to OFF (O).
2. Turn the regulator knob counter-
clockwise to set the outlet pres-
sure to zero.
3. Remove the air tool or accessory.
4. Pull ring on safety valve allowing
air to bleed from the tank until
tank pressure is approximately 20
psi. Release safety valve ring.
5. Drain water from air tank by
opening drain valve on bottom of
tank.
Water will condense
in the air tank. If
not drained, water will corrode and
weaken the air tank causing a risk
of air tank rupture.
6. After the water has been drained,
close the drain valve. The air
compressor can now be stored.
NOTE: If drain valve is plugged,
release all air pressure. The valve
can then be removed, cleaned, the
reinstalled.
