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 (counter-
clockwise.
Risk of Bursting.

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 (clockwise).
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.
To Check Safety Valve
Risk of Bursting.
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.

is on. When servicing, you may
be exposed to voltage sources,
compressed air, or moving parts.
Before servicing unit unplug or
disconnect electrical supply to
the air compressor, bleed tank
of pressure, and allow the air
compressor to cool.
