OPERATION
DRAINING THE TANK
See Figure 10.
To help prevent tank corrosion and keep moisture out
of the air used, the tank of the compressor should be
drained daily.
To drain:
n
Rotate drain valve left to open.
n
Drain moisture from tank into a suitable container.
NOTE:
Condensate is a polluting material and should be
disposed of in compliance with local regulations.
n
If drain valve is clogged, release all air pressure, remove
and clean valve, then reinstall.
WARNING:
Unplug the air compressor and release all air from
the tank before servicing. Failure to depressurize tank
before attempting to remove valve may cause serious
personal injury.
n
Rotate drain valve right until tightly closed.
CHECKING THE SAFETY VALVE
See Figure 11.
DANGER:
Do not attempt to tamper with the safety valve. Any-
thing loosened from this device could fly up and hit
you. Failure to heed this warning could result in death
or serious personal injury.
The safety valve will automatically release air if the air
receiver pressure exceeds the preset maximum. The valve
should be checked before each day of use by pulling the
ring by hand.
n
Turn the air compressor on and allow the tank to fill.
The compressor will shut off when the pressure reach-
es the preset maximum.
n
Turn the air compressor off.
n
Pull the ring on the safety valve to release air for three
to five seconds.
n
Release the ring. Air must immediately stop escaping
when the ring is released. Any continued loss of air
after releasing the safety valve ring indicates a problem
with the safety valve. Discontinue use and seek service
before continued use of the air compressor.
