OPERATION
 Control the amount of air flow with the pressure regula-
tor knob. Turning the knob fully counterclockwise will
completely stop the flow of air.
NOTE: Always use the minimum amount of pressure
necessary for your application. Using a higher pressure
than needed will drain air from the tank more rapidly and
cause the unit to cycle on more frequently.
 When finished, always drain the tank and unplug the
unit. Never leave the unit plugged in and/or running
unattended.
DRAINING THE TANKS
See Figure 14, page 23.
To help prevent tank corrosion and keep moisture out of the
air used, the air tanks of the compressor should be drained
daily.
NOTE: The air compressor has three tanks and three drain
valves. Be sure to open drain valves for all three tanks and
perform this operation for all tanks.
To drain:
 Turn the air compressor off.
 Pull the rings on the pressure relief valves to release until
tank pressure gauges read less than 20 psi.
 Release the rings.
 Rotate drain valves counterclockwise to open.
 Tilt tank to drain moisture from tank into a suitable
container.
NOTE: Condensate is a polluting material and should be
disposed of in compliance with local regulations.
 If drain valves are clogged, release all air pressure, remove
and clean valves, then reinstall.
WARNING:
Unplug the air compressor and release all air from
the tanks before servicing. Failure to depressurize
tanks before attempting to remove valve can cause
serious personal injury.
 Rotate drain valves clockwise until tightly closed.
CHECKING THE SAFETY VALVES
See Figure 15, page 23.
DANGER:
Do not attempt to tamper with the safety valves.
Anything loosened from this device could fly up
and hit you. Failure to heed this warning could
result in death or serious personal injury.
Safety valves will automatically release air if the air tank
pressure exceeds the preset maximum. The valves should be
checked before each day of use by pulling the ring by hand.
NOTE: The air compressor has two pressure relief valves.
Be sure to open both pressure relief valves.
 Turn the air compressor on and allow the tanks to fill. The
compressor will shut off when the pressure reaches the
preset maximum.
 Turn the air compressor off.
 Pull the rings on both safety valves to release air for three
to five seconds.
WARNING:
If air leaks after the ring has been released, or if
the valve is stuck and cannot be actuated by the
ring, do not use the air compressor until the safety
valve has been replaced. Use of the air compressor
in this condition could result in serious personal
injury.
RESET BUTTON
See Figure 16, page 23.
When amperage into the air compressor exceeds the
specified amperage, the air compressor will automatically
shut off.
To reset the air compressor:
 Turn the air compressor off.
 Unplug the air compressor.
 Press the reset button.
 Plug the air compressor into an approved outlet.
 Turn the air compressor on.
NOTICE:
Do not operate the air compressor without an air
filter in place. Doing so can damage the unit.
INSTALLING THE HIGH FLOW AIR FILTER
See Figure 17, page 23.
An easy start air filter is factory installed on the air
compressor. If an increase in performance is needed for
your application, you may achieve better results with the
high flow air filter.
The high flow filter is packed separately with the unit.
 Turn the air compressor off.
 Unplug the air compressor.
 Turn the easy start air filter and adaptor counterclockwise
to remove.
