Regulator: Controls the air
pressure shown on the outlet
pressure gauge. Turn regulator knob
clockwise to increase pressure
and counterclockwise to decrease
pressure.
Quick Connect Body: The quick
connect body accepts Industrial quick
connect plugs to make connections
simple and easy.
Cooling System (not shown): This
compressor contains an advanced
design cooling system. At the heart of
this cooling system is an engineered
fan. It is perfectly normal for this fan
to blow air through the vent holes
in large amounts. You know that the
cooling system is working when air is
being expelled.
Air Compressor Pump (not shown):
Compresses air into the air tank.
Working air is not available until the
compressor has raised the air tank
pressure above that required at the
air outlet.
Description of Operation
Become familiar with these controls
before operating the unit.
On/Auto/Off Switch: Turn this switch
"On/Auto" to provide automatic power
to the pressure switch and "Off" to
remove power at the end of each use.
Pressure Switch: The pressure
switch automatically starts the
motor when the air tank pressure
drops below the factory set "cut-in"
pressure. It stops the motor when the
air tank pressure reaches the factory
set "cut-out" pressure.
Safety Valve: If the pressure switch
does not shut Off the air compressor
at its "cut-out" pressure setting, the
safety valve will protect against high
pressure by "popping out" at its factory
set pressure (slightly higher than the
pressure switch "cut-out" setting).
Tank Pressure Gauge: The tank
pressure gauge indicates the reserve
air pressure in the tank.
Outlet Pressure Gauge: The outlet
pressure gauge indicates the air
pressure available at the outlet side of
the regulator. This pressure is controlled
by the regulator and is always less than
or equal to the tank pressure.
