DESCRIPTION OF OPERATION
Become familiar with these controls before operating the unit.
On/Auto(I)/Off(0) Switch: Turn this switch "On/Auto (I)" to provide automatic
power to the pressure switch and "Off (O)" 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 pres-
sure in the tank.
Globe Valve: Opens and closes air discharge valve. Turn knob counter-clockwise
to open and clockwise to close.
Regulator (sold separately, not shown): An air pressure regulator or a separate
air transformer which combines the functions of air regulation and/or moisture and
dirt removal is recommended for most applications.
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 per-
fectly 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.
