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).
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.
Tank Pressure Gauge: The tank pressure gauge indicates the reserve air
pressure in the tank.
Regulator: Controls the air pressure shown on the outlet pressure gauge. Turn
the knob clockwise to increase pressure and counterclockwise to decrease
pressure.
Drain Valve: The drain valve is located at the base of
the air tank and is used to drain condensation at the
end of each use.
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.
