Description of Operation
Become familiar with these controls
before operating the unit.
On/Auto/Off Switch: Turn this switch
ON 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 outtet
pressure gauge indicates the air
pressure avaiIabb at the outlet side
of the regulator. This pressure is
controlled by the regulator and is
always less than or equa! 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 outIet pressure
gauge. Pull the knob out and turn
cIockwise to increase pressure
and counterclockwise to decrease
pressure.
When the
desired
pressure
is reached
push knob Valve
in to Iock in
place.
Drain Vamve:The drain valve is
located at the base of the air tank
and is used to drain condensation at
the end of each use.
Cooming 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 norma! for this fan
to blow air through the vent hobs
in large amounts. You know that the
cooling system is working when air is
being expelled.
A08597 12-ENG
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

Cheek Valve: When the air
compressor is operating, the check
valve is "open", allowing compressed
air to enter the air tank. When the
air compressor reaches "cut-out"
pressure, the check valve "closes",
allowing air pressure to remain inside
the air tank.
