OPERATING INSTRUCTIONS
COMPRESSOR CONTROLS
(Figure 5)
Pressure Switch (A): This switch turns on the compressor. It is operated manually,
but when in the AUTO position, it allows the compressor to start up or shut down
automatically, without warning, upon air demand. ALWAYS set this switch to OFF
when the compressor is not being used, and before unplugging the compressor.
Pressure Relief Valve (B): If the pressure switch does not shut down the motor
when pressure reaches the preset level, this valve will pop open automatically to
prevent over pressurization. To operate manually, pull the ring on the valve to relieve
air pressure in the tank.
Tank Pressure Gauge (C): This gauge measures the pressure level of the air stored
in the tank. It is not adjustable by the operator, and does not indicate line pressure.
Air Pressure Regulator (D): This air pressure regulator enables you to adjust line
pressure to the tool you are using.
Never exceed the maximum working pressure of the tool. Turn the knob clockwise
to increase pressure, and counterclockwise to decrease pressure.
Regulated pressure gauge (E): Measures the regulated outlet pressure.
Quick connector (F): Connect air hose to this outlet.
