AUTOMATIC ON/OFF PRESSURE SWITCH:
This compressor is equipped with an automatic on/off pressure switch. The compressor
will only run when the switch is in the “I” (ON) position. Once the tank has reached the desired preset pressure (“cut-out” pres-
sure), the pump motor will automatically shut off. While the switch is in the “I” (ON) position, the pump motor will automatically
turn back on once the pressure in the tank drops below the minimum preset pressure (“cut-in” pressure).
DO NOT LEAVE THE COMPRESSOR UNATTENDED WHILE THE POWER SWITCH IS IN THE “I” (ON) POSITION.
4.
AIR TANK PRESSURE GAUGE:
The tank pressure gauge provides a reading of the air pressure inside of the compressor tank.
5.
PRESSURE REGULATOR:
The regulator allows you to select the amount of air pressure that is output through the air hose into
tools and accessories. Turn the pressure regulator knob clockwise to increase discharge pressure, and counter clockwise to
decrease discharge pressure. Please refer to the air delivery requirements of your tools for the proper pressure settings.
NOTICE:
Be careful not to over tighten pressure regulator knob when it “bottoms out” as this may damage pressure regulator.
6.
OUTLET PRESSURE GAUGE:
The outlet pressure gauge provides a reading of the air pressure at the outlet side of the regulator.
This pressure is controlled by the pressure regulator and is always less than or equal to the air tank pressure.
7.
AIR OUTLET PORT:
The air outlet port is located on the pressure regulator body. This port is threaded to accommodate standard
1/4" NPT (M) air fittings found on air hoses and quick connectors. Use PTFE thread-sealing tape on the threads to make sure you
have an airtight connection.
8.
SAFETY RELIEF VALVE:
This compressor is equipped with a safety relief valve that is designed to prevent system failures by reliev-
ing pressure from the system when the air pressure reaches a predetermined level. The safety relieve valve is preset by the manu-
facturer - DO NOT attempt to modify or remove the safety relief valve.
9.
AIR TANK DRAIN VALVE:
Moisture is produced whenever air is compressed. It is critical to drain water from the air tank on this
compressor frequently. If unit is used only occasionally, tank should be drained after each use and prior to the next use. To drain
the tank, slowly open the tank drain fitting by turning clockwise. Once all moisture has drained out, close the fitting securely. NOTE:
Air tank will not pressurize while drain valve is open.
10. AIR INTAKE FILTER:
This compressor is equipped with an externally accessible air intake filter that is designed to clean air coming
into the pump. The filter element is easily removed for periodic cleaning with warm soapy water. Rinse the filter and air dry before
reinstalling. Replace filter element when necessary.
NOTICE: Remove air inlet dust plug and install air filter as indicated in
assembly instructions before using air compressor.
11. THERMAL SHUTDOWN SWITCH:
The electric motor is equipped with an automatic thermal overload protector. If the unit is over-
heating, the motor will automatically shut down. Turn the unit off and allow the unit to cool for approximately 20 minutes before
turning the unit back to the “I” (ON) position. NOTICE: This air compressor is designed for household use only and is not intended
to operate heavy-duty air tools. If your application's demands exceed the capacity of this air compressor, a larger air compressor
that is matched to your application is recommended. If the unit shuts down again, please call factory customer service at 1-800-
423-3598 for assistance.
12. HANDLE:
Convenient handle for easy transport.
13. WHEELS:
Large diameter wheels for easy mobility.
