PART NAME

Electric Motor

Air Compressor Pump

PART DESCRIPTION

The motor is used to power the pump. It contains a thermal overload protector. If the motor overheats for any reason, the thermal overload protector will shut it down in order to prevent the motor from being damaged.

The pump is used to compress the air and discharge it into the tank via the piston moving up and down in the cylinder.

C

Air Tank

Tank Pressure Gauge

The tank is used to store the compressed air.

The gauge is used to measure the stored air pressure level of

the tank. It is not adjustable by the operator and does not

indicate line pressure.

D Air Pressure Regulator

The regulator is used to adjust line pressure to the tool you are

using. Turn the knob clockwise to increase pressure and

counterclockwise to decrease pressure.

E Regulated Pressure Gauge

The gauge is used to measure the regulated outlet pressure.

For this compressor, the quick coupler is also used as the air line outlet. The outlet is used to connect the 1/4 in. NPT air hose.

The drain valve is used to remove moisture from the air tank

after the unit is shut off.

The valve is used to prevent system failures by relieving pressure from the system. If the pressure reaches the preset level and the pressure switch will not shut down the motor, it will automatically pop open. You can also pull the ring on the valve to open.

This switch turns on the compressor and is operated manually.

When in the ON 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.

This product is for use on a nominal 120-volt circuit and should be grounded. A cord with a grounding plug as illustrated must be used. Make sure that the product is connected to an outlet that has the same configuration as the plug. No adapter should be used with this product.
