condensation at the end of each use.

Break-in Procedure

Risk of Unsafe Operation. Serious damage may result if the following break-in instructions are not closely followed.

This procedure is required before the air compressor is put into service and when the check valve or a complete compressor pump has been replaced.

1.Make sure the On/Off switch is in the OFF (O) position.

2.Plug the power cord into the correct branch circuit receptacle. (Refer to "Voltage and Circuit Protection" paragraph in the "Installation" section of this manual.)

3.Open the drain valve (counter- clockwise) fully to permit air to escape and prevent air pressure build up in the air tank during the break-in period.

4.Move the On/Off switch to ON (I) position. The compressor will start.

5.Run the compressor for 15 minutes. Make sure the drain valve is open and there is minimal air pressure build-up in tank.

6.After 15 minutes, close the drain valve by turning clockwise. The air receiver will fill to "cut-out" pressure and the motor will stop.

The compressor is now ready for use.

Before Each Start-Up:

1.Set the On/Off switch to OFF (O).

2.Pull the regulator knob out and turn counterclockwise to set the outlet pressure to zero.

3.Attach hose and accessories.

NOTE: The hose or accessory will require a quick connect plug if the air outlet is equipped with a quick connect socket.
