Porter-Cable N020206-NOV08-0, C7501M How to Use Your Unit, How to Stop, Before Starting

Check 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.

Valve

Pressure Release Valve: The pressure release valve located on the side of the pressure switch, is designed to automatically release compressed air from the compressor head and the outlet tube when the air compressor reaches "cut-out" pressure or is shut off. The pressure release valve allows the motor to restart freely. When the motor stops running, air will be heard escaping from this valve for a few seconds. No air should be heard leaking when the motor is running or after the unit reaches "cut-out" pressure.

Motor Overload Protector: This motor has a manual thermal overload protec- tor. If the motor overheats for any reason, the overload protector will shut off the motor. The motor must be allowed to cool down before restarting. To restart:

1.Place the Auto/Off lever in the "Off" position.

2.Allow the motor to cool.

3.Depress the red reset button on the motor.

4.Place the Auto/Off lever in the "Auto" postion to restart the motor.

Air Intake Filter (not shown): This filter is designed to clean air coming into the pump. This filter must always be clean and ventilation openings free from obstructions. See "Maintenance".

How to Use Your Unit

How to Stop:

1.Set the Auto/Off lever to "Off".

Before Starting

Do not operate this unit until you read and understand this instruction manual for safety, operation and maintenance instructions.

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 Auto/Off lever is in the "Off" position.

2.Check oil level in pump. See Oil paragraph in the Maintenance section for instructions.

3.Recheck all wiring. Make sure wires are secure at all terminals connections. Make sure all contacts move freely and are not obstructed.

4.Open the globe valve fully to permit air to escape and prevent air pressure build up in the air tank during the break-in period.

5.Move the Auto/Off lever to "Auto" position. The compressor will start.

6.Run the compressor for 20 minutes. Make sure the globe valve is open and there is minimal air pressure build-up in tank.
