Pressure Release Valve The pressure | Porter-Cable Air Compressor

Air Compressor Pump (not shown): Compresses air into the air tank. Working air

is not available until the compressor has raised the air tank pressure above that
required at the air outlet.
Drain Valve: The drain valve is located at the base of the
air tank and is used to drain condensation at the end of
each use.	Drain
Check Valve: When the air compressor is operating, the	Drain

	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: The motor has

a thermal overload protector. 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.Set the Auto/Off switch to "Off" and unplug unit.

2.Allow the motor to cool.

3.Depress the red reset button on the motor.

4.Plug the power cord into the correct branch circuit receptacle.

5.Set the Auto/Off switch to "Auto" position.

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 obstruc- tions. See Maintenance.

Break-in Procedure

Risk of property damage. 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 switch is in the "Off" position.

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