Porter-Cable Air Compressor instruction manual Pressure Release Valve The pressure, How to Stop

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
	Valve
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.
Pressure Release Valve: The pressure
	Pressure
release valve located on the side of the
	Release
pressure switch, is designed to
	Valve
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: 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.
