Compressor Controls - Porter-Cable PXCM302 Instruction Manual

A
PART DESCRIPTION
A ON ( I )/OFF ( 0 ) Switch: Turn this switch in the "ON ( I )" position to provide automatic
power to the pressure switch and "OFF ( O )" to remove power at the end of each use.
B Safety Valve: If the pressure switch does not shut off the air compressor at its "cut-out"
pressure setting, the safety valve will protect against high pressure by "popping out" at its
factory set pressure (slightly higher than the pressure switch "cut-out" setting).
C Tank Pressure Gauge: The tank pressure gauge indicates the reserve air pressure in the
tank.
D Air Compressor Pump: 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.
E 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.
F 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.
G Thermal Overload Reset: (not shown) This motor has a manual 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. Turn the air compressor OFF ( O ).
2. Unplug air compressor and wait until compressor cools down.
3. Plug the air compressor into an approved outlet.
4. Turn the air compressor ON ( I ).
H Regulator: Valve used to ensure that the tank pressure never reaches unsafe levels. It also
allows the user to adjust the pressure coming out of the tank to match what is needed for the
task
I Pressure Regulator Gauge: The gauge that indicates the amount of pressure that the
regulator is providing to the tool.
J Quick Connects: Fittings that are designed to accept a hose that allows pressure to be
released for tool usage.
