Compressor Controls - Porter Cable PXCMLC3706056 Manual De Instrucciones

Refer to Fig. 3.
Pressure switch (see A)
This switch turns on the compressor. It is operated manually, but when in the
ON position, it allows the compressor to start up or shut down automatically,
without warning, upon air demand. ALWAYS set this switch to OFF when the
compressor is not being used.
WARNING
⚠
and must never be tampered with.
This switch must not be adjusted by the operator; doing so will void the
warranty. The pressure switch controls the level of air pressure in the tank
by automatically starting and stopping the motor, as required to maintain the
factory preset pressure level.
The pressure switch also automatically bleeds pressure from the pump head
when the pump stops. This feature eliminates back pressure in the pump,
ensuring easier starting.
Tank Safety Valve (see B)
Used to allow tank pressure to escape into the atmosphere. If the pressure
switch does not shut off the compressor at it's "cut-out" pressure setting, the
safety valve will protect against high pressure by releasing tank pressure at it's
factory set pressure (slightly higher than the pressure switch "cut-out" setting).
To operate manually, pull the ring on the valve to relieve air pressure in the tank.
Pressure Release Valve (see C)
The pressure release valve (located on the bottom of the pressure switch), is
designed to release compressed air from the compressor head and outlet tube
when the compressor reaches "cut-out" or is shut off. The pressure 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 brief release after reaching "cut-out" pressure.
Tank Pressure Gauge (see D)
This gauge measures the pressure level of the air stored in the tank. It is not
adjustable by the operator, and does not indicate line pressure.
