Maintenance - Porter-Cable PXCMSAC420VW Instruction Manual

To avoid personal injury, always shut off and unplug the compressor and relieve all
air pressure from the system before performing any service on the air compressor.
Regular maintenance will ensure trouble free operation. Your electric powered air
compressor represents high quality engineering and construction; however, even
high quality machinery requires periodic maintenance. The items listed below
should be inspected on a regular basis.
DRAINING THE TANK
vent corrosion of the tank from the inside, this moisture must be
drained at the end of every workday. Be sure to wear protective
eyewear. Relieve the air pressure in the system and open the
drain valve on the bottom of the tank and tilt tank to drain.
NOTE: In cold climates, drain the tank after each use to reduce problems with
freezing of water condensation.
CHECKING THE RELIEF VALVE
Pull the relief valve daily to ensure that it is operating properly and to clear the valve
of any possible obstructions. Check that all connections are tight. A small leak in
any of the hoses, transfer tubes, or pipe connections will substantially reduce the
performance of your air compressor.
TESTING FOR LEAKS
If you suspect a leak, spray a small amount of soapy water around the area of the
suspected leak with a spray bottle. If bubbles appear, repair or replace the faulty
component. Do not overtighten any connections.
STORAGE
Before storing the compressor for a prolonged period, use an air blow gun to clean
all dust and debris from the compressor. Disconnect the power cord and coil it up
on handle. Pull the pressure relief valve to release all pressure from the tank. Drain
all moisture from the tank. Cover the entire unit to protect it from moisture and dust.
