MAINTENANCE
WARNING! To avoid personal injury, always shut OFF
the main power disconnect 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 the
finest engineering and construction available, however,
even
the
finest
machinery
requires
periodic
maintenance.
The
items
listed
below
should
be
inspected on a regular basis.
DRAINING THE RECEIVER
Condensation will accumulate in the receiver tank. To
reduce 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 petcock on the bottom of the
receiver tank to drain.
CLEANING THE AIR FILTER
A dirty air filter will reduce the compressor’s performance
and life. To avoid any internal contamination of the
compressor
pump,
the
filter
should
be
cleaned
frequently, and replaced on a regular basis See Fig 8.
Paper filters should be replaced when dirty. Foam filters
should be cleaned in warm, soapy water. Do not allow
the filters to become filled with dirt or paint. Direct
exposure to dirty conditions and painting areas will void
your warranty.
TESTING FOR LEAKS
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. If you suspect a leak, spray a small amount
of soapy water around the area with a spray bottle If
bubbles appear, reseal and retighten the connection. Do
not overtighten.
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.
STORAGE
Before storing the compressor for a prolonged period,
use an air blow gun to clean all dust and debris from the
compressor. Shut OFF the main power disconnect. Pull
the pressure relief valve to release all pressure from the
receiver. Drain all moisture from the receiver (see left).
Clean the filter elements and filter housing, replace the
elements if necessary. Drain the oil from the compressor
pump crankcase and replace it with new oil (see oil
specifications on page 12). Cover the entire unit to
protect It from moisture and dust.
