MAINTENANCE AND INSPECTION INSTRUCTIONS
Disconnect, tag and lock out power source then release all pressure from the system before
attempting to install, service, relocate or perform any maintenance.
All repairs should be performed by an authorized service representative.
In order to maintain efficient operation of the compressor system,
check the air filter and oil level before each use. The ASME safety
valve should also be checked daily (see Figure 18). Pull ring on
safety valve and allow the ring to snap back to normal position.
This valve automatically releases air if the tank pressure exceeds
the preset maximum. If air leaks after the ring has been released,
or the valve is stuck and cannot be actuated by the ring, the ASME
safety valve must be replaced.
Do not tamper with the ASME safety valve.
Tank
Never attempt to repair or modify a tank! Welding, drilling or any other modification will
weaken the tank resulting in damage from rupture or explosion. Always replace worn, cracked
or damaged tanks.
Drain liquid from tank daily.
Drain Tank: Disconnect, tag and lock out power source; release pressure. Drain moisture from tank by
opening drain valve underneath tank once tank pressure is less than 40 PSI (See Figure 16 on page 13).
The tank should be carefully inspected at a minimum of once a year. Look for cracks forming near the
welds. If a crack is detected, remove pressure from tank immediately and replace.
Compressor Lubrication
See Installation. Add oil as required. The oil should be changed every three months or after every 200 hours
of operation; whichever comes first.
If the compressor is run under humid conditions for short periods of time, the humidity will condense in
the crankcase and cause the oil to look creamy. Oil contaminated by condensed water will not provide
adequate lubrication and must be changed immediately. Using contaminated oil will damage bearings,
pistons, cylinders and rings and is not covered under warranty. To avoid water condensation in the oil,
periodically run the compressor with tank pressure near 120 PSI for 2-stage compressors by opening the
drain cock or an air valve connected to the tank or hose. Run the pump for an hour at a time at least once a
week or more often if the condensation reoccurs.
IMPORTANT:
Change oil after first 50 hours of operation.
Air Filter
Never run the compressor pump without an intake air filter or
with a clogged intake air filter. The air filter element should be
checked monthly (see Figure 19). Operating compressor with
a dirty filter can cause high oil consumption and increase oil
contamination in the discharge air. If the air filter is dirty it must
be replaced.
