MAINTENANCE AND INSPECTION INSTRUCTIONS
maintenance.
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 9). 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.

Tank
Always replace worn, cracked or damaged tanks.
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 single 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 10). 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.
Components
Turn off all power and clean the cylinder head, motor, fan blades, air lines, aftercooler and tank on a monthly
basis.

Disconnect, tag and lock out power source then release all pressure
from the system before attempting to install, service, relocate or perform any
Do not tamper with the ASME safety valve.
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.
Drain liquid from tank daily.
