Operation (Continued)
4� Do not alter pressure settings on control valve or governor setting on engine� If
lower pressures are required this should be accomplished with a separate pressure
regulator after the outlet valve�
 Compressorhasamaximumoperatingpressurelimitof175psi(twostage)and
should not be operated beyond this limit�
CRANKCASE BREATHER
During severe operating conditions or initial start-up, some oil may accumulate
at the crankcase breather opening� This is normal and will diminish as the pump
accumulates run time and rings become fully seated�

Maintenance
Disconnect the battery cable on models with electric start
and release all pressure from the system before attempting to
install, service, relocate or perform any 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.Pullringonsafetyvalveandallowtheringtosnapbacktonormal
position(SeeFigure10).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 attempt to 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. Always replace worn, cracked or damaged
tanks.
Drain liquid from tank daily.
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

after every 500 hours of operation; whichever comes first�
IMPORTANT:Thegasolineenginerequiresmorefrequentoilchanges.Readengine
maintenance instructions for other periodic service requirements not covered here�
AIR FILTER
Neverrunthecompressorpumpwithoutanintakeairfilternorwithacloggedintake
air filter� Use compressed air to blow the filter clean� Do not wash or oil the element�
If the filter cannot be blown clean, the filter must be replaced� Operating compressor
with a dirty filter can cause high oil consumption and increase oil contamination in the
discharge air�
INTERCOOLER (TWO-STAGE ONLY)
The intercooler provides cooling to reduce temperature and power consumption�
Intercooler fins are sharp. Always wear gloves and use care when
cleaning or working near the intercooler.

dust and other accumulations from the intercooler fins�
