General Information
To use the compressor, start the vehicle engine
and engage the hydraulic system. The
compressor can now be activated using the
compressor switch. This energizes the hydraulic
solenoid sending oil to the hydraulic drive motor
and starts the compressor. Through the air
pressure switch and pilot valve, the system will
now function automatically. Once engaged,
adjust the engine speed control to ensure that
the compressor speed does not exceed 1000
RPM under load. Adjustment instructions are
provided with the speed control unit.
Air Pilot Valve Operation (Head Unloading
System)
When the hydraulic system is engaged the
compressor will pump air into the receiver until
the pressure reaches 175 psi. At this time the
air pilot valve senses the pressure in the
receiver and engages an intake valve hold-open
mechanism. The compressor will run free until
the pressure in the receiver falls below 145 psi
and the air pressure valve disengages the
intake valve hold-open mechanism to allow the
Operation
Each compressor is bench tested under load at the factory to ensure proper break-in and operation.
While it is not necessary to follow any break-in procedure, the following checks should be made
before putting the unit into service and periodically during use.
compressor to pump air. See head unloading

Operating Notes
This reciprocating compressor must not be used
for breathing air. To do so will cause serious
injury whether air is supplied direct from the
compressor source or to breathing tanks for
later use. Any and all liabilities for damage or
loss due to injuries, death and/or property
damage, including consequential damages
stemming from the use of this compressor to
supply breathing air will be disclaimed by the
manufacturer.
The use of this compressor as a booster pump
and/or to compress a medium other than
atmospheric air is strictly non-approved and can
result in equipment damage and/or injury. Non-
approved uses will also void the warranty.
Never use plastic pipe or improperly rated metal
pipe. Improper piping materials can burst and
cause injury or property damage.
Before Start-Up
Inspect unit for any visible signs of damage.
Check the oil level in the compressor with the dipstick on the unit. If oil is needed, use American
Eagle synthetic compressor oil (P/N C0087) or an equivalent synthetic oil.
Note: There may be oil
left in the crankcase from the factory bench test. Overfilling may cause the compressor to
back blow oil. Always check the oil level and fill to the designated marking on the dipstick
before putting the unit into service.
Check hoses (air and hydraulic) for weak or worn condition and make sure that all connections are
secure.
Check the air intake filters on each head to make certain that they are clean and unobstructed.
Dirty air filters are a possible cause of reduced air output.
