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
system for detailed views and adjustment
instructions the following page.
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. on-
approved uses will also void the warranty.
ever 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/ 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.

pressure or counterclockwise to decrease pressure.
3.) After pressure is set, tighten locknut
4.) Be careful not to move the threaded cap (1).
Differential Pressure Adjustment: Proceed with the
following while the compressor is running.
1.) Loosen locknut (2) and back off several turns.
2.) Check reading on the tank pressure gauge. Set the
pressure to 30 psi differential (unload at 175 psi, reload
at 145 psi). Turn nut (3) clockwise to increase
differential pressure or counterclockwise to decrease
differential pressure.
3.) After pressure is set, tighten locknut (2). Be careful
not to move nut (3)

Maintenance
The following table is a list of routine maintenance items, including service intervals. Service
intervals are listed as hours, days, or weeks, whichever occurs first. American Eagle recommends
that these service intervals be followed. Before performing any maintenance function “Lock Out” or
“Tag Out” all sources of power. Be sure all air pressure in unit is relieved. Failure to do so may
result in injury or equipment damage.
Under normal operating conditions, oil changes are required every 3 months. When operating in a
dirty environment, change the oil more frequently as your particular operating condition dictates.
General preventative maintenance includes maintaining proper fluid level in both systems and the
general cleanliness of the equipment. Proper fluids according to the specifications are required.

Installation
Pump Assembly:
The pump assembly may either be installed
directly on the PTO or as an optional method,
may be driven by a driveline from the PTO.
Pump manufacturers provide specific installation
information for their products and should be
consulted if questions arise.
PTO Assembly:
Check with the PTO manufactures
representative for specific instructions regarding
your particular make, model, and year of
vehicle. As some trucks may require
modification of the transmission cross member
and the exhaust system, the manufacturer’s
instructions should be followed to insure proper
installation of the PTO.
Compressor Assembly:
Prepare the mounting location of the
compressor by locating and drilling four (4)
holes, 9/16” diameter as per the mounting
pattern of the air compressor base. Using four
(4) 1/2” x 1.50 GR-5 cap screws,1/2” flat
washer, and 1/2” nyloc nut, secure the
compressor in place. The compressor is air
cooled, and must have a clean supply of cooling
air to the fan with minimum restrictions.
Adequate space must be provided for proper
circulation of air.
Electrical Connections:
From the solenoid valve (located on the
hydraulic manifold) there are two (2) wires, red
and black, running to the compressor pressure
switch. Connect the black wire to the vehicle
frame or other suitable ground. The red wire
mounts to the pressure switch as shown. Install
a toggle switch in a convenient location.
Connect one terminal to the compressor
pressure switch and the other terminal to a 12-
volt power supply. Add a 20 amp fuse between
the battery and switch. A third wire is required
from the air compressor pressure switch when
connecting the speed control into the system.
(See drawing below)
Electric speed control:
An optional electric or electronic speed control
must be used to maintain proper operating
speed of the air compressor. The engine speed
control will automatically increase from idle to a
preset speed when engaged and decrease
when disengaged. The electric speed control
(American Eagle P/ C0873) is used on most
gasoline engines. The electronic speed controls
are used only on Ford 6.0 and 7.3L diesel
engines. Proper installation instructions are
provided with each system.
COMPONENT INSTA ATION
This section pertains to the installation of the air compressor, PTO, pump and other related items.
The instructions are intended as a guide to assist you with particular installation. These instructions
will provide only general information.

Hydraulic System:
Installed on the compressor is a valve block assembly that controls the flow to the hydraulic
motor. To this block, a 3/4” high-pressure hose and a 3/4” return line must be attached. (See
drawing above) ote: The case drain line from the hydraulic motor is also routed to the oil
reservoir. American Eagle recommends a sufficient sized reservoir be provided which includes
the proper suction and return filters. The optional cooler on some versions of the compressor
is designed and sized to cool the air compressor efficiently. An auxillary oil cooler is required
when additional hydraulically operated equipment are added to the hydraulic system.
Pressure on the return line exceeding 200 PSI can and will cause damage to the filter, cooler,
and components of the compressor hydraulic system.

Air System:
Two (2) airlines must be routed to the air tank for
proper installation. The main airline is routed from
the check valve to the air tank using a 1-
1/4”(200psi) air hose. This is the main delivery line
and should be free from all obstructions. A 1/4” line
is routed from the air pressure valve to the air
tank. This line senses the pressure in the tank and
will engage and disengage the compressor
automatically.
