Operation 9
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 compressor to pump air.
See head unloading system for detailed views and
adjustment instructions on the next page.
Hydraulic otor Bypass Circuit
The hydraulic motor is equipped with a bypass circuit
which protects the compressor from over speed.
When the compressor is pumping, all hydraulic oil
flows through the hydraulic motor. When the
compressor is running free, some oil is bypassed
around the hydraulic motor preventing the
compressor from speeding up until the engine speed
control disengages. The bypass circuit, in conjunction
with the engine speed control will cause the
compressor to turn very slowly when not pumping.
This is normal operation. When air is again required,
the engine speed control engages, the bypass circuit
closes and the compressor will operate at speed. The
bypass circuit is set at the factory, no adjustment is
necessary.
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.
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.

while the compressor is running.
1.) Loosen locknut (D) and back off several turns. Do
not turn differential adjuster (C).
2.) Check reading on the tank pressure gauge. Set the
compressor maximum pressure at 175 psi. Over
pressurizing compressor will cause damage and
void warranty. Turn threaded cap (A) clockwise to
increase pressure or counterclockwise to decrease
pressure.
3.) After pressure is set, tighten locknut (D). Be careful
not to move the threaded cap (A).
Differential Pressure Adjustment: Proceed with the
following while the compressor is running.
1.) Loosen locknut (B) 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 (C) clockwise to
increase differential pressure or counterclockwise to
decrease differential pressure.
3.) After pressure is set, tighten locknut (B). Be careful
not to move nut (C)

Maintenance 11
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 13
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.
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.
CO PONENT INSTALLATION
This section pertains to the installation of the air compressor, PTO, pump and other related items.

Hydraulic System:
Installed on the compressor are bulkhead fittings to which hydraulic lines are attached. To the
appropriate fitting (see drawing detailing front of compressor), a 1/2” high-pressure hose must be
attached. This hose comes from the hydraulic pumps pressure side. A 1-1/4” hydraulic suction hose
must be installed from the hydraulic reservoir to the hydraulic pump. (See drawing above) ote: For
compressors purchased without a reservoir a 3/4” minimum low-pressure return line is connected to
the hydraulic return fitting and is routed to the oil reservoir through a filter. The case drain line from
the hydraulic motor is also routed to the oil reservoir (DO OT I STALL A FILTER O THE CASE
DRAI LI E). American Eagle recommends a sufficient sized reservoir be provided which includes
the proper suction and return filters. The cooler on 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 3/4”(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.
