provide safe and dependable service if
operated according to instructions. Read
and understand the safety precautions given
in this manual and on the decals attached to
the shields. Failure to do so can result in
personal injury or equipment damage.
perators and maintenance personnel must
always comply with the safety precautions.
These precautions are given here for your
safety. Review them carefully before operat-
ing the compressor and before performing
maintenance or repairs.
Supervising personnel should develop addi-
tional precautions relating to the specific
work area and local safety regulations.
Precautions
Always wear safety equipment such as gog-
gles, ear plugs and head protection at all
times when operating the compressor.
Do not inspect or clean the compressor while
the power source is connected. Accidental
engagement of the tool can cause serious
injury.
Before performing any maintenance on the
compressor, place a warning tag on the
hydraulic power source or disconnect the
hoses from the compressor motor to prevent
accidental startup of the compressor.
Always connect hoses to the compressor
before energizing the power source. Be sure
all hose connections are tight.

Chapter 3 - Operation
Before Start-Up
Inspect unit for any visible signs of damage.
Check the oil level in the compressor (See Section “Changing the il”). If oil is needed,
use American Eagle synthetic compressor oil (P/N C0087) or an equivalent synthetic oil.
Check hoses (air and hydraulic) for weak or worn condition and make sure that all con-
nections are secure.
Check the air intake filter to make certain that it is clean and unobstructed. A dirty air filter
is a possible cause of reduced air output.
Each compressor is bench tested under load at the factory to ensure proper 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.
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 com-
pressor. The system will now function auto-
matically. nce engaged, adjust the
engine speed control to ensure that the
compressor speed does not exceed 8000
Rpm under load. Adjustment instructions are
provided with the speed control unit.
Air Operations(SRS-65RP & SRS-65E)
Activating the compressor switch sends
power to the cooling fan, hydraulic solenoid
valve and normally closed terminal (87A)
on the Bosch relay. The normally open
hydraulic solenoid valve closes, sending
hydraulic oil to the motor operating the
compressor. The fan and compressor oper-
ate whenever the hydraulic system is
engaged and the compressor switch is on.
Power from the common terminal (30) on
the Bosch relay goes to the line terminals on
the compressor pressure switch. If the air
pressure is below the kick out pressure (115
psi minimum/120 psi maximum) the pressure
switch closes sending power to the engine
speed control and compressor air inlet sole-
noid valve. The engine speeds up and the
compressor begins pumping air. When the
air pressure reaches the kick out pressure
setting (145 psi minimum/150 psi maximum)
the pressure switch opens, shutting the air
inlet valve and deactivating the speed
control.
The compressor is protected by an air pres-
sure and compressor oil switch gauge. The
coil on the Bosch relay is grounded through
these two switch gauges. If the air pressure
or compressor oil temperature exceeds the
switch gauge settings they close, complet-
ing the circuit and energizing the relay coil.
The normally closed switch on the Bosch
relay opens cutting power to the compres-
sor pressure switch. The compressor stops
pumping air and the engine slows down.
The switch gauges are set at the factory
and should not be adjusted.

SRS-65 Owne ’s Manual
Air Operations (SRS-65P)
Activating the compressor switch sends
power to the cooling fan and normally
closed terminal (87A) of the Bosch relay.
Power from the Bosch relay goes to the
hydraulic solenoid valve and speed control.
The compressor and speed control are acti-
vated any time the hydraulic system is
engaged and the compressor switch is on.
The compressor pumps air until the pressure
reaches 175 psi. The proportional compres-
sor inlet valve then shuts down and only
allows in sufficient air to maintain 175 psi.
This pressure will be maintained as long as
the air usage remains within the capacity of
the compressor. The inlet valve is controlled
by the compressors pneumatic control cir-
cuit. The air pressure is factory set and
needs no further adjustment. The pneumati-
cally controlled compressor is also protect-
ed by two switch gauges. If the air pressure
or oil temperature exceeds the preset val-
ues, the switch closes energizing the relay
coil which opens the normally closed switch
on the relay shutting off power to the
hydraulic solenoid and speed control.
Operating otes:
This rotary screw 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 conse-
quential 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.

Chapter 4 - 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 recom-
mends that these service intervals be followed. Before performing any maintenance func-
tion, turn off compressor, hydraulic system, truck engine and remove keys to assure that
compressor is not started. Be sure all air pressure in unit is relieved. Failure to do so may
result in injury or equipment damage.
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.

Service Intervals

SRS-65 Owne ’s Manual
The oil level in the compressor case is an important factor for the operational reliability of
the system.
Check Intervals:
1. Before starting unit.
2. Every 100 operating hours
Check Procedures:
1. Turn off the compressor, hydraulic system and
truck engine to ensure that compressor is not start-
ed.
2. Wait for one full minute.
3. Slowly unscrew the oil fill cap on the compressor
case (also referred to as the separator receiver).
4. Check the oil level.
5. If the oil level is under the minimum level, add oil to maximum level as shown.
6. Replace cap and hand tighten. Unit is ready to be put into service.
ote: The screw-type oil fill cap is has a bleed hole which will release pressure in the com-
pressor case. The bleed hole is exposed after the cap is loosened about two turns. If there
is still pressure in the case, wait a few minutes for it to bleed off.
Condensation Drain
Condensation (water) in the oil affects the operation and life of the screw compressor.
Screw compressors are especially vulnerable due to the fact that the oil is used for both
sealing and lubrication. Both oil and water are removed from the air in the separator car-
tridge and returned to the compressor case. Condensation builds up faster when the com-
pressor is operated intermittently in humid conditions. Under these conditions, the conden-
sate should be drained each day before start up when the compressor is cold.
Possible Malfunctions:
Insufficient lubrication.
Poor air/oil separation and high pressure across the separator cartridge.
Corrosion and rust formation.
Maintenance Procedure
1. Unscrew oil fill cap.
2. Place a container under the oil drain pipe and carefully unscrew the oil drain cap.
3. Drain the water from the compressor case until nothing but oil comes out, replace the
cap and tighten.
4. Fill the compressor case with oil to maximum and replace oil fill cap.
5. Turn on compressor and operate for three minutes.
6. Check oil level and fill if low.
7. Dispose of condensate (mixture on water and oil) in accordance with local and federal
regulations.

Oil Requirements
Screw compressors must be operated using the
most suitable oil for operation. The compressor man-
ufacturer must approve this oil for use. The oil must
also be suitable for use in unfavorable conditions
such as: contamination of the intake air by gases,
solvent vapors, exhaust gases, and high ambient
temperature conditions.
Suitable types and brands of oil may be specified
on request. Suitable screw compressor oils can be
mineral oils, synthetic oils, and biological degrad-
able oils.
The substances and materials used in the compres-
sor such as seals must be taken into account when
selecting the types of oil. Corrosion or other material
degradation must not occur.
Important: Do not mix different types of oil.
Important: In the case of ambient temperatures
close to freezing, prevent the unit from freezing.
Pipeline Materials:
The oil used in screw compressors can degrade
plastics used in air pipelines.

Hydraulic Oil Cooler/Compressor Oil Cooler
For reliable operation and longevity of both compressor and hydraulic system, the cooler
should be kept clean. The compressor system is protected from operation at high temper-
ature by a switch gauge. If the compressor shuts down or is operating close to the shut
down temperature, the cooler should be cleaned. The cooler can be cleaned with com-
pressed air, pressure washer or steam cleaner.
Maintenance Procedure
1. Turn off the compressor, hydraulic system and
truck engine to ensure that compressor is not started.
2. Discharge the receiver.
3. Remove the shroud.
4. Drain oil from the compressor.
5. Disconnect:
a. Lines to the cooler.
b. Lines to the thermo valve.
c. Electrical connection to the fan.
6. Remove the cooler.
7. Remove the fan shroud and fan from the cooler.
8. Cap the hydraulic fittings on the cooler and thermo valve.
9. Clean cooler.
10. Reinstall the cooler in reverse order.
11. Refill with oil.
12. Test run compressor and check operating temperature.
13. Check oil level and fill if necessary.

otice: Read this Page Before Installation of the Compressor
This section pertains to the installation of the
air compressor, PT , pump and other relat-
ed items. The instructions are intended as a
guide to assist you with particular installa-
tion. These instructions will provide only gen-
eral information.
Pump Assembly:
The pump assembly may either be installed
directly on the PT or as an optional
method, may be driven by a driveline from
the PT . Pump manufacturers provide
specific installation information for their
products and should be consulted if
questions arise. Note: A Dual or Tandem
Hydraulic Pump is recommended when
additional hydraulically operated equip-
ment are added to the hydraulic system.
PTO Assembly:
Check with the PT 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
PT .
Compressor Assembly:
Prepare the mounting location of the
compressor by locating and drilling four (4)
holes, 1/2” diameter as per the mounting
pattern of the air compressor base. Using
four (4) 3/8” x 1.25 GR-5 cap screws, 3/8”
flat washer, and 3/8” 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 air pressure switch there are two
(2) wires, red and black, running to the
outside of the compressor housing. Connect
the black wire to the vehicle frame or other
suitable ground. Mount a single throw
toggle switch in a convenient location and
connect the red wire from the compressor
to this switch. Connect the other switch
terminal to a fuse holder and then to a 12-
volt power supply. A third wire is required
from the air compressor switch when
connecting the speed control into the
system. (See drawing on next page)
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 preset speed when
engaged and decrease when disengaged.

The airline is routed using a 3/4” (200 psi) air hose. This delivery line should be free from all
obstructions. When connecting to an air tank (American Eagle recommends a minimum
of a ten gallon air tank be installed to maintain proper operation of the air compressor), a
check valve must be installed.
Air System
The hydraulic system consists of the pump, oil reservoir, filters and hoses. Installed on the
compressor is a valve block assembly that controls the flow to the hydraulic motor. To this
block, a 1/2” high-pressure hose must be attached. This hose comes from the pressure
side of the hydraulic pump. A 3/4” minimum low-pressure return line is connected to the
oil cooler outlet and is routed to the oil reservoir. American Eagle recommends a sufficient
sized reservoir be provided that includes the proper suction and return filters. The cooler
on the compressor is designed and sized to cool the air compressor efficiently. An auxil-
iary 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.
