Safety

This manual contains vital information for the safe use and efficient

operation of this unit. Carefully read the operators manual before

starting the unit. Failure to adhere to the instructions could result in

serious bodily injury or property damage.

The SRS-65 Rotary Screw Compressor will
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.

Operators and maintenance personnel must
always comply with the safety precautions.
These precautions are given here for your
safety. Review them carefully before operating
the compressor and before performing
maintenance or repairs.

Supervising personnel should develop additional
precautions relating to the specific work area
and local safety regulations.

Precautions

Always wear safety equipment such as goggles,
ear plugs and head protection at all times when
operating the compressor.

Establish a training program for all operators to
ensure safe operation.

Do not operate the compressor unless
thoroughly trained or under the supervision of
an instructor.

Do not operate the compressor if it is damaged,
improperly adjusted or not completely or
properly assembled.

Never operate the compressor with any of the
guards removed.

Do not attempt to adjust or disable the
compressors air pressure relief valve. This
valve limits the air pressure to 150 PSI.

The surface of the air compressor and the
plumbing between the compressor and the
cooler may reach temperatures above 150
degrees. Touching these surfaces during
operation can cause burns.

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.

SRS-65 Manual

The air taken in by the air compressor must be
free of flammable fumes and vapors.

Compressor speed should not exceed 8000
RPM.

Use and operate this air compressor only in full
compliance with all pertinent O.S.H.A.
requirements and all Federal, State and Local
codes or requirements.

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.

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.

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.

Note: There may be oil

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 8000
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 150 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 115 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.

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. Non­approved 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.

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.

SRS-65 Oil Level

The oil level in the oil receiver container 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. Switch off the unit with main power and prevent it from accidentally being turned on.

2. Allow one full minute to pass after stopping compressor.

3. Unscrew the cap of the inlet connection pipe with the oil receiver discharged.

4. Check the oil level with the dipstick.

5. Add oil to level if necessary.

6. Tighten cap back into place and unit is ready to be put into service

7. Check for impermeability and replace the o-ring if required.

Note:

• The screw-type cap of the compressor crankcase is equipped with a pressure release hole, which
emits air/oil if the pressure has not been alleviated from the separator receiver. In this case wait a few
minutes for the pressure to release before removing cap totally.

• The oil fill is designed in such a way that the unit cannot be over filled. Any excess oil runs out the fill.

Condensation Drain

The condensation in the oil affects the operation safety and the life of the screw compressor unit.
If you operate the screw compressor unit for a short period of time and therefore at a low operation
temperature, i.e. below the switch temperature of the thermal oil bypass valve, you run the risk of
condensation collecting in the oil separator receiver. The relative humidity in the intake air determines the
quantity of condensation.

Possible Malfunctions:

• Insufficient compressor lubrication.

• Insufficient air/oil separation and high differential pressure in the purifier cartridge.

• Corrosion and rust formation due to condensation in the oil.

Drain the condensation regularly when the compressor unit is cold prior to startup.

Maintenance Procedure:

1. Switch off the main power to the unit.

2. Slowly unscrew the oil fill cap.

3. Unscrew the oil drain plug carefully and place a container underneath.

4. Drain the condensation from the separator receiver until oil starts to come out. Then replace the drain
plug.

5. Fill separator receiver with oil up to maximum, then close oil fill.

6. Switch on compressor and run for 3 minutes.

7. Check oil level and fill if necessary.

8. Dispose of condensation in accordance with local and federal regulations.
