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 Oil”). 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. 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 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.
