General Operation Notes
Before Start-Up
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. 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 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.
If adjustment is necessary for cable operated speed controls, loosen the jam nut on the
cable end, make the adjustment and retighten the jam nut.
For electronic operated speed controls, adjust speed adjustment screw as needed to set
RPM.
For setting engine RPM through the chassis ECM, contact local chassis dealer.
When the air pressure falls below 120 PSI, the 12 volt electric solenoid opens allowing
hydraulic oil to flow to the hydraulic drive motor then back to the manifold and through
the oil cooler assembly. Once the air pressure reaches 150 PSI the solenoid closes
shutting off the oil flow to the motor and diverts the oil to the oil cooler.
With the compressor engaged, the main cooling system, which consists of an oil cooler,
electric fan motor and fan continually runs drawing ambient air through the cooler fins
and across the fan assembly discharging heated air past the compressor and out the
cover assembly.
SHD-60 Operation Notes
To use the compressor, start the engine and engage the hydraulic system with the
compressor toggle switch. Through the hydraulic valve manifold, the system will now
function automatically. Once engaged, adjust the engine speed control to ensure that the
compressor speed does not exceed 1300 RPM under load.
