When it shuts down, press DISPLAY SELECT button once and use the up down arrows to see the code just before shutdown.

HIGH AIREND TEMP

HIGH AIR PRESSURE

LOW SUMP PRESSURE

PRESSURE OR TEMP SENSOR FAIL

CHECK MOTOR ROTATION

MOTOR OVERLOAD

FAN MOTOR OVERLOAD

STARTER FAULT

I am assuming this has a Intellisys controller.

most have safety shut downs built in, on the compressor side you will have a high discharge temp shut down, usually set to shut down @ 230 degrees F. normal temp should be @ 180F if it is running hot first check oil level on the compressor, and that the radiator is clean. some machines will have a thermostat that will only allow oil flow to go to the radiator after it comes up to about 150 degrees F. you really need to have a manual on the machine to see what other safety's it may have on the compressor and engine side as well.

Testimonial: "Thank you very much for responding. It was a little low on coolant. The comp. oil level was fine. I changed the fuel filter and the prob is gone"

More than likely it is a problem with the inlet control, commonly I have found wear in the throttle linkage can cause this or a faulty sump pressure sensor that is out of calibration.

I have a ingersoll compreesor that keeps shuting down on high discharg air temp
