Xas 185 jd7 shuts down

Sounds like everything works perfectly, except for the shutting down part. It could be a safety switch that opens and shuts down the machine - maybe the compressor is overheating (screw element outlet temperature)? Although most of the time, that only happens when running loaded. Any indication? Alarm light, etc? It could also be a loose electrical connection. Does it shut down always, and around the same time? Or does the problem come and go and happen at different times? Hope this helps :) Ask more if needed :) Thanks, Cas
