WARNING
When the compressor is engaged and operating, there are two safety
shutdown circuits that will shut down the engine: fourth stage head
temperature and low compressor oil pressure. Ensure, when
compressor unit is operating, that the safety bypass is OFF. Severe
damage to equipment or injury to personnel may result.
