Your Boss compressor has safety switches that protect the engine and compressor from permanent damage. The safety switches are as follows:
1.Engine Oil Pressure: This is a normally open switch that closes with 15 PSI of engine oil pressure.
2.Engine Coolant Temperature: This is a normally closed that opens a 220° F.
3.Compressor Oil Temperature: This is a normally closed switch that opens at 245°F.
All above switches are in series with the power feed to the engine fuel solenoid. If any of the switches open, power to the solenoid is lost and the engine shuts down.
WARNING
OPERATING WITHOUT SAFETY SWITCHES COULD CAUSE SEVERE PERSONAL INJURY OR DEATH AND CAUSE SIGNIFICANT PROPERTY DAMAGE. IT WILL VOID EXISTING WARRANTIES. ALWAYS ENSURE THAT ALL SAFETY SYSTEMS ARE FUNCTIONAL.
