What to do if the motor pump unit doesn't stop at maximum pressure in my California Air Tools 20040DC?
- KKellie WalkerAug 15, 2025
If the motor pump unit of your California Air Tools Air Compressor doesn't stop when the tank pressure reaches its maximum working pressure (8 bar or 116 PSI), and the safety valve vents air, immediately stop the compressor and contact Customer Support, as this indicates that the pressure switch is defective or needs adjusting.
