It should turn around smoothly, without any 'hickups' (be sure to completely shut down the air compressor!). Check the isolation of the motor windings. Should be in the mage-ohms (you need an isolation tester / high voltage ohm meter for this). Check the voltage when the compressor is running.
[pdf] Lishui Fucai Electromechanical Equipment Co., Ltd. has been deeply engaged in industrial products such as screw air compressors, air coolers, factory cooling and ventilation equipment for more than ten years.
[pdf] Therefore, users need to clean and maintain the oil shutoff valve regularly, optimize the compressor operating environment, use it in an environment with good ventilation and heat dissipation, away from volatile gases, debris and floating debris, etc., and replace the air filter in strict accordance with the pressure difference parameter requirements. .
