  • Cause of failure: 

    1. Motor is overheated due to overloaded use of the machine, such as continuous climbing, overloading, etc..The machine has entered self-protection mode, and work intensity needs to be reduced.

    2. Motor is overheated because drive wheel or brake is stuck by interference materials.

    3. If the above causes are ruled out, most likely controller is faulty

    Checking method: Keep the machine off for 15 minutes, turn it on and see if Err25 appears
