1. Overtemperature maintenance is invalid, and the overload protector has been removed and replaced.
2. The braking system is stuck, and the manual transmission chain drives it to rotate twice.
3, continuous operation time is too long, thermal maintenance is broken. The motor temperature can be reduced
4. The bridge rectifier is broken or the magnet coil is broken, and the braking system is stuck. Remove and replace the bridge rectifier or magnet coil.
5. The normally closed contact of the travel switch is blocked, and the contact point is polished or the travel switch is disassembled and replaced.
