Micro DC motors sometimes fail to turn on in the process of use, so what are the causes of DC motors failing to turn on? The following is to introduce you to
1. The lock is not pulled out
2. The pipe supplying oil to the main distribution valve is clogged, or the DC motor supply valve is closed.
3. The switching valve is not in the correct position, either in the automatic position or in the manual position.

4. The connecting valve switching valve of the relay is not closed
5. The handle pin of the opening limiter is loose.
6. The emergency stop solenoid valve action is not restored to its original position
