Normal use resumes after restarting
Checking method:
1. The truck entered into sleep mode after long time no use
2. Touching emergency reverse switch caused a temporary stop of the truck. It works normally after restarting. This is not a quality issue.
3. If the above causes are ruled out, most likely brake is stuck
Temporarily release the brake and see if problem is solved (This is to check if brake is stuck)
Checking method: temporarily remove the brake (Note: truck shall not be used without brake).
Measure the main line current of the power supply with a clamp ammeter, and compare the current before and after brake is removed
Tools: allen wrench; clamp ammeter
