Solution to generator set automatic shutdown failure:
1. Check the fuel injection pump drive shaft connection bolt for looseness and tighten it if necessary.
2. Check whether the connection of each oil pipe joint is reliable. If there is a leak, repair it.
3. Loosen the filter or quality oil pump bleed plug and pump the oil with a hand pump. If oil is leaking, this indicates that the problem lies in the high pressure oil line; flows, this indicates that the fault is in the high pressure oil circuit. The fault is in the low pressure oil line.
4. The problem lies in the low pressure oil line, mainly due to blocked diesel filter. The diesel filter needs to be cleaned or the filter element needs to be replaced.
5. If the engine speed is high or low before stalling, this indicates that there is water in thediesel, and the water should be disposed of or the diesel should be replaced in time.
