.Insufficient power generation by the motor
. The ground wire connected to the engine is not in good contact
Insufficient cold start oil
.There is a problem with the oil pump or injector, and it needs to be calibrated
The engine's low-pressure oil circuit is faulty, making it difficult for the excavator to start.
. The valve assembly in the deep well pump is not tightly closed.
.Electrical system failure.
. The battery is low.

2Excavate excavator is difficult to start when it is working in winter. In addition to the above reasons, it may be caused by the waxing of the diesel used by the excavator. The maintenance excavator has the strength to undertake "difficulty problems" that cannot be repaired elsewhere. It has the leading domestic excavator testing, debugging and maintenance equipment and can accurately detect the actual problems of your machine. Common failures of excavators such as excavator weakness, hoisting, slow movement, walking deviation, burning oil, etc. can be completed in a short time, saving maintenance waiting time for the owner.
Difficult to start maintenance of excavate machine:
1If the excavator is difficult to start when it is in use, first check whether the battery power of the excavator is sufficient? Is the hydraulic oil used waxed? And is the oil circuit blocked? ?

4 Then inspect the excavator's deep well pump, injectors, etc.
In addition, if it is difficult to start the excavate machine in winter, you can do the following to prevent it:
1 Use starter fluid for excavate machine (recommended use of starter fluid)
2 grilled oil tank, grilled oil pan.
3 Cover the engine with a quilt or blanket when warming the car in winter, and increase the starting speed by reducing heat loss and increasing the speed of the hot car.
