1. start the motor and engine, and there is no sound, which means there is no power on. It is recommended to check whether the battery pile head is in poor contact or burnt out. If you first confirm that the hydraulic master switch is locked, because there are many models, it is impossible to start when the hydraulic master switch is not turned on. The very humanized design will make some people who are just beginning to contact unable to adapt for a time.
2. start the motor and the engine, but the speed is slow and the sound is weak, indicating that the battery power is insufficient. It is recommended to check whether the generator belt is normal. It is best to measure the power generation. If it is normal, you can only call the excavator owner. The owner needs to pay for the excavator to repair and replace the battery.
3. start the motor. The speed and sound are normal, but the engine just can't be started, indicating that the oil hasn't arrived. It is recommended that you clean up whether the diesel pipeline is blocked. The two points that are easy to be blocked are the small filter screen at the bottom of the diesel tank and the hand pump. It is also possible that the air can be removed when the filter element is replaced by screwing the exhaust screw and pumping oil with the hand pump.
It is worth mentioning that many small excavators use a certain engine of Yangma, which cancels the hand oil pump and adds a small electronic oil pump at the oil pipe entering the diesel filter element, so we will hear the clicking sound at the engine after turning on the power. Repairing this small electronic pump by excavator is a completely different concept from the high-pressure electronic oil pump of EFI, This small electronic pump is only used to increase the flow of diesel oil in the oil pipe. However, once there is a problem with this pump, the engine will not start, or it will shut down immediately after starting.
