1. Start the motor and engine, there is no sound, indicating that there is no power. It is recommended to check whether the battery pile head is in poor contact or burned out. If you have first confirmed that the hydraulic main switch is locked, because there are many models, the hydraulic When the main switch is not turned on, there is no way to start it. It is a very user-friendly design but will make some people who are new to it unable to adapt for a while.
2. Start the motor and the engine started, but the speed is slow and the sound is weak, indicating that the battery power is insufficient. It is recommended to check whether the motor belt is normal. It is best to measure the amount of power generation. If they are normal, under normal circumstances, you Can only call the excavator boss, the boss needs to pay for the excavator repair and replace the battery.
3. Start the motor, the speed is normal, the sound is normal, but the engine can not start, indicating that the oil has not arrived, it is recommended that you clean up the diesel pipeline is blocked, the two points that are easily blocked are the small position at the bottom of the diesel tank and the hand oil pump It is also possible that the filter screen is filled with air when the filter element is changed, and the air screw is screwed and the oil is pumped by the hand oil pump to remove the air.
It is worth mentioning that many small excavators use a Yanmar engine. The hand oil pump is eliminated, and a small electronic oil pump is added to the fuel pipe entering the diesel filter, so we will hear after turning on the power. The sound of the engine, the excavator repairs this small electronic pump and the high-pressure electronic oil pump of the electronic injection machine are two completely different concepts. This small electronic pump plays the role of increasing the flow of diesel in the tubing, but this If there is a problem with the pump, it will also cause the engine to fail to start, or to shut down immediately after starting.
