Many small excavator drivers often encounter a problem that the small excavator cannot start. If it is often unable to start, especially in winter, then congratulations, you may have a small summer vacation, because this is also caused by the situation of the car engine itself, it may be due to cylinder leakage or a large gap in the engine piston, The resulting insufficient shrinkage temperature, or other reasons, in short, cannot be solved by small excavator drivers. And in such a situation, it is not recommended to use the car engine to run the sprayer. Although this thing works very well, it will make the car engine addictive like meth.
If it is temporarily unable to start, for example, it was fine yesterday, but it started today, or it just stopped, you can find out the reason for this problem, in fact, the concept is very simple , This kind of temporary engine failure is only caused by two factors, first, the power is not connected, and second, the oil is not available. Inventory reasons should take into account these multiple levels:
1. If there is no sound from the starter, it means that it is not plugged in. It is recommended to check whether the battery pile cap is in poor contact or burnt out. If you are driving a model such as Doosan PC56 or Kobelco SK75, it is recommended that you first make sure that the main brake of the hydraulic machine is pushed and locked, because there are many models that cannot be started when the main brake of the hydraulic machine is not opened, which is very The personalized design will make some people who are in contact with it at the beginning unable to adapt for a while.
2. The engine starts to move, but the speed is relatively slow, and the sound is sluggish, indicating that the battery power is not enough. It is recommended to check whether the generator belt is normal. It is best to test the power generation capacity. If everything is normal, the general condition Next, you can only call the boss of the small excavator and tell him two pieces of information, one bad news and one good news. The bad news is that the boss has to pay for a new battery. can save some money.
3. Start the engine, the speed ratio is normal, and the sound is normal, but the engine is not running, indicating that the oil has not arrived. It is recommended that you clean the diesel pipeline and see if it is blocked. The two points that are easy to be blocked are , a small filter screen at the bottom box of the diesel engine and at the hand gasoline pump. It may also be that gas has entered when changing the filter element, loosen the exhaust pipe screw, and use the gasoline pump oil valve to remove the gas. It is worth mentioning that many small excavators use a Yanmar car engine, cancel the hand gasoline pump, and add a small electronic oil pump to the oil pipeline entering the diesel filter, so we turn on the power of the main engine Afterwards, you will hear the creaking sound of the engine. This small electronic pump and the high-pressure electronic oil pump of the EFI are two completely different concepts. It is just a function of the flow rate, but once there is a problem with this pump, it will also cause the engine to fail to start, or the engine will stop shortly after running.
Drivers of small excavators sometimes encounter exactly the same problem, that is, they cannot turn off the fire, and even if the key is pulled out, they will not turn off the fire. This situation is usually caused by the failure of the fire-off suspension wire to open the hood by itself. , Push the end of the hanging wire in time, and the fire can be turned off, and the situation of stopping the fire and hanging the wire will also cause failure to start.
