In this case, we can check the cause of the problem. In fact, the idea is very simple. The temporary engine can't start, regardless of the reasons. One is that there is no electricity and the other is no oil
If you drive Komatsu pc56 or Kobe Steel sk75, it is recommended that you first confirm that the main hydraulic switch is turned off, because there are many models, when the hydraulic main switch is not turned on, it can not activate the very user-friendly design, but it will make some people not adapt to the contact
2. The starting motor is moving, but the speed is slow, the sound is weak, and the power is insufficient. It is suggested that the battery power is insufficient. It is suggested to check whether the generator belt is normal. Measure the power generation. If it is normal, you can only play normally. Call the boss of the small excavator and tell him two news, one bad news and one good news. The bad news is that the boss needs to pay for a new battery, You can save a cent on old batteries
3. Start the motor, the speed is normal, the sound is normal, but the engine can not start, indicating that there is no oil. It is suggested that you clean the diesel pipe to see if it is blocked. The two points that are easy to block are the bottom of the diesel tank and the manual pump. Small filter. It may be that when replacing the filter, insert air, loosen the exhaust screw, and pump oil with hand pump to exhaust the air, Yanma company uses many small excavators. In one engine, the manual oil pump is canceled, and a small electronic oil pump is added to the oil pipe entering the diesel filter. So when we turn on the power, we can hear the sound of the engine, The electronic pump is a completely different concept. The small electronic pump has the function of increasing the diesel flow in the tubing. However, if there is a problem with the pump, the engine will not start or shut down immediately after starting.
