The second-hand Sany 75-9 excavator, the second-hand Sany 75-9 Sany 75 excavator price Sany machine, we all know that after the first maintenance, every 250 hours, there is no problem except the normal maintenance. I am very satisfied with this, which has changed my view on domestic machines, I used to think that the domestic engine couldn't work normally for two days. Now the fuel consumption of the machine is under the condition of turning on the air conditioner. If the air conditioner is not turned on, it will be less than 30. I have been working with six gas pedals. Several friends said that five gas pedals are enough. But I think the engine feels very loaded when it is 5 throttle, and the engine noise is very hard to hear, so I always work with 6 gas pedals. Every day, I put water in three places, oil-water separator and bottom of oil tank, and I beat butter twice, once at noon; I hit it again after work in the afternoon, but only at noon at the joint of big and small arms. At ordinary times, only the parts related to the bucket and the joint of the forearm and forearm are played. In other places, it is basically played once every 30-50 hours, and the rotation is played once every 50 hours. Now I feel good, I'll talk about the advantages and disadvantages. Advantages: the whole machine has strong power and fast speed, especially the digging force and walking force. Under the condition of competing with the rotating speed on the same platform, the majority of foreign investment is not inferior. Now, a few foreign-funded machines with 4 headlights are quite good at night.
