1. Correctly grasp the service cycle of the gearbox oil of concrete mixer and replace it regularly. In general, most manufacturers recommend that the oil change period of the transmission is generally 2 years or 40000-60000 km. When using the car owner's friend to keep the transmission oil clean, because the transmission oil will produce oil dirt after a long period of use, may form sludge, will increase the friction and wear parts, will also make the body movement of the valve body, hydraulic control, make the automatic hybrid vehicle transmission abnormal.

2.经常检查变速器油位是否正常。检查传动油需要预热50℃左右,然后把杆在每一站停车后2秒,目前正常的油位应位于高和低之间的线,如果没有达到,应及时添加相同的油质量。

2. Check the transmission oil level regularly. To check the transmission oil, preheat it to about 50 ℃, and then stop the rod at each station for 2 seconds. The current normal oil level should be between high and low. If not, add the same oil quality in time.

3.正确更换变速箱油。动态换油目前更提倡换油的方法,选择特殊的齿轮箱清洗设备,在传播的过程中工作,旧的油将完整的循环,排出干净然后参与新变速器油,这样换油率高达90,以确保的换油。

3. Change the transmission oil correctly. At present, the dynamic oil change method is more advocated. Special gear box cleaning equipment is selected to work in the process of transmission. The old oil will be completely recycled and discharged, and then participate in the new transmission oil. In this way, the oil change rate can reach 90, so as to ensure efficient oil change.
