The driving device of the automatic concrete mixer is also a very important part in the actual operation of the equipment. Therefore, it is necessary to check the quality of the oil to a certain extent, but how should we operate it?

1.将混凝土自动搅拌车放在平坦的表面上，并拧紧手刹。

1. Place the automatic concrete mixer on a flat surface and tighten the handbrake.

2.使发动机空转几分钟。

2. Idle the engine for a few minutes.

3.踩下制动踏板，将操纵杆换倒档，前进档等，并在每个档中停留几秒钟，以向液压变矩器和所有换档执行器注满液压油。，将操纵杆移停车位置。

3. Press the brake pedal, shift the control lever to reverse, forward, etc., and stay in each gear for a few seconds to fill the hydraulic torque converter and all shift actuators with hydraulic oil. Finally, move the lever to the park position.

4.将自动变速箱油位计从加油管中拉出，将所有清洁的油位计插入加油管，然后拉出以检查油位计的油位。

4. Pull out the automatic transmission oil level gauge from the oil filling pipe, insert all clean oil level gauges into the oil filling pipe, and then pull out to check the oil level of the oil level gauge.

在检查或诊断混凝土自动搅拌车的传动装置之前，必须检查传动装置的油位和质量。在档位选择器处于位置P且发动机空转少几分钟的情况下，机油将达到正常工作温度。差速器和变速箱是正常稳定的。

Before checking or diagnosing the transmission of automatic concrete mixer, the oil level and quality of the transmission must be checked first. With the gear selector in position P and the engine idling for at least a few minutes, the oil will reach normal operating temperature. The differential and transmission are normally stable.
