The flexible and correct operation methods of automatic feeding mixer can be summarized as follows: one light, two stability, three separation, four diligence, five coordination and six prohibition.

一轻：在自动上料搅拌车作业时脚跟紧抵驾驶室地板，脚板和油门踏板保持平行，轻缓地下压加油踏板。

First light: during the operation of the automatic feeding mixer, the heel is tightly against the cab floor, the foot plate is parallel to the accelerator pedal, and gently press the refueling pedal.

二稳：自动上料搅拌车在作业中，油门始终要稳住。一般作业状态下，油门开度在70左右为宜。

Second stability: the accelerator of the automatic feeding mixer shall always be stable during operation. Under normal operating conditions, the throttle opening should be about 70.

三离：在自动上料搅拌车作业时，脚板应和制动踏板分离开，平放到驾驶室地板上，决不能踩在制动踏板上。自动上料搅拌车常常在凹凸不平的工地作业，如果脚总是踩在制动踏板上，机身上下窜动会造成驾驶员不轻意地踩制动踏板。一般情况下，要用控制油门减速的办法控制机况和换挡。这样既避免了频繁制动造成制动系统过热，又为自动上料搅拌车快捷的提速带来方便。

Three separation: during the operation of automatic feeding mixer, the foot plate shall be separated from the brake pedal and placed flat on the cab floor, and must not step on the brake pedal. The automatic loading mixer truck often works on uneven construction sites. If the foot always steps on the brake pedal, the body will move up and down, which will cause the driver to step on the brake pedal carelessly. Generally, it is necessary to control the engine condition and gear shift by controlling the throttle deceleration. This not only avoids the overheating of the braking system caused by frequent braking, but also brings convenience to the fast speed-up of the automatic feeding mixer.

四勤：在自动上料搅拌车作业时，特别是在铲挖作业时，应在油门稳定情况下，用循环扳动起升和转斗操纵杆的方法使铲斗铲满物料。起升和转斗操纵杠的循环扳动就是所说的“勤”。这个过程非常重要，对耗油量的影响很大。

Four times: during the operation of automatic loading mixer truck, especially in the digging operation, the bucket shall be filled with materials by turning the lifting and rotating bucket control lever in a circular manner under the condition of stable throttle. The cyclic pulling of the lifting and turning bucket control lever is the so-called "diligence". This process is very important and has a great impact on fuel consumption.

五协调：协调就是起升和转斗操纵杠的配合。自动上料搅拌车一般的铲挖过程是将铲斗平放在地面，平稳地驶向料堆。在铲斗平行铲往料堆遇阻力时，应遵循先起臂后收斗的原则。这样可以避免铲斗底部受到阻力，从而能够充分发挥大的掘起力。

V. coordination: coordination is the cooperation between lifting and rotary bucket control lever. The general digging process of automatic loading mixer truck is to put the bucket flat on the ground and drive smoothly to the material pile. When the bucket shovels parallel to the material pile and encounters resistance, the principle of lifting the arm first and then retracting the bucket shall be followed. This can avoid the resistance at the bottom of the bucket, so as to give full play to the large digging force.

六严禁：是严禁轮胎打滑。自动上料搅拌车作业时，遇阻力而猛加油门往往会出现轮胎打滑的现象。这种现象通常是由于驾驶员操作不当造成的，既增加了油耗又损伤了轮胎。其次是严禁后轮翘起。由于自动上料搅拌车的掘起力大，驾驶员通常在铲挖坚实的原土和石料山等作业过程中，如果操作不当就容易出现两后轮翘起离地现象。这种翘起动作的落地惯性，会造成铲斗的刃板断裂、铲斗变形；后轮翘起很高时还容易引起前后机架等结构的焊接处开裂，甚板材断裂等。第三是严禁撞击料堆。铲挖普通物料，自动上料搅拌车可以用II档作业，严禁以II档以上的档位向料堆进行惯性冲击。正确的方法应该是铲斗在接近料堆时适时地把档位转换为I档完成一个铲料过程。

Six: first of all, it is forbidden to slip the tires. During the operation of automatic loading mixer truck, the fuel filler door is often subject to tire slip in case of resistance. This phenomenon is usually caused by improper operation of the driver, which increases fuel consumption and damages the tire. Secondly, it is strictly prohibited to tilt the rear wheel. Due to the large digging force of the automatic loading mixer, the driver is usually prone to the phenomenon that the two rear wheels are tilted off the ground if the driver does not operate properly in the process of digging solid original soil and stone hill. The landing inertia of this tilting action will cause the blade of the bucket to break and the bucket to deform; When the rear wheel is tilted up very high, it is also easy to cause cracking at the welding joints of front and rear frames and other structures, and even plate fracture. Third, it is strictly prohibited to hit the pile. When excavating ordinary materials, the automatic feeding mixer can operate with gear II. Inertial impact on the material pile at a gear above gear II is strictly prohibited. The correct method should be to timely change the gear to gear I when the bucket approaches the material pile to complete a shoveling process.
