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.

二穩：自動上料攪拌車在作業中，油門始終要穩住。一般作業狀態下，油門開度在70%左右為宜。

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%.

三離：在自動上料攪拌車作業時，腳板應和制動踏板分離開，平放到駕駛室地板上，決不能踩在制動踏板上。自動上料攪拌車常常在凹凸不平的工地作業，如果腳總是踩在制動踏板上，機身上下竄動會造成駕駛員不輕意地踩制動踏板。一般情況下，要用控制油門減速的辦法控制機況和換擋。這樣既避免了頻繁制動造成制動系統過熱，又為自動上料攪拌車快捷的提速帶來方便。

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：在自動上料攪拌車作業時，特別是在鏟挖作業時，應在油門穩定情況下，用循環扳動起升和轉斗操縱桿的方法使鏟斗鏟滿物料。起升和轉斗操縱杠的循環扳動就是所說的“勤”。這個過程非常重要，對耗油量的影響很大。

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.

五協調：協調就是起升和轉斗操縱杠有機的配合。自動上料攪拌車一般的鏟挖過程首先是將鏟斗平放在地面，平穩地駛向料堆。在鏟斗平行鏟往料堆遇阻力時，首先應遵循先起臂后收斗的原則。這樣可以有效地避免鏟斗底部受到阻力，從而能夠充分發揮最大的掘起力。A

V. coordination: coordination is the organic 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 effectively avoid the resistance at the bottom of the bucket, so as to give full play to the maximum digging force. A
