2. After the loading mixer truck starts the engine, the mixing drum should be rotated at low speed for about 10 minutes, so that the hydraulic oil temperature can rise above 20 ° C before it can work.

3.将自上料搅拌车停放在户外时，应在装载前将搅拌筒倒转以排出水和碎屑，以确保混凝土的质量。

3. When the self-loading mixer is parked outdoors, the mixing drum shall be inverted before loading to discharge water and debris to ensure the quality of concrete.

4.在自上料搅拌运输车运输混凝土时，请确保牢固放置滑动铲斗，以防止其由于松动而摆动，伤害行人或影响其他车辆的正常运行。

4. When transporting concrete by self-loading mixer truck, please ensure that the sliding bucket is firmly placed to prevent it from swinging due to looseness, hurting pedestrians or affecting the normal operation of other vehicles.

5.自上料搅拌运输车装载和运输混合混凝土时，搅拌桶的速度为2-10 rpm。 在运输过程中，在平坡上行驶时，搅拌桶的速度保证为2-3 rpm。 当路面大于50，或左右晃动较大的路面时，应停止搅拌旋转，并在路况改善后恢复搅拌旋转。

5. When loading and transporting mixed concrete by self-loading mixer truck, the speed of mixing drum is 2-10 rpm. During transportation, when driving on a flat slope, the speed of the mixing drum shall be 2-3 rpm. When the road surface is more than 50, or the road surface shakes greatly from left to right, the mixing and rotation shall be stopped, and the mixing and rotation shall be resumed after the road condition is improved.

6.自上料搅拌车运输混凝土的时间不能超过搅拌站指定的时间。 在运输混凝土的过程中，不得长时间停止搅拌桶，以防止混凝土偏析。 驾驶员应始终观察具体情况，如有异常请向调度室报告，并提出处理要求。

6. The time for transporting concrete from the loading mixer truck shall not exceed the time specified by the mixing station. During the transportation of concrete, the mixing drum shall not be stopped for a long time to prevent concrete segregation. The driver should always observe the specific situation. If there is any abnormality, please report to the dispatching room and put forward the handling requirements.

7.小型混凝土搅拌车装载混凝土时，现场停滞时间不得超过1小时。 如果时间到了，应该要求现场负责人及时处理。

7. When the small concrete mixer truck is loading concrete, the dead time on site shall not exceed 1 hour. If the time is up, the person in charge of the site should be required to deal with it in time.

8.小型混凝土搅拌车运输的混凝土坍落度不得小于8厘米。 从混凝土进入储罐到卸料，在高温下，卸料时间不得超过2小时；在雨天中，当混凝土温度较低时，卸料时间不得超过2.5小时。

8. The slump of concrete transported by small concrete mixer truck shall not be less than 8 cm. From concrete entering the storage tank to unloading, the unloading time shall not exceed 2 hours under high temperature; In rainy days, when the concrete temperature is low, the unloading time shall not exceed 2.5 hours.

9.在排出混凝土之前，自动进料搅拌机应在排出前以10-12 rpm的速度旋转搅拌筒1分钟。

9. Before discharging concrete, the automatic feed mixer shall rotate the mixing drum at a speed of 10-12 rpm for 1 minute before discharging.

10.自上料搅拌运输车完成卸料后，立即使用随车提供的软管冲洗进水口，卸料斗和卸料槽，以粘在车身上的污垢和残留的混凝土，然后倒入150-200L 干净的水倒入搅拌桶中。 在返回途中，应缓慢旋转搅拌桶以清洁内壁，并避免残留的炉渣附着在搅拌桶壁和搅拌叶片上。

10. After the unloading of the loading mixer truck, immediately use the hose provided with the truck to wash the water inlet, the unloading hopper and the unloading trough to remove the dirt and residual concrete stuck on the car body, and then pour 150-200L clean water into the mixing bucket. On the way back, the mixing drum shall be slowly rotated to clean the inner wall and avoid residual slag adhering to the mixing drum wall and mixing blades.

11.自上料搅拌运输车完成工作后，应清洁搅拌桶的内部和主体，并且不得将剩余的混凝土留在桶中。

11. After the completion of the work of the loading mixing truck, the inside and main body of the mixing bucket shall be cleaned, and the remaining concrete shall not be left in the bucket.

12.泵工作时，禁止自上料搅拌运输车空转，连续使用时间不得超过15分钟。

12. When the pump is working, it is forbidden to idle the self-feeding mixing truck, and the continuous use time shall not exceed 15 minutes.

13.自上料搅拌运输车的水箱中的水量应始终保持充满状态，以备不时之需。 冬季关闭后，应将水箱，水泵，水管和搅拌桶中的水排干，并停放在阳光充足的地方，不要积水，以免冻结机器。

13. The water in the water tank of the self-feeding mixing truck should always be kept full in case of emergency. After shutdown in winter, the water in the water tank, water pump, water pipe and mixing bucket should be drained and stored in a place with sufficient sunshine. Do not accumulate water to avoid freezing the machine.
