1、新机使用前应按照混凝土搅拌机使用说明书的要求，对各系统和部件逐项进行检验及必要的试运转。空车运转，检查搅拌筒或搅拌叶的转动方向，各工作装置的操作、制动，确认正常，方可作业。

1. Before using the new machine, all systems and components shall be inspected item by item and necessary test run shall be carried out according to the requirements of the operation manual of the concrete mixer. When the truck is running empty, check the rotation direction of the mixing drum or mixing blade, and the operation and braking of each working device. The operation can be carried out only after it is confirmed to be normal.

2、混凝土搅拌机应安装在牢固的台座上。当长期使用时，应埋置地脚螺栓；如短期使用，可在机座下铺设枕木并找平放稳。

2. The concrete mixer shall be installed on a firm pedestal. In case of long-term use, anchor bolts should be embedded; For short-term use, sleepers can be paved under the base and leveled and placed stably.

3、对于移动式混凝土搅拌机，应安装在平坦坚硬的地坪上用方木或撑架架牢，并保持水平面轮胎不受力。如果使用时间超过三个月以上时，应将轮胎卸下妥善保管轮轴端部应做好清洁防锈工作。

3. For mobile concrete mixers, they should be installed on a flat and hard floor, firmly supported by square timber or brackets, and keep the horizontal tires free from stress. If it is used for more than three months, the tire should be removed and kept properly, and the end of the axle should be cleaned and rustproof.

4、对某些需要挖设上料斗地坑的搅拌机，其坑口周围应垫高夯实，以防地面水流入坑内。上料轨道架的底端支承面应夯实或铺砖、架的后面亦须用木料加以支承，防止工作时轨道变形。

4. For some mixers that need to dig a hopper pit, the pit mouth should be padded and compacted to prevent the ground from flowing into the pit. The bottom bearing surface of the loading track frame shall be compacted or paved with bricks, and the back of the frame shall also be supported with wood to prevent track deformation during work.

5、混凝土搅拌机启动后，应使搅拌筒达到正常转速后进行上料，上料后要及时加水；添加新料必须先将搅拌机内原有的混凝土全部卸出后才能进行。不得中途停机或满载荷时起动搅拌机，反转出料者除外。

5. After the concrete mixer is started, the mixing drum should be loaded after reaching the normal speed, and water should be added in time after loading; Adding new materials can only be carried out after all the original concrete in the mixer is unloaded. Do not stop halfway or start the mixer when it is fully loaded, except for reverse discharging.

6、在混凝土搅拌机使用中，切勿使砂石落入机器运转部分中去，以免使运转部件卡住损坏。上料斗提升后，斗下不能有人通过或停留，以免制动器失灵发生意外事故。如必在斗下检修或进行清理工作时，强行停机并将上料斗用保险链条拉牢。

6. During the use of the concrete mixer, do not let the sand fall into the running part of the machine, so as to prevent the running parts from being stuck and damaged. After the upper hopper is lifted, no one can pass or stay under the hopper to avoid accidents due to brake failure. If it is necessary to overhaul or clean under the bucket, forcibly stop the machine and fasten the upper hopper with a safety chain.

7、搅拌机作业中，如发现故障不能继续运转时，应立即切断电源，将搅拌筒内的混凝土干净，然后进行检修。

7. During the operation of the mixer, if it is found that the mixer cannot continue to operate due to faults, the power supply should be cut off immediately, and the concrete in the mixing drum should be cleaned before maintenance.

8、作业后，应对搅拌机进行清洗，操作人员如需要进入筒内清洗时，必须切断电源，设专人在外监护，或卸去熔断器并锁好电闸箱，然后方可进入。

8. After operation, the mixer shall be thoroughly cleaned. If the operator needs to enter the drum for cleaning, he must cut off the power supply, assign a special person to supervise outside, or remove the fuse and lock the switch box before entering.

9、搅拌机上料斗的摇把，应用销子固定，以免人进入简内清理时，身体碰触摇把使料斗提升，发生挤压事故。

9. The handle of the hopper on the mixer shall be fixed with a pin to prevent people from touching the handle to lift the hopper and causing extrusion accidents when entering the chamber for cleaning.

10、作业后，应将搅拌机料斗降落到料斗坑，如需升起则应用链条扣牢。

10. After operation, the mixer hopper should be lowered to the hopper pit, and if it needs to be lifted, it should be fastened with a chain.
