1. The capacity, quality and slump of concrete transported by cement mixer truck should meet the concrete industry standards and requirements.

2、大型拌和罐车在混凝土运送过程中罐体制止停转，避免形成混凝土的凝聚，停转重启时会形成对液压体系、减速机的冲击，导致液压泵和马达的损坏。

2. In the process of concrete transportation, the tank body of large mixing tank truck should be stopped to avoid the formation of concrete condensation. The impact on the hydraulic system and reducer will be formed when stopping and restarting, which will lead to the damage of hydraulic pump and motor.

3、小型搅拌车在公路上行进时，加长溜槽有必要放置在卸料溜槽支架上并用挂钩挂牢，不允许挂在主排料溜槽上工作；主排料溜槽要旋转到固定位置，拉下定位手柄，用锁紧手柄将弹簧变幅组织锁止，避免由于不固定而摇晃，形成伤人事端和影响其它车辆工作可能。

3. When the small mixer truck is moving on the road, it is necessary to place the lengthened chute on the support of the discharge chute and hang it firmly with the hook. It is not allowed to hang it on the main discharge chute. The main discharge chute should be rotated to a fixed position, pull down the positioning handle, and lock the spring luffing organization with the locking handle, so as to avoid shaking due to unfixed, causing injury and affecting the work of other vehicles 。

4、作业设备接连工作时刻不该超越8h。

4. The continuous working time of operation equipment should not exceed 8h.

5、卸料时，如发现水分蒸腾，塌落度偏低不能满意用户要求时，可适当向筒内加水，然后以10—14r/min的速度旋转30转后卸料，使混凝土充沛拌和。

5. When discharging, if it is found that water transpiration and low slump can not meet the user's requirements, water can be properly added into the cylinder, and then the material can be unloaded after 30 rotations at the speed of 10-14 R / min, so that the concrete can be fully mixed.

6、搅拌车在空载工作过程中，拌和筒不得停转避免波动时形成滚道和托轮部分磕碰，导致托轮和滚道的反常损坏。

6. In the process of no-load operation of the mixer truck, the mixing drum shall not stop, so as to avoid the collision between the roller track and the supporting roller, which may cause abnormal damage to the roller and raceway.

7、水箱的水量要常常加满，以备急用。水箱加水前，有必要翻开放气阀把箱内空气放掉；冲刷时翻开气阀，冲刷结束或者停用时应将水罐内气体放掉。冬天停放时，水箱和供水体系里，不得有剩下水，避免冻裂。注意： 水箱仅在供水时加压,不要带着加压水箱在公路上行进。

7. Always fill up the water tank in case of emergency. Before adding water into the water tank, it is necessary to open the air valve to let off the air in the tank; when flushing, turn on the air valve, and when the flushing is finished or stopped, the gas in the water tank should be discharged. When parking in winter, there should be no residual water in the water tank and water supply system to avoid frost cracking. Note: the water tank is only pressurized when supplying water. Do not carry the pressurized water tank on the road.

8、混凝土搅拌罐车在满载混凝土正转，如要回转，有必要操作手柄使正转停稳后，再操作手柄回转。禁止正转过程中操作手柄使其回转。搅拌车

8. When the concrete mixing tank truck is fully loaded with concrete, it is necessary to operate the handle to stop the forward rotation, and then operate the handle to rotate. Do not operate the handle to make it rotate during forward rotation. Price of mixer truck
