5、在施工現場卸料完畢后，應立即用攪拌車隨帶的軟管沖洗進料斗、出料斗、卸料溜槽等處，清除粘附在車身各處的污泥及混凝土。在返回攪拌站的途中，應向攪拌筒內注150---200L水以清洗筒壁及葉片粘結的混凝土殘渣。

5. After unloading at the construction site, the hose accompanying the mixer shall be used to wash the feeding hopper, discharging hopper, discharging chute and other places, and the sludge and concrete adhered to the vehicle body shall be removed. On the way back to the mixing plant, 150-200l water shall be injected into the mixing drum to clean the concrete residue stuck on the wall and blades.

6、每天工作結束后，司機應負責向攪拌筒內注入清水并高速（14—18轉/分）旋轉5—10分鐘，然后將水排去，以保證筒內清潔。用高壓水清洗攪拌筒各個部分時，應注意避開儀表及操縱桿等部位。壓力水噴嘴與車身油漆表面間的距離不得小于40厘米。

6. At the end of each day's work, the driver shall be responsible for injecting clean water into the mixing drum and rotating it at high speed (14-18 RPM) for 5-10 minutes, and then draining the water to ensure the cleanness of the drum. When cleaning all parts of the mixing drum with high-pressure water, pay attention to avoid the instrument, control lever and other parts. The distance between the pressure water nozzle and the body paint surface shall not be less than 40 cm.

7、清除攪拌筒內外積污及殘存的混凝土渣塊時，以及在機修人員進入筒內進行檢修和焊補作業時，需先關閉汽車發動機，使攪拌筒完全停止轉動。在機修人員進入筒內工作期間，必須保證拌筒內通風良好，空氣新鮮，無可然氣體及有害灰塵，氧氣供應充足（不得使用純氧）。在筒內使用電動工具操作時，操作人員必須有良好的絕緣保護。

7. When removing the accumulated dirt and residual concrete slag inside and outside the mixing drum, and when the mechanic enters the drum for maintenance and repair welding, the car engine shall be shut down first to completely stop the mixing drum. During the period when the mechanic enters the mixing drum, he must ensure that the mixing drum is well ventilated, the air is fresh, there is no natural gas and harmful dust, and the oxygen supply is sufficient (pure oxygen is not allowed). When using electric tools to operate in the cylinder, operators must have good insulation protection.

8、工作時，不得將手伸入旋轉的攪拌筒內，嚴禁將手伸入主卸料溜槽和加長卸料溜槽的連接部位，以免發生事故。

8. During operation, do not extend your hand into the rotating mixing drum. Do not extend your hand into the connection between the main discharge chute and the extended discharge chute to avoid accidents.
