For those who drive small concrete mixers, the problem of maintenance is the top priority. Everyone must want long-term benefits. Therefore, the longer the mixer can work, the higher the value it will create. Maintenance is also very important in the whole project operation. Only by doing a good job of basic maintenance can our work be carried out normally and avoid some problems and accidents.

将一张#600的砂纸置于ATF油中，浸泡约30分钟。小心地敲击阀体，使卡滞的阀杆从阀腔孔中落下。可能有必要运用一把搅拌车小螺丝刀，将其撬出。运用螺丝刀时，当心不要划伤阀孔。单向阀杆是否有痕迹。运用ATF油浸泡过的#600砂纸，打磨阀杆上的毛刺，然后在溶剂中清洗阀杆并用压缩空气吹干。

First place a piece #600 of sandpaper in ATF oil and soak it for about 30 minutes. Carefully tap the valve body to make the stuck valve stem fall from the valve cavity hole. It may be necessary to pry it out with a small mixer screwdriver. When using a screwdriver, be careful not to scratch the valve hole. Check whether there are traces on the one-way valve stem. Use the #600 sandpaper soaked in ATF oil to polish the burrs on the valve stem, then clean the valve stem in solvent and blow dry with compressed air.

卷起半张ATF油浸泡过的#600砂纸，将其刺进卡滞阀杆的阀孔中。轻轻扭动砂纸，使砂纸松卷，严密贴合在阀孔外表，然后边推拉，边扭卷砂纸，打磨阀孔。抽出#600砂纸。在溶剂中完全清洗整个阀体，然后用压缩空气吹干。在阀杆外表涂ATF油，将其落入阀孔中。阀杆应能靠自重落入阀孔底部。

Roll up half a piece of #600 sandpaper soaked in ATF oil and stab it into the valve hole of the stuck valve stem. Gently twist the sandpaper to make it loose and tightly fit on the surface of the valve hole, and then twist and roll the sandpaper while pushing and pulling to polish the valve hole. Draw out #600 sandpaper. Completely clean the whole valve body in solvent and blow dry with compressed air. Coat the surface of the valve stem with ATF oil and drop it into the valve hole. The valve stem shall fall into the bottom of the valve hole by its own weight.

不然，重复过程，从头测验。假如阀杆依然卡滞，则替换阀体。取出阀杆，用溶剂完全整理小阀杆和阀体。用压缩空气吹干一切小型混凝土搅拌车零件，然后用ATF油作为润滑剂，从头拼装。

Otherwise, repeat the process and test from scratch. If the valve stem is still stuck, replace the valve body. Take out the valve stem and completely clean the small valve stem and valve body with solvent. Dry all small concrete mixer parts with compressed air, and then assemble from scratch with ATF oil as lubricant.

了解了以上有关小型混凝土搅拌车的检修常识，咱们能够放心对混凝土搅拌车设备进行检修，咱们在挑选这些产品的时分咱们会有人士为咱们回答，还有记得收工时，要完全清洗小型混凝土搅拌车贮罐及进出料口周围，确保不粘有水泥及混凝土结块。

After knowing the above general knowledge about the maintenance of small concrete mixer truck, we can safely overhaul the equipment of concrete mixer truck. When we select these products, we will have someone to answer for us. Also, remember to completely clean the storage tank and around the inlet and outlet of small concrete mixer truck at the end of work to ensure that there is no cement and concrete caking.
