As long as the new small concrete mixer is regularly maintained for the first two years, there will basically be no problem. When the small concrete mixer is used for more than two years, some easily worn parts will not be replaced regularly. What parts need to be replaced irregularly? Let's introduce:

1、不定期的更換發動機潤滑油

1. Replace the engine lubricating oil irregularly

一般情況下，廠家會要求用戶在行駛5000公里-1.5萬公里的時候更換潤滑油，而增壓小型混凝土攪拌車發動機車型則要求在行駛5000公里的時候更換，如果小型混凝土攪拌車不怎么開或者一直處于停駛狀態，每半年更換一次機油。當然，如果司機所處的環境以及油品質量都還不錯，可以適當的延長換油周期和時間。

The oil is changed every half a year when the small mixer is driven for - 50000 kilometers, but the user usually requires the engine to be changed every half a year when the mixer is driven for - 5000 kilometers. Of course, if the driver's environment and oil quality are good, the oil change cycle and time can be appropriately extended.

2、不定期更換機油濾芯

2. Replace the oil filter element irregularly

機油濾芯的作用就是過濾雜質，因此要與機油一同更換。如果不更換的話，機油得不到過濾從而導致小型混凝土攪拌車發動機內部零件因機油中的雜質加速磨損。

The function of the oil filter element is to filter impurities, so it should be replaced with the oil. If it is not replaced, the oil cannot be filtered, resulting in accelerated wear of internal parts of small concrete mixer engine due to impurities in the oil.

3、不定期更換空氣濾芯

3. Replace the air filter element irregularly

如果濾芯阻塞嚴重，將使進氣阻力增加，小型混凝土攪拌車發動機功率下降。同時由于空氣阻力增加，也會增加吸進的汽油量，導致混合比過濃，從而使小型混凝土攪拌車發動機運轉狀態變差，增加燃料消耗，也容易產生積炭。平時應該養成經常檢查小型混凝土攪拌車空氣濾清器濾芯的習慣。

If the filter element is blocked seriously, the air inlet resistance will increase and the engine power of small concrete mixer will decrease. At the same time, due to the increase of air resistance, it will also increase the amount of gasoline absorbed, resulting in excessive mixing ratio, which will worsen the running state of small concrete mixer engine, increase fuel consumption and easily produce carbon deposition. At ordinary times, the habit of checking the air filter element of small concrete mixer truck should be formed.

4、不定期更換剎車油

4. Replace the brake oil irregularly

剎車油有一個特點就是會吸收空氣中的水份，而小型混凝土攪拌車剎車液壓系統要讓剎車油與大氣相通才能正常運作，久而久之剎車油就會吸入水份，在高溫下轉成氣泡，當小型混凝土攪拌車剎車油路中出現氣泡，剎車效能就會下降。所以剎車油是要根據氣候、運行環境、季節變化及工況等及時檢查其質量性能按時更換的。

One characteristic of brake oil is that it will absorb water in the air. The brake hydraulic system of small concrete mixer truck can operate normally only if the brake oil is connected with the atmosphere. Over time, the brake oil will absorb water and turn into bubbles at high temperature. When bubbles appear in the brake oil circuit of small concrete mixer truck, the braking efficiency will decline. Therefore, the quality and performance of brake oil should be checked and replaced on time according to the climate, operating environment, seasonal changes and working conditions.

一般建議：每兩年或者行駛5萬公里的時候更換，而在選擇和更換剎車油的時候也要切記：不同類型的剎車油不要混合使用。由于配方不同，混合剎車油會造成剎車油指標下降。

General recommendation: replace it every two years or when driving 50000 kilometers, and remember when selecting and replacing brake oil: do not mix different types of brake oil. Due to different formulations, mixed brake oil will reduce the index of brake oil.

5、不定期更換防凍液

5. Replace the antifreeze from time to time

防凍液長時間不換，其中的防腐、防銹和防垢功能將會降低，這樣會造成小型混凝土攪拌車冷卻系統故障甚至發生銹蝕。一般來說，防凍液一般每1.5年-2年更換一次。

If the antifreeze is not changed for a long time, the functions of anti-corrosion, anti rust and anti scaling will be reduced, which will cause the failure or even corrosion of the cooling system of small concrete mixer. Generally speaking, the antifreeze is generally replaced every 1.5-2 years.
