During the maintenance of the wheels of the automatic loading mixer, a few mixer drivers applied lubricating oil on the bolts and nuts in an ingenious way to prevent rust on the wheels. However, this practice is not only wrong, but also brings certain hidden dangers to the driving safety of the automatic loading mixer. After the bolts and nuts are tightened, they are self-locking. After applying lubricating oil, the self-locking coefficient between the two becomes smaller and the self-locking performance decreases. When the self-feeding mixer is running at high speed, the bolts and nuts are easy to loosen or even fall off, thus causing the driving accident of the self-feeding mixer.

不要用水沖洗車身

Do not wash the body with water

內部夏天到了，常見私家車主們一邊用水沖洗車身，一邊用抹布擦拭，在此要提醒攪拌車司機的是：車身內部更好不要用水直接沖洗。因為駕駛室內地板膠墊的下面可不是“一馬平川”，結構上的需要使駕駛室地板膠墊下面的凹槽、通孔非常多。用水沖洗后，要么沉積在凹槽內不易干燥，要么從通孔處流到自動上料攪拌車變速箱等部件上產生銹蝕。尤其是密封性能較好的自動上料攪拌車更不能用水直接沖洗車身內部。正確的方法是用濕抹布擦拭，但要避免積水。

It is summer inside. It is common for private car owners to wash the car body with water while wiping it with rags. Here, we should remind the mixer driver that it is better not to wash the car body directly with water. Because the bottom of the cab floor rubber pad is not "flat", the structural needs make the grooves and through-holes under the cab floor rubber pad very many. After washing with water, either it is deposited in the groove and is not easy to dry, or it flows from the through-hole to the gearbox and other parts of the automatic feeding mixer to produce rust. In particular, the automatic loading mixer with good sealing performance cannot directly wash the interior of the vehicle body with water. The correct method is to wipe with a wet cloth, but avoid water accumulation.

不同品牌的冷卻液不要混合使用

Do not mix different brands of coolant

誰都知道自動上料攪拌車發動機冷卻液不足時應及時添加，但司機是否把不同品牌的冷卻液溫在一起使用了呢?如果是，勸司機還是趁早把冷卻液放掉，重新添加同一品牌的冷卻液。因為不同品牌的冷卻液其化學性能可能相差懸殊，比如對黑色金屬有效的防腐劑，卻常常對自動上料攪拌車鋁制品有腐蝕作用;而適用于鋁臺金的防腐劑則對鐵合金有害。由于不同品牌的冷卻液所用的防腐劑不同，所以不能混合使用。

Everyone knows that the engine coolant of the automatic feeding mixer should be added in time when it is insufficient, but does the driver use different brands of coolant temperature together? If yes, advise the driver to drain the coolant as soon as possible and add the same brand of coolant again. Because the chemical properties of different brands of coolant may vary greatly, for example, the effective preservative for ferrous metals often has corrosive effect on aluminum products of automatic feeding mixer; However, the preservative applied to aluminum and titanium is harmful to ferroalloy. Because different brands of coolant use different preservatives, they cannot be mixed.

電噴車啟動時不要踩油門

Do not step on the accelerator when starting the EFI vehicle

啟動自動上料攪拌車發動機前踩幾腳油門，是許多駕駛員的習慣，尤其是在冬季冷車啟動時。但這種啟動方法卻不適用于電噴轎車。裝有電控噴油裝置的自動上料攪拌車發動機與普通化油器式發動機不同，它的噴油控制裝置能根據發動機的溫度、工況自動調整供油量，使自動上料攪拌車發動機順利啟動，即在冷車啟動時，噴油控制裝置能自動增加供油量。所以，自動上料攪拌車發動機啟動時，沒有必要踩油門，更不要在啟動前連續急踩，否則反而使自動上料攪拌車發動機啟動不良。

It is the habit of many drivers to step on the accelerator before starting the engine of the automatic feeding mixer truck, especially when it is cold in winter. However, this starting method is not applicable to EFI cars. The engine of the automatic feeding mixer equipped with an electronic fuel injection device is different from the ordinary carburetor engine. Its fuel injection control device can automatically adjust the fuel supply according to the temperature and working conditions of the engine, so that the engine of the automatic feeding mixer can start smoothly, that is, when the cold car starts, the fuel injection control device can automatically increase the fuel supply. Therefore, it is not necessary to step on the accelerator when the engine of the automatic feeding mixer is started, let alone step on it continuously before starting, otherwise the engine of the automatic feeding mixer will not start properly.
