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.

不要用水冲洗车身

Do not wash the body with water

内部夏天到了，常见私家车主们一边用水冲洗车身，一边用抹布擦拭，在此要提醒搅拌车司机的是：车身内部更好不要用水直接冲洗。因为驾驶室内地板胶垫的下面可不是“一马平川”，结构上的需要使驾驶室地板胶垫下面的凹槽、通孔非常多。用水冲洗后，要么沉积在凹槽内不易干燥，要么从通孔处流到自动上料搅拌车变速箱等部件上产生锈蚀。尤其是密封性能较好的自动上料搅拌车更不能用水直接冲洗车身内部。正确的方法是用湿抹布擦拭，但要避免积水。

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.

不同企业的冷却液不要混合使用

Do not mix different brands of coolant

谁都知道自动上料搅拌车发动机冷却液不足时应及时添加，但司机是否把不同企业的冷却液温在一起使用了呢?如果是，劝司机还是趁早把冷却液放掉，重新添加同一企业的冷却液。因为不同企业的冷却液其化学性能可能相差悬殊，比如对黑色金属有效的防腐剂，却常常对自动上料搅拌车铝制品有腐蚀作用;而适用于铝台金的防腐剂则对铁合金有害。由于不同企业的冷却液所用的防腐剂不同，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.

电喷车启动时不要踩油门

Do not step on the accelerator when starting the EFI vehicle

启动自动上料搅拌车发动机前踩几脚油门，是许多驾驶员的习惯，尤其是在冬季冷车启动时。但这种启动方法却不适用于电喷轿车。装有电控喷油装置的自动上料搅拌车发动机与普通化油器式发动机不同，它的喷油控制装置能根据发动机的温度、工况自动调整供油量，使自动上料搅拌车发动机顺利启动，即在冷车启动时，喷油控制装置能自动增加供油量。所以，自动上料搅拌车发动机启动时，没有必要踩油门，更不要在启动前连续急踩，否则反而使自动上料搅拌车发动机启动不良。

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.
