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.
Do not wash the body with water
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.
Do not mix different brands of coolant
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.
Do not step on the accelerator when starting the EFI vehicle
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.
