Before starting, turn around the small mixer to see the appearance of the mixer, whether there are obstacles in front of and behind the truck, whether there are suspicious oil or water stains on the ground of parking position, whether the front and rear lamp assemblies are damaged, and whether the tire pressure is enough.

检查了解搅拌车发动机的机油、冷却水是否够量，前后照明灯、信号灯和仪表是否工作正常，主要以检查水泥搅拌车内部的技术状态为主。掀起发动机罩，抽出油尺查看机油高度位置是否正常，拧开水箱盖查看水位是否正常，因为机油和冷却水是发动机的“生命保护盾”，它们出问题发动机就很容易出问题，经常检查油和水的状况是十分必要的。同时也不要忘记查看一下冷却液和制动液，这些液体的储液罐大多呈透明的，一目了然。然后将点火锁匙转到开的位置（并不是启动发动机），查看仪表板各个仪表和指示灯是否显示正常。依次开启关闭小灯、大灯、会车灯、雾灯、转向灯，故障灯、倒档灯和刹车灯等，尤其要重视转向灯和刹车灯，不管白天黑夜，这两种信号灯是关系到东风洒水车行车的，任何时候都要保持良好的状态。

To check whether the engine oil and cooling water of the mixer truck are sufficient, and whether the front and rear lights, signal lights and instruments are working normally, mainly to check the internal technical status of the cement mixer truck. Lift up the engine hood, pull out the oil dipstick to check whether the oil level is normal, and open the water tank cover to check whether the water level is normal. Because the engine oil and cooling water are the "life protection shield" of the engine, if they go wrong, the engine will easily have problems, so it is very necessary to check the oil and water condition frequently. At the same time, don't forget to check the coolant and brake fluid. Most of these liquid reservoirs are transparent and clear at a glance. Then turn the ignition key to the on position (not to start the engine), and check whether the instrument panel and indicator light display normally. Turn on and turn off the small lights, headlights, meeting lights, fog lights, turn signals, fault lights, reverse lights and brake lights in turn, and pay special attention to turn signal lights and brake lights. Regardless of day or night, these two kinds of signal lights are most related to the driving safety of Dongfeng sprinkler, and they should be kept in good condition at all times.

启动就是在前两项都正常的情况下转动点火锁匙启动混凝土搅拌车，每次启动时间不要超过十来秒，这里要注意冷启动时，压油门要轻缓渐进，切忌一启动就立即加大油门使发动机转速急剧提升，因为冷启动时曲轴转速瞬间急升，机油来不及输送到轴瓦位置，容易造成轴瓦损伤。东风洒水车启动后，密切注意油压、水温、充电筹仪表或仪表灯的变化，待仪表符合正常值或仪表灯熄灭时就可以上档开动汽车了。

Starting is to turn the ignition key to start the concrete mixer when the first two items are normal. The starting time should not exceed 10 seconds each time. It should be noted that when cold starting, the throttle should be pressed slowly and gradually. It is not allowed to increase the throttle immediately as soon as starting to make the engine speed increase sharply, because the crankshaft speed rises suddenly during cold start, and the oil can not be delivered to the bearing bush position in time The bearing bush is damaged. After the Dongfeng sprinkler is started, pay close attention to the changes of oil pressure, water temperature, charging meter or instrument lamp. When the instrument meets the normal value or the instrument lamp is off, the vehicle can be started in gear.
