01
When the operator finishes operating the Wirtgen Milling Machine，Press and hold the stop button until the engine stops running，At this time, pop-up information appears on the operation screen.。The following description of this pop-up windowMistakeOne of the items is：
A. Today's Wirtgen milling machines use an automatic throttle.，Many operators are accustomed to operating milling machines with manual throttle engines.，Therefore, the operator can stop the engine by pressing the flameout button for a long time or repeatedly.，This will result in insufficient engine cooling times，As a result, a yellow pop-up message prompt appears.。
B. Pressing the stop button for a long time to manually stop the engine will cause a yellow pop-up window.，The total number of times of the alarm information prompt can also be queried when the yellow pop-up window information prompt is known through the display screen.。If such erroneous operations occur frequently，Can cause very serious damage to the engine of the equipment，For example, the turbocharger will be damaged and so on.。
C. The engine of the machine has a serious fault.，A red pop-up window appears，The operator must stop immediately to avoid further damage to the equipment。
D. The color of this pop-up window is yellow.，This kind of pop-up window is usually used to remind the equipment of abnormality.，The operator is required to take corresponding measures.。
02
The automatic grease lubrication system of the Vogler spreader can deliver grease to the distribution valve via an electronic grease pump，And then sent to each part of the main machine by the distribution valve。Following is a description of the automatic grease lubrication systemCorrectOne of the items is：
A. Pressure sensor at the location of the grease lubrication pump，Insufficient grease level in the pump tank will give an alarm，It is therefore not necessary to check the butter level every day。
B. Each part of the main engine is equipped with a separate grease nipple.，When the electric grease pump is not operating，Grease can be added manually。
C. During oil level check，The grease pump was found to be operating normally，However, the butter level does not drop or drops slowly，We can fill the pump tank with a large amount of butter for the purpose of dredging.。
D. During oil level check，Overflow of the overflow valve is found.，Disassemble the oil outlet pipe and find that the oil can flow out normally.，At the same time, there is no overflow，At this time, it is necessary to replace the overflow valve in time.。
03
During operation of the Wirtgen milling machine，The water in the water tank will pass through the first filter element and the water valve to the primary filter element.，After that, it is distributed to supply water to low-pressure and high-pressure water pumps.。The following inspection methods for insufficient water sprinkling during millingMistakeOne of the items is：
A. When the Sprinkler system pressure is insufficient，The milling process is characterized by insufficient water supply，The reason is that the filter element is blocked.。
B. The water quality of the construction site is different，The clogging situation is also different.，So，We need to clean the first filter element regularly.。
C. The second filter element can be cleaned directly with water or a brush。
D. After the first two filter elements are cleaned, if the pressure is still insufficient,，At this time, the pressure can be increased by adjusting the pressure regulating valve of the water pump，If the pressure is still low，The pressure regulating valve shall be replaced in time.。
