When driving the automatic feeding mixer, it is inevitable to encounter problems. If it is difficult to start, what is the reason for this problem?

1、如果启动时只有轻微“嗒”的一声，之后就再没有任何反应时，就可以是启动继电器发卡出了问题。

1. If there is only a slight "click" sound when starting, and then there is no response, it can be that the starting relay is jammed.

2、当启动时只听到启动机电磁开关发出“咯咯”声，但曲轴却不转动。那就有可能是蓄电池“断格”造成的。

2. When starting, only the electromagnetic switch of the starter makes a "cluck" sound, but the crankshaft does not rotate. That may be caused by the battery "broken grid".

3、当极桩、极桩夹子接触不良而发热烧损，您启动时会发现启动机突然转动无力，并伴有烧橡胶气味或蓄电池处冒烟。

3. When the pole post and pole post clamp are burned due to poor contact, you will find that the starter suddenly turns weakly, accompanied by the smell of burning rubber or smoke from the battery.

4、当飞轮齿圈的啮合切入面变形的时候，就会出现启动时启动机驱动齿轮与发动机飞轮齿圈会发出撞击的空转声。

4. When the meshing cutting surface of the flywheel ring gear is deformed, the idling sound of the impact between the starter drive gear and the engine flywheel ring gear will appear.

5、当蓄电池自放电严重，其极板、隔板严重老化时，就会出现临时停车每次都能启动，但停车时间较长或第二天启动时却只能使曲轴转一下。那个时候您可以考虑更换蓄电池。

5. When the battery self discharge is serious, and its plate and partition board are seriously aging, it will appear temporary stop, and it can start every time, but it can only make the crankshaft turn once for a long time or the next day. At that time, you can consider replacing the battery.

6、当启动机电磁开关的保持线圈错接在了电源接线柱上或钥匙开关上的3根线接错时，电源总开关一接通，就会出现混凝土搅拌车启动机驱动齿轮就和飞轮齿圈啮合在一起转动的现象。

6. When the holding coil of the electromagnetic switch of the starter is wrongly connected to the power terminal or the three wires of the key switch are wrongly connected, as soon as the main power switch is connected, the phenomenon that the driving gear of the starter of the concrete mixer will mesh with the flywheel ring gear will appear.
