1. When the concrete tanker starts, only the electromagnetic switch of the starter makes a "cluck" sound, but the crankshaft does not rotate. It may be caused by the "broken grid" of the battery.
2、当山东混凝土罐车蓄电池自放电严重，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。
2. When the battery self discharge of Shandong concrete tank truck is serious, and its polar plate and diaphragm are seriously aged, there will be a temporary stop. It can be started every time, but the parking time is long or the crankshaft can only rotate when it is started the next day. At that time, you can consider replacing the battery.
3、当极桩、极桩夹子接触不好而发热烧损，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 not in good contact and are heated and burned, you will find that the starter suddenly rotates weakly, accompanied by the smell of burning rubber or smoke from the battery.
4、当混凝土搅拌罐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 cut-in surface of the flywheel gear ring of the concrete mixing tank is deformed, there will be an idle sound of impact between the driving gear of the starter and the flywheel gear ring of the engine during startup.
5、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。
5. When the holding coil of the starter electromagnetic switch is wrongly connected to the power terminal or the three wires on the key switch are wrongly connected, as soon as the main power switch is connected, the driving gear of the concrete mixer starter will mesh with the flywheel ring gear and rotate together.
6、如果混凝土搅拌罐启动时只有轻微“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。
6. If there is only a slight "click" when the concrete mixing tank is started, and then there is no response, there can be a problem with the card issuing of the starting relay.
