1、冬季放水：冬季来临前，应将水泵和水管内的水放空，以防冻裂。我国北方一般严冬不再施工，故在施工结束后，就立即将水泵及水管内的水排空，以防后患。

1. Winter water release: Before the arrival of winter, the water in the water pump and pipes should be emptied to prevent freezing and cracking. In northern China, construction is generally not carried out in severe winter, so after the construction is completed, the water in the water pump and pipe should be immediately drained to prevent future problems.

2、停车挂档：无论是在吸水前，还是在作业前，取力装置挂档都必须在停车时进行。

2. Parking and gear shifting: Whether before absorbing water or before starting work, the power take-off device must be engaged while parking.

3、加引水：离心泵每次吸水前，必须向水泵内加入一定量的引水，加完后必须关闭加水口。水泵*次使用时，需要加引水，以后则不必再加引水。

3. Adding water: Before each suction of the centrifugal pump, a certain amount of water must be added to the pump, and after adding, the water inlet must be closed. When using the water pump * times, it is necessary to add water, and there is no need to add water in the future.

4、对水源的要求：当高压清洗机利用河沟、池塘作为水源时，注意吸水管端部全部没入水中。为避免吸入石块或较多的泥沙、漂杂物，吸水管端部一般设有过滤装置，吸水时严禁将过滤装置拆下。如果水源较浅，需要事先将吸水处挖深一些，以保证不含有杂物及不进空气。

4. Requirement for water source: When the high-pressure cleaning machine uses rivers, ditches, and ponds as water sources, pay attention to completely submerging the end of the suction pipe into the water. To avoid inhaling stones or large amounts of sediment and debris, a filtering device is generally installed at the end of the suction pipe. It is strictly prohibited to remove the filtering device when absorbing water. If the water source is shallow, it is necessary to dig deeper at the suction point in advance to ensure that there are no impurities or air intake.

5、维护保养：清洗机贮水箱设有排污管，该管的进口为水箱的zui低点。经过一段时间的使用，应定期打开排污管开关，将罐内积存的杂物排除，直到水变清为止。

5. Maintenance: The water storage tank of the cleaning machine is equipped with a drain pipe, and the inlet of this pipe is the lowest point of the water tank. After a period of use, the drain switch should be turned on regularly to remove any debris accumulated in the tank until the water becomes clear.

6、进水管必需要真空：吸水时进水管系统必须保持一定的真空度,才能将水吸入箱内。进水管系统务必要密封可靠，软管不能破损，硬管不能有裂纹，否则将产生漏气现象，也就造成吸不上水的情况。

6. The inlet pipe must require vacuum: When absorbing water, the inlet pipe system must maintain a certain degree of vacuum in order to suck water into the box. The inlet pipe system must be sealed reliably, the hose must not be damaged, and the hard pipe must not have cracks, otherwise there will be air leakage, which will result in the inability to suction water.
