3. Drain the oil and water in the oil and water container before each use.
4. After each use, please inject 2-3 lubricating oil into the air inlet and let the grinder run idling for 3-5
seconds. This is very important.
5. If the water is added too much, the machine has the function of liquid level protection and does not
work.
6. Please be careful not to freeze the water in winter.
7. In order to extend the service life of the dust extractor, it is recommended that a single continuous use
time does not exceed 20 minutes.
8. In order not to affect the service life of the dust extractor, it is recommended to clean the barrel, filter,
and dust barrier in time after each use.
9. After the work is completed, wind the power cord and insert the accessories into the accessory rack
10. Discharge the sewage promptly after absorbing water. Various rubbish in the sewage can easily make
the barrel rusty or corrode the barrel.
11. Please clean the surface of the vacuum cleaner with a dry cloth. Do not wipe it with a wet cloth to
prevent it from entering the dust extractor, otherwise it will cause a short circuit or even burn the dust
extractor.
