1. This machine should be placed in a dry environment free from any corrosive media.
2. After use, be sure to clean the inside of the cylinder and the agitator blades with clean water and dry them thoroughly. (For long-term non-use, apply rust-preventive oil to the inside of the cylinder and the surface of the blades.)
3. Regularly check whether the fasteners are loose after use and tighten them promptly.
4. When feeding materials, it is strictly forbidden to mix nails, wires, or other hard objects into the cement and sand to avoid damaging the machinery.
5. After the gearbox has been used for a period of time, check the lubricating oil level and replenish it until the oil level is visible through the inspection hole. The oil should be 30# mechanical oil.
6. In case of repair or tilting, the oil in the oil pan must be drained first. Change the oil once a quarter.
