1,  Before the new machine leaves the factory, the lubricant in the cam chamber and the transmission chamber has been discharged. The user should fill lubricant before using it for the first time.
2, Concrete workability has a great influence on the continuity, stability, spray effect and production efficiency. Max. grain size should be no more than 15mm and slump should be strictly controlled within 10~15cm.
3, Don’t run the Wet Mix Concrete Spraying Equipment with system air pressure under 0.5 MPa.
4, The start-up and shut-down must strictly observe the operating procedures of the Wet Mix Concrete Spraying Equipment .
5, If there is large pulse and a blockage in the nozzle (working air pressure rises sharply), turn off main motor immediately.
6, During spraying, ensure discharge hole of rotor is unobstructed.

7, Make sure there is no concrete accumulation on connection interface of rotor body and the cam bushing during spraying.

8, clean thoroughly after using:
     1.Open wind path, add water to hopper, clean spray hoses with water and wind.

     3.Clean non-return valve of liquid accelerator hose and filter
9, Wet Mix Concrete Spraying Equipment should be checked thoroughly every month or after completing 300m3 of concrete spray (adjust check period depending on spray quantity.

Then replace it every six months(depending on the amount of injection). Replace lubricant of dosing pump every month during the first six months. Then replace it every six months.
