The first step is to find out whether there are high-quality brand-name products in the purchased models. The selection should begin with the highest-winning product. The higher the award, the higher the quality. Check whether the inside and outside of the machine are firmly welded, whether the parts are deformed or broken, etc. Check whether the bolts of each connecting part of the machine are installed properly, and whether the mounting wheels of each transmission wheel, tensioning wheel and each wheel end are complete and reliable. Rotate the threshing roller and other moving parts to check for seizures and collisions. Is the operation smooth and flexible? Is there any abnormal sound in the bearings? Check whether the anti-corrosion paint on each part of the machine is even and smooth, with or without flaking and serious scratches. Locally, whether or not the quality of the paint is not high causes the mechanism to rust. Read the random instructions carefully, open the attachment box, carefully verify that the accessories are complete and in good condition, and report any problems to the sales organization in a timely manner.
