1. First, get a new belt tensioner.
2. Then, align the tensioning wheel with the bolt position on the generator and place it on the generator. Bolt positions must be consistent; otherwise, subsequent installation may be affected.
3. Insert the screw into the bolt hole of the tensioning wheel and tighten the bolt using a wrench.
4. Turn the bolts of the fastening wheel anticlockwise and wrap the belt around the generator to install.
