1. The equipment is in good condition, the spindle has no deformation, no radial runout, the installation is firm and fixed, and there is no vibration, etc.
2. Check whether the saw blade is damaged, whether the tooth shape is complete, whether the saw board is smooth and flat, and whether there are any other abnormalities to ensure safe use.
3. When assembling, ensure that the arrow direction of the saw blade is consistent with the rotation direction of the equipment spindle.

4. When installing the saw blade, keep the shaft, chuck, and flange clean. The inner diameter of the flange should be consistent with the inner diameter of the saw blade. Make sure the flange and saw blade fit snugly. Install the dowel pin and tighten the nut. The flange size should be appropriate, and the outer diameter should not be less than 1/3 of the saw blade diameter.
5. Before starting the equipment, ensure that there is a single person operating the equipment and idling it under safe conditions. Check whether the equipment rotates correctly and whether there is vibration. After installing the saw blade, let it idle for a few minutes. If there is no slipping, swinging, jumping, etc., it is normal.
