How to ensure that the installation direction of saw blade of cutting machine is not backward?

1. The rotating direction of the saw blade should be consistent with the direction marked by the machine body. Seen from the front, the cutting blade rotates clockwise, and the rotating direction of the blade is consistent with the direction marked on the fuselage.

2. Before installing the saw blade, turn on the power supply, start the motor to see the rotation direction of the spindle, which should be consistent with the sawing direction of the saw blade, and then install the saw blade after it is confirmed. See that the sawtooth opening direction of the saw blade should be consistent with the forward direction; If you are not sure whether it is installed correctly, try to cut the material without putting it in. If the saw blade is installed backwards, the sawing noise will be loud, the sawtooth will break and the aluminum will stick.
