After performing the pre-operation inspection, open the side cover of the machine and release the abrasive belt with the tensioning arm at the rear.
After removing the abrasive belt, there are 10 different sizes of rolls on the machine. The roll bearing is designed to be easily replaced. Take the roll of your size and place it in its bed and place the abrasive belt again and stretch it. Pay attention to the direction of grinding when the abrasive belt is placed.
