BELT REMOVAL, REPLACEMENT and ADJUSTMENT

missing. Belts that are too loose or too tight will not give good service and will not last as long. Replacing and /or ad-
justing belt should be performed using maximum cauton. Protective shielding will need to be removed to replace the
belt or adjust the belt tension.
