Check all of the nuts, bolts, screws, belts, and cords to make sure that nothing is loose. Two-stage snow blowers have two belts, one for the auger and one for the drive; single-stage snow blowers have only one belt. If the belts are worn or cracked, they should be replaced. Otherwise, make sure they are tight. Having these parts and accessories on hand is helpful for snow blower maintenance and repair, however we have them available with quick and easy shipping!
