15130376 Craftsman Leaf Blower / Vacuum - Overview

Hello Barb, thank you for reaching out. Washers attach the impeller to the body of the leaf blower. The impeller blades will be decentered if they become bent. This instability can cause noise while the motor is idling or cause the impeller blade to get stuck, resulting in overheating or a seized motor. A loose nut can cause a rattling noise when using your blower. The noise may be more pronounced while the blower is idling. If the impeller nut becomes lodged between the blade and the encasing, your engine may overheat and seize. If your impeller blade is bent, it can begin to rub against the sides. A piece of the blade may have broken off due to corrosion, thus causing a noise. We hope this information helps!
