Maintenance Tips
- Inspect Auger and Impeller: Regularly check the auger blades and impeller for wear, damage, or bending. Replace worn or damaged parts promptly to maintain optimal performance.
- Check and Replace Shear Pins: Shear pins protect the auger and gearbox from damage if a hard object is encountered. Always have spare shear pins on hand and replace them immediately if broken.
- Fuel Stabilizer for Storage: Add fuel stabilizer to the gas tank before storing the snow blower for the off-season. This prevents fuel from degrading and causing starting problems in the fall.
- Adjust Skid Shoes: Periodically check and adjust the skid shoes to ensure proper clearance and prevent damage to the scraper blade and the surface you're clearing. Adjust them higher for gravel surfaces and lower for paved surfaces.
