Maintenance Tips
- Inspect Auger and Impeller: Regularly check the auger blades and impeller for damage or wear. Replace damaged components promptly to maintain optimal performance.
- Check and Replace Shear Pins: Shear pins protect the auger gearbox. Inspect them before each use and replace any that are broken or damaged. Use only the correct replacement shear pins.
- Oil Changes and Fuel Stabilizer: Change the engine oil annually, following the manufacturer's recommendations. Add fuel stabilizer to the fuel tank before storing the snow blower for the off-season to prevent fuel degradation.
