Step-by-Step Snow Blower Inspection Checklist Before the First Snowfall
Before performing any servicing, start with a thorough inspection. This helps identify worn or damaged parts early, ensuring your snow blower operates safely and efficiently throughout the winter.
Auger and Impeller
The auger scoops up snow while the impeller throws it out of the chute. Together, they are the core of the snow blower’s clearing mechanism.
What to check: Look for bent, cracked, or chipped auger blades, ensure the impeller spins freely without obstruction, and verify all shear pins are intact and properly installed.
Belts and Control Cables
Belts transfer engine power to the auger and drive system, while control cables connect your handles and levers to the drive, throttle, and chute controls.
What to check: Inspect belts for wear or cracking and confirm proper tension. Test all control cables for smooth, responsive movement, lubricating or adjusting any that feel stiff.
Tires and Tracks
Wheeled models rely on properly inflated tires for traction, and tracked models use rubber or composite tracks for grip. Poor traction affects maneuverability and increases operator effort, while misaligned or worn tracks reduce snow-clearing efficiency.
What to check:For tires, verify pressure and inspect for cracks or dry rot. For tracks, check alignment, tension, and overall wear, adjusting or replacing as needed.
Fasteners, Skid Shoes, and Scraper Bar
Bolts, nuts, and screws hold the snow blower together, while skid shoes lift the auger housing, and the scraper bar clears snow from surfaces.
What to check:Tighten loose fasteners and replace corroded ones. Inspect skid shoes and scraper bars for wear and adjust or replace if necessary.
Spark Plug
The spark plug ignites the engine’s fuel-air mixture. A worn or dirty spark plug can cause hard starts, misfires, or poor engine performance in cold weather.
What to check: Remove and inspect the spark plug for carbon buildup, cracks, or worn electrodes. Clean or replace as recommended, and ensure proper gap before reinstalling.
Chute and Deflector
The chute directs snow, and the deflector controls its height and angle. A blocked or stiff chute reduces efficiency and creates safety hazards.
What to check:Rotate the chute and tilt the deflector to ensure smooth operation. Remove debris, ice, or snow buildup, and lubricate pivot points if movement is stiff.
General Cleanliness & Lubrication
Accumulated debris and lack of lubrication can lead to corrosion, wear, and reduced performance.
What to check: Clean under the auger housing, around belts, and on moving parts. Lubricate auger bearings, chute pivots, and other manufacturer-specified locations. Inspect for rust or corrosion and treat as needed.
How to Service Your Snow Blower Engine for Cold Weather Starts
Cold weather puts extra stress on snow blower engines, making proper servicing essential for reliable starts and smooth operation throughout the winter season. Neglecting these steps can lead to difficult starts, increased wear, and costly repairs.
Use Winter-Grade Engine Oil:Cold thickens standard oil, making engines harder to start. Replacing it with low-viscosity winter oil ensures better lubrication, reduces friction, and protects engine components during cold starts.
Refresh Fuel and Add Stabilizer: Stale or moisture-contaminated fuel can clog the carburetor and affect engine performance. Drain old fuel, refill with fresh gasoline, and add a fuel stabilizer to prevent fuel degradation and maintain smooth operation.
Check the Spark Plug:The spark plug is critical for consistent ignition. Inspect for carbon buildup, corrosion, or worn electrodes, and ensure the gap meets manufacturer specifications. A clean, correctly gapped spark plug improves starting reliability in low temperatures.
Maintain Electric Start/Battery:For electric-start or battery-powered models, check that connections are clean, corrosion-free, and secure. Fully charge the battery, as cold weather reduces output, preventing frustrating start failures.
Clean or Replace the Air Filter:A clean air filter ensures proper airflow and maintains the correct air-fuel mixture. This improves combustion efficiency, engine power, and fuel economy, helping the engine run smoothly even in freezing conditions.
By following these steps, your snow blower engine will start easily, run efficiently, and remain dependable throughout the snow season.
