Keeping your snow blower in top condition helps you tackle winter’s worst storms. Regular maintenance ensures your machine starts reliably and performs efficiently. This guide will walk you through essential steps to prepare and maintain your snow blower, from pre-season checks to troubleshooting common issues. By following these tips, you’ll extend the life of your snow blower and be ready to clear your property with ease when the snow starts to fall.
Your Snow Blower’s Needs
Proper snow blower maintenance begins with understanding the key components of your machine and the importance of regular upkeep. By familiarizing yourself with your snow blower’s needs, you can prevent breakdowns.
Components To Check
Several critical parts of your snow blower require regular inspection and maintenance:
- Belts: These drive the auger and impeller to move snow. You’ll typically find them under the engine cover connecting the engine to the auger and impeller. Check them for wear and tension.
- Chute and auger housing: The chute directs the snow being discharged, while the auger housing is where the augers (rotating blades) collect snow from the ground. The chute is located at the top of the snow blower, and the auger housing is at the front. Make sure there are no blockages.
- Engine oil: This lubricates the engine for smooth operation. You’ll find the oil dipstick near the engine, usually marked with a bright cap. Check the level and color regularly.
- Fuel system: Comprising the fuel tank and lines, the fuel system delivers gasoline to the engine. The fuel tank is located near the top of the machine. Always use fresh gas and, when storing, use a fuel stabilizer.
- Shear pins: These small pins are located on the auger shaft, securing the auger to the drive mechanism. If the auger hits a hard object, the shear pins will break to prevent damage to the auger or gearbox.
- Skid shoes: These are located on the sides of the auger housing and control the height of the snow blower relative to the ground. They protect the machine and the surface you’re clearing. Adjust or replace them when they wear down.
- Spark plugs: These ignite the fuel in the engine for combustion. You’ll find them on the engine, typically connected to a thick wire. Check for dirt or wear and replace as needed.
- Tires: Tires provide mobility and are located at the rear of the machine. Make sure they’re properly inflated and inspect for worn tread, which can affect traction in snow.
Each of these components plays a vital role in your snow blower’s operation. Regular checks can help you identify potential issues before they become major problems.
Pre-Season Snow Blower Preparation
Before the first snowflake falls, prepare your snow blower for the season ahead. This preparation includes several key tasks that will set your machine up for success throughout the winter months.
Renewing the Fuel
One of the most common reasons for snow blower failure is old, stale fuel. Follow the steps below to avoid this issue:
- Empty the old fuel from the tank.
- Fill your gas can with fresh gasoline (no more than 10% ethanol).
- Add fuel stabilizer to the new gas.
- Fill the snow blower’s tank with this stabilized fuel.
Changing the Oil
Regular oil changes keep your snowblower’s engine from overheating and wearing down more quickly. We recommend changing the oil annually or after every 50 hours of use to keep your engine running smoothly and extend its life. Here’s how to do it:
- Run the engine for about 10 minutes to warm the oil.
- Turn off the engine and locate the oil drain plug.
- Drain the old oil into a suitable container for disposal.
- Replace the drain plug and refill with fresh oil of the correct weight.
- Dispose of the old oil properly at a recycling center.
Inspecting Spark Plugs
Spark plugs are the component that starts your snow blower, and it won’t work without them. Clean, properly gapped spark plugs ensure easy starting and efficient engine operation. To check and replace them, follow these steps:
- Remove the spark plug wire.
- Use a spark plug wrench to remove the plug.
- Inspect the electrodes for wear or damage.
- If the plug looks worn or damaged, replace it with a new one.
- Reinstall the spark plug, being careful not to overtighten.
Ensuring Optimal Snow Blower Performance
Regular checks and adjustments of the following parts will keep your machine running at peak efficiency.
Examining and Replacing Belts
Belts transfer power from the engine to the auger and drive systems. To check your belts, remove the belt cover and inspect belts for cracks, fraying, or excessive wear. Check belt tension—they should have a slight give but not be loose.
If you notice any issues, have a dealer install a new belt and check the alignment of the pulleys. This ensures proper fit and function to prevent premature wear or failure.
Adjusting Skid Shoes for Different Surfaces
Skid shoes protect your driveway and your snow blower’s scraper bar, and proper adjustment is crucial. For asphalt and concrete driveways, leave a 1/8-inch space beneath the scraper bar. For gravel driveways, set the skids for a 1-inch gap.
Conducting Tire Maintenance
Well-maintained tires provide better traction and maneuverability, so check tire pressure regularly. Inflate tires 2 psi above the recommended level to account for cold weather pressure drops. Inspect tires for wear or damage, and replace them if necessary.
Troubleshooting Common Snow Blower Issues
Even with regular maintenance, you may encounter issues with your snow blower. Knowing how to troubleshoot common problems can save you time and frustration.
Engine Won’t Start
If your snow blower won’t start, check these potential causes:
- Clogged carburetor
- Faulty spark plug
- Low oil level (on 4-cycle engines)
- Old or stale fuel
If the engine doesn’t start after a couple of pulls, take it to a dealer for service to prevent further damage.
Poor Snow Throwing Performance
If your snow blower isn’t throwing snow effectively, consider these issues:
- Clogged chute or auger
- Improperly adjusted skid shoes
- Loose or worn belt
- Worn or broken shear pins
Storage and Off-Season Care for Snow Blowers
Proper storage and off-season care help maintain your snow blower’s longevity and ensure it’s ready for the next winter. Before storage, clean your snow blower thoroughly. Remove all snow and ice from the machine, then wash the exterior with mild soap and water. Dry it completely to prevent rust, then lubricate all moving parts.
Store your snow blower in a dry, covered area. Ideally, store it indoors in a garage or shed. Keep it away from fertilizers and other corrosive materials. Cover it with a breathable cover to protect it from dust.
