1. Snow Blower Maintenance

Regular snow blower maintenance ensures your machine runs smoothly when you need it most. Whether you’re prepping for winter or storing your unit during warmer months, proper upkeep improves performance, prevents breakdowns, and extends the life of your snow blower.

1.1. Tools & Material Need

Before beginning any snow blower maintenance, it's important to gather all the necessary tools and materials. Having everything on hand, from basic wrenches to safety gear will help make the process smoother, more efficient, and safer. This checklist ensures you're fully prepared before diving into the maintenance steps:

Wrench and socket set
Screwdrivers (flathead and Phillips)
Spark plug wrench
Clean rags or paper towels
Engine oil (as specified in your manual)
Fuel stabilizer
Replacement spark plug (optional)
Air filter (if applicable)
Degreaser or mild detergent
Lubricating oil or spray (e.g., WD-40)
Safety gloves and goggles

Having these materials ready will make the maintenance process faster and safer.

1.2. Step by Step Guide to Maintain Snow Blower

Follow these steps to perform basic snow blower maintenance:

Step 1: Turn Off and Disconnect Power

Before beginning any maintenance, you should always turn off the snow blower and disconnect the spark plug. This precaution helps prevent accidental startups while you’re working on the machine.

Step 2: Drain or Stabilize Old Fuel

If there is still fuel in the tank, you have two options: either drain it completely or add a fuel stabilizer. This step prevents the formation of varnish and clogs in the carburetor during storage. Stabilized fuel also helps keep internal parts protected while the machine is not in use.

Step 3: Change the Engine Oil

To change the oil, place a container underneath the drain plug and remove the plug to let the used oil drain completely. After the oil has fully drained, you should refill the engine with fresh oil that matches the manufacturer's recommended specifications. Replacing old oil ensures the engine stays lubricated and protected during the off-season.

Step 4: Inspect and Replace the Spark Plug

Remove the spark plug carefully and examine it for any signs of dirt, corrosion, or wear. If the spark plug is damaged or heavily soiled, you should clean it or replace it with a new one. A clean, functional spark plug is essential for reliable engine starting in the next season.

Step 5: Clean the Machine

Use a soft brush or clean cloth to remove any snow, salt, or dirt from the exterior of the snow blower. If you encounter stubborn grease or grime, a mild degreaser can help loosen and remove buildup. Make sure to clean critical areas like the auger and discharge chute thoroughly, as residue in these areas can cause performance issues.

Step 6: Lubricate Moving Parts

Apply a light lubricant to key moving parts, including the auger, chute rotation mechanism, and control joints. Lubricating these components reduces friction, prevents rust, and keeps them functioning smoothly during operation.

Step 7: Check Belts and Cables

Inspect the drive and auger belts for any signs of cracking, stretching, or fraying. Test the belt tension and adjust it if necessary. In addition, check the control cables for wear or looseness, and make any needed adjustments to maintain proper responsiveness.

Step 8: Inspect Tires or Skid Shoes

Examine the tires to ensure they are properly inflated and show no signs of excessive wear. For snow blowers equipped with skid shoes, inspect them for wear and replace them if they are worn down. Proper traction and clearance are critical for safe and effective snow removal.

Step 9: Store Properly

Before storing the snow blower for the off-season, make sure it is thoroughly cleaned and dried. If you haven’t done so already, drain the fuel or add stabilizer to protect the fuel system. Finally, store the machine in a dry, covered location to prevent rust and damage from moisture or temperature fluctuations.

2. Storing Snow Blower Tips

Properly storing your snow blower at the end of the season is just as important as maintaining it during use. Without the right storage practices, moisture, fuel residue, and rust can damage key components, making your machine harder to start or even unusable next winter. Here are essential tips to help you store your snow blower safely and effectively:

2.1. Drain or Stabilize the Fuel

Leftover gasoline can gum up your carburetor and fuel lines.

Option 1: Run the machine until the fuel tank is empty.
Option 2: Add a fuel stabilizer, run the engine for a few minutes to circulate it, then turn it off.

2.2. Clean the Entire Machine

Dirt, salt, and snow residue left on your snow blower can lead to corrosion and rust over time. Use a damp cloth or a low-pressure hose to clean the exterior, including the auger housing, chute, and wheels. Make sure to wipe down all surfaces and let the unit air dry completely before storing, trapped moisture is one of the biggest enemies of long-term storage.

2.3. Lubricate Moving Parts

Lubricating your snow blower's moving components helps prevent rust and ensures smoother operation when you're ready to use it again. Spray light machine oil or silicone-based lubricant on areas like the auger shaft, chute controls, bearings, and wheel axles. Don’t forget to check any linkages or cables. Proper lubrication can extend their lifespan significantly.

2.4. Disconnect or Replace the Spark Plug

Removing the spark plug before storage is a simple safety measure to prevent accidental starts during handling or transport. While it's removed, consider adding a small amount of engine oil into the cylinder, then gently pull the starter cord to distribute it, protects the internal engine parts from corrosion. If your spark plug is old or showing wear, replace it now so the machine is ready to go next season.

2.5. Check Belts, Bolts, and Cables

Over time, belts can stretch or crack, and bolts may loosen due to vibration during use. Inspect the drive and auger belts for any signs of wear, and tighten any loose fasteners. Also, make sure control cables are functioning smoothly and not frayed, replacing them during storage avoids last-minute repairs when snow hits.

2.6. Cover and Store in a Dry Place

Store your snow blower in a well-ventilated, dry area like a garage or shed to protect it from humidity and temperature swings. Avoid using plastic covers, which can trap moisture and lead to rust; instead, choose a breathable fabric cover designed for outdoor power equipment. Make sure the snow blower is parked on a dry surface and away from any items that might tip or fall onto it.

3. FAQs about Snow Blower Maintenance

3.1. How often should you change the gear oil in a snowblower?

You should typically change the gear oil in a snowblower every 1 to 2 years, or after about 50 hours of use, depending on your model and how frequently it's operated.

3.2. Should I spray my snowblower with WD-40?

Yes, spraying certain parts of your snow blower with WD-40 or a similar water-displacing lubricant can be beneficial, especially for preventing rust. Use it on exposed metal components such as the auger, chute, and control cables. However, avoid spraying it on belts or friction discs, as it may cause slipping or reduce effectiveness. For long-term storage, applying WD-40 helps protect against corrosion and moisture damage.

3.3. What is the best lubricant for a snowblower?

The best lubricant for a snow blower depends on the part you're servicing:

Use high-quality synthetic grease or lithium-based grease for gears, axles, and auger shafts.
Apply silicone spray or dry graphite lubricant for control linkages and cables.
Use engine-safe oil for internal engine components and a light protective spray like WD-40 for metal surfaces prone to rust.

A well-maintained snow blower not only runs better, it keeps you safer in tough winter conditions.
