As the last leaves fall and winter approaches, it’s time to put away your backpack leaf blower. Proper winter storage is crucial for extending the life of your equipment, ensuring it starts reliably next spring, and preventing costly repairs. Neglecting a few key steps can lead to issues like fuel system clogs, battery degradation, and rust. Whether you own a gas-powered or a battery-powered model, a little preparation goes a long way in protecting your investment.
Why Winter Storage is Essential
The cold temperatures, humidity, and inactivity of winter can be harsh on outdoor power equipment. Specific concerns include:
- Fuel Degradation (Gas Models): Gasoline, especially ethanol-blended fuel, can break down over time, forming gummy deposits that clog fuel lines and carburetors. This is the most common reason for a gas blower failing to start after winter.
- Battery Degradation (Battery Models): Storing lithium-ion batteries fully charged or fully depleted in extreme cold can reduce their overall lifespan and capacity.
- Corrosion and Rust: Moisture and condensation can lead to rust on metal components, particularly the engine parts, fan, and fasteners.
- Plastic and Rubber Damage: Extreme cold can make plastic components brittle and cause rubber seals to crack, leading to leaks or reduced performance.
- Pest Infestation: Rodents and insects can find warm, sheltered spots inside the blower’s air filter housing or other crevices, causing blockages and damage.
Winter Storage for Gas-Powered Backpack Leaf Blowers
Gas models require more attention for winter storage due to their fuel systems.
1. Fuel System Preparation
This is the most critical step. You have two main options:
- Run the Fuel System Dry:
- Add a high-quality fuel stabilizer to the fuel tank and run the engine for 5-10 minutes to ensure the stabilized fuel circulates through the carburetor.
- Then, empty the fuel tank completely.
- Start the engine and let it run until it completely runs out of fuel and stalls. This ensures all fuel is removed from the carburetor, preventing gumming.
- Store with Stabilized Fuel:
- Fill the fuel tank completely with fresh, stabilized fuel (using a high-quality fuel stabilizer according to product instructions). Filling it completely minimizes air space, reducing condensation.
- Run the engine for 5-10 minutes to ensure the stabilized fuel reaches all parts of the fuel system.
- Note: While convenient, running dry is generally the safest option to prevent fuel-related issues.
2. Engine and Spark Plug Care
- Clean the Engine: Thoroughly clean the exterior of the engine, especially the cooling fins, to remove any dirt, dust, or debris that could trap moisture.
- Lubricate Cylinder (Optional but Recommended): Remove the spark plug. Pour a teaspoon of clean two-stroke engine oil into the spark plug hole. Gently pull the starter cord a few times (without letting the engine start) to distribute the oil, lubricating the cylinder walls and preventing rust. Reinstall the spark plug.
Winter Storage for Battery-Powered Backpack Leaf Blowers
Battery models are simpler but still require specific care for their power source.
1. Battery Care
- Remove Batteries: Always remove the battery pack from the blower.
- Charge Level: Store lithium-ion batteries at a partial charge, typically around 50-60%. Storing them fully charged or fully depleted for long periods can shorten their lifespan.
- Storage Environment: Store batteries in a cool, dry place, away from direct sunlight and extreme temperatures (both hot and cold). Avoid unheated garages or sheds if temperatures drop below freezing for extended periods.
General Storage Tips for All Backpack Leaf Blowers
Regardless of fuel type, these steps apply to all models:
- Thorough Cleaning: Give the entire blower a comprehensive cleaning. Remove any caked-on dirt, leaves, grass, and sap from the fan intake, blower tube, and all exterior surfaces. Clean the air filter (and replace if heavily soiled or damaged).
- Inspect for Damage: While cleaning, inspect the blower for any signs of wear, cracks, loose fasteners, or damage to the harness system. Address any issues now so it’s ready for spring.
- Lubricate Moving Parts: Lightly lubricate any exposed metal moving parts (e.g., throttle linkage on gas models) with a silicone spray or light oil to prevent rust.
- Store in a Dry, Protected Area: Choose a clean, dry, and well-ventilated storage location. Avoid damp basements or areas prone to significant temperature fluctuations. A shed, garage, or workshop is ideal.
- Protect from Pests: Consider placing the blower in a sealed plastic bag or container to deter rodents and insects from nesting inside.
- Proper Orientation: Store the blower upright or as recommended by the manufacturer. Ensure it’s stable and won’t tip over.
Conclusion
Taking the time to properly prepare your backpack leaf blower for winter storage is a small effort that yields significant rewards. By following these guidelines for fuel system care, battery maintenance, and general cleaning, you can protect your equipment from the elements and ensure it’s ready to roar to life when spring arrives, saving you from headaches and unexpected repair costs.
