Key Points for Long-Term Storage and Maintenance of Gasoline-Powered Leaf Blowers (Backpack / Handheld)

Key Points for Long-Term Storage and Maintenance of Gasoline-Powered Leaf Blowers (Backpack / Handheld)

I. Preparations Before Stopping and Storing

1. Thoroughly Cool Down

Turn off the machine and wait for it to completely cool down before proceeding to prevent burns and fuel tank fires.

2. Empty / Dispose of Fuel (Most Important)

If not in use for over a month: Drain all gasoline from the fuel tank, start the machine at idle speed until it automatically shuts off, and burn off any remaining fuel in the carburetor and fuel lines.

Consequences of not doing this: Gasoline will evaporate and form gum, clogging the carburetor, fuel lines, and fuel injectors, making it difficult to start the machine next time or even causing it to be scrapped.

3. Clean Up Debris

Clear leaves, soil, grass, and dust from the blower tube, air intake, and fan blades.

Use a brush or air blower to clean the radiator fins and cylinder cooling gaps. Do not directly spray water into the engine.

4. Air Filter Maintenance

Foam filter: Clean, squeeze dry, and air dry. Apply a thin layer of engine oil and reinstall.

Paper filter: Blow off dust. Replace if too dirty. Clogging can cause the machine to stall or lose power.

5. Spark Plug Inspection

Remove the spark plug, clean carbon deposits, and check the electrode gap.

Add 5-10 ml of two-stroke engine oil to the cylinder and pull the starter 2-3 times to lubricate the cylinder wall. Reinstall the spark plug.

6. Check Lubrication and Components

Apply a small amount of engine oil to the throttle cable and air damper rod to prevent rust.

Check for cracks or aging in the air ducts, clamps, and shock-absorbing rubber sleeves.

II. Storage to Prevent Moisture and Rust

1. Storage Environment

Store in a dry, well-ventilated, and cool indoor area. Keep away from damp floors, outdoor rain, and direct sunlight.

Elevate the machine off the ground to prevent corrosion of the chassis and components due to ground moisture.

2. Whole Machine Protection

Cover with a dust cover or plastic bag to protect from dust, moisture, and dirt.

Lay the air duct flat and avoid hard folding or flattening to prevent cracking and deformation.

3. Power Cord / Starter Rope

Straighten the starter rope and do not leave it taut and stuck.

Set the machine switch to the off position.

III. Regular Maintenance for Long-Term Storage

Check every 1-2 months for moisture, rust, or rodent damage.

If stored for more than six months: Replace the mixed oil, check the spark plug and air filter before starting the machine next time.

IV. Pre-Startup Inspection

Check for aging, cracking, or oil leakage in the fuel lines.

Re-mix the proper two-stroke engine oil.

Ensure the blower tube and interfaces are securely installed and the screws are tightened.

Test the idle speed and air damper before operation.
