3. Setup
3.1 Assembly
Your leaf blower comes with detachable wind pipes that need to be assembled before use.

3.2 Fuel Mixing
This leaf blower uses a 2-stroke engine and requires a specific gasoline-to-oil mixture.
- Mix unleaded gasoline with premium 2-stroke engine oil at a ratio of 25:1 (25 parts gasoline to 1 part oil).
- Use a clean, approved fuel container for mixing. Shake the container thoroughly to ensure proper mixing.
- Carefully pour the mixed fuel into the blower's fuel tank. Do not overfill. The translucent tank allows for easy monitoring of the fuel level.
- Securely close the fuel tank cap.
4. Operating Instructions
4.1 Starting the Engine
- Place the blower on a flat, stable surface.
- Ensure the fuel tank is filled with the correct fuel mixture.
- Set the damper switch to the 'Choke' position (usually indicated by a closed symbol).
- Press the primer bulb several times until fuel is visible in the return line.
- Hold the blower firmly with one hand and pull the pull start handle briskly until the engine attempts to start (usually 1-3 pulls).
- Once the engine attempts to start, move the damper switch to the 'Run' position (open symbol).
- Pull the pull start handle again until the engine starts.
- Allow the engine to warm up for a few moments before applying full throttle.
4.2 Using the Blower

Figure 4.1: Proper handling of the leaf blower during operation.
- Hold the blower firmly with both hands if necessary, using the main handle.
- The throttle trigger on the handle allows you to adjust the wind intensity. Press it gently for lower speed and fully for maximum power.
- Sweep the blower from side to side, directing debris into piles.
- Avoid blowing debris towards windows, vehicles, or other objects that could be damaged.
4.3 Stopping the Engine
To stop the engine, simply press the engine stop switch located on the handle. The engine will immediately shut off.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your leaf blower.
5.1 Cleaning
- After each use, ensure the engine is off and cool.
- Clean the exterior of the blower with a damp cloth. Avoid using harsh chemicals.
- Remove any debris from the air intake and protective mesh cover to ensure proper airflow and prevent overheating.
- The wind pipe is detachable for easy cleaning and storage. Clean any accumulated debris from inside the pipe.
5.2 Fuel System
- Always use fresh fuel mixture. Do not store mixed fuel for extended periods (more than 30 days).
- If storing the blower for a long period, drain the fuel tank and run the engine until it stops from lack of fuel to clear the carburetor.
5.3 Storage
- Store the blower in a dry, well-ventilated area, away from direct sunlight and extreme temperatures.
- Keep out of reach of children and unauthorized persons.
