- Fuel Mixture: This is a 2-stroke engine. Mix unleaded gasoline with 2-stroke engine oil at a ratio of 25:1. Use the provided mixing bottle for accuracy. Fill the fuel tank carefully, avoiding spills.

Operation
- Starting the Engine:
- Ensure the fuel tank is filled with the correct 25:1 fuel mixture.
- Set the choke lever to the "CLOSED" position (usually indicated by a symbol or text).
- Press the primer bulb several times until fuel is visible in the return line.
- Pull the starter cord firmly and quickly until the engine attempts to start (usually 1-2 pulls).
- Once the engine "pops" or briefly starts, move the choke lever to the "OPEN" position.
- Pull the starter cord again until the engine fully starts and runs smoothly.
Video: Shows the starting procedure, including choke adjustment, priming, and pulling the starter cord.
- Using the Blower: Once the engine is running, put on the backpack unit. Hold the throttle handle firmly. The thumb-controlled, infinitely variable throttle allows you to adjust the airflow speed. Use lower speeds for delicate areas like flower beds and full power for heavy debris.

Maintenance
Regular maintenance ensures optimal performance and extends the life of your leaf blower.
- Air Filter: Regularly inspect and clean the air filter. Remove the air filter cover, take out the filter element, and clean it with warm, soapy water. Rinse thoroughly and allow it to dry completely before reinstallation. Replace if damaged.

- Spark Plug: Inspect the spark plug periodically. Clean any carbon deposits and adjust the gap if necessary. Replace the spark plug annually or if it shows signs of wear.
- Fuel System: Use fresh fuel mixture. If storing the blower for an extended period, drain the fuel tank or use a fuel stabilizer to prevent fuel degradation.
- General Cleaning: Keep the exterior of the blower clean, especially the cooling fins and air intake areas, to prevent overheating.
