5.1 Fuel Mixing

This is a 2-stroke engine and requires a specific fuel mixture. Use the provided oil pot for accurate mixing.

• Fuel Type: Use 93# gasoline.
• Engine Oil: Use high-quality 2-stroke engine oil.
• Mixing Ratio: Mix gasoline and 2-stroke engine oil at a ratio of 25:1 (25 parts gasoline to 1 part oil).
• Procedure: Pour the correct amount of 2-stroke oil into the oil pot, then add the corresponding amount of gasoline. Shake the mixture thoroughly before pouring into the mower's fuel tank.

5.2 Starting the Engine (Hand-Pull Start)

1. Fill Fuel Tank: Ensure the fuel tank is filled with the correct 25:1 gasoline/oil mixture.
2. Prime (if applicable): If your model has a primer bulb, press it several times until fuel is visible.
3. Choke: Move the choke lever to the 'CLOSED' or 'START' position (usually for a cold engine).
4. Throttle: Set the throttle control to a mid-range position.
