Before storing, clean the mower thoroughly, drain the fuel or add a fuel stabilizer, change the oil, and store it in a dry, cool place. Disconnect the spark plug to prevent accidental starting.
To adjust the cutting height, locate the height adjustment levers on each wheel. Move the levers to the desired position, ensuring all four wheels are set to the same height.
