Set the lawn mower on the ground on its wheels.
Grasp the handle at the top, and fold it into the upright position.
Position the holes located at the bottom of the braces over the top of the pins on the bracket, so the handlebar assembly is at your desired height.
Pull the speed control rod back, then pull the braces out from the bracket to fold the handlebars back up for storage. Lean the handlebars forward, ensuring the control rod is not bent.
