Looking after your Lawnmower

After use, clean the housing of any debris such as grass clippings with a damp cloth or soft brush.

Storing your Lawnmower

Always keep your Lawnmower in a safe and secure location that children cannot access. Do not leave fuel sitting in your tank for long periods of time.

Staying safe

Always keep fingers and toes clear from the moving blade. If the blade is jammed, never attempt to free the blade while the Lawnmower is on.
