    Petrol Lawnmower Maintenance

    Whichever type of lawnmower you use, and whether it’s a Qualcast, Flymo, or other leading brand, the right maintenance will keep your lawnmower in top condition and running better for much longer. Here are a few pointers.

    For information on how to tackle and resolve faults and problems on a wide range of appliances see our other articles »

    Petrol Lawnmower

    • Always check the manual for guidelines.

    • Manufacturers may recommend different things, but a general rule of thumb is to change the oil on your lawnmower after every 25-50 hours of operating.

    For a lot of households, this will probably be about once a year, so change it every spring to keep it fresh for the summer ahead. When oil loses its freshness it will turn darker.

    • The oil level should be checked on the dip stick after every 8 hours of mowing.

    • Always use the fuel recommended by the manufacturer. Bear in mind that unleaded petrol will go stale if it is stored for more than 3 months. This can affect the engine performance.

    • Keep your spark plug on form. This will need replacing after every 100 hours of use.

    • Clean the air filter every season or after every 25 hours of mowing. It may need replacing if very dirty.

    • Clean the mower deck housing using soap and water. To do this you need to disconnect the spark plug. If there is a heavy build-up of grass you may need to use a scraper first.

    • Keep the blades on your mower sharp with a grinder wheel or a file. If the blade is really damaged then you will need to replace it.

    • Replace any worn and torn belts.

    • Keep a maintenance schedule to help keep you on track with your lawnmower.

    • Keep it in good storage during winter months.
