Setup and Assembly

Before first use, some assembly is required. Ensure all components are present and undamaged.

  1. Handle Assembly:

    Unfold the handle and secure it in the operating position using the easy-to-operate handle lock levers. Each side of the handle can be locked and unlocked with a single action without tools.

  2. Grass Catcher Attachment:

    Assemble the 30-liter grass catcher if it came disassembled. Attach the grass catcher to the rear of the lawnmower. Ensure it is securely fitted to prevent grass clippings from escaping.

Operating Instructions

  1. Adjusting Cutting Height:

    The cutting height can be adjusted from 20mm to 75mm using the single lever located on the side of the mower. Select the appropriate height for your lawn conditions. For best results, avoid cutting more than one-third of the grass blade length at a time.

  2. Starting the Lawnmower:

    Ensure the child lock key is inserted. Press the lock-off button and then pull the switch lever towards the handle to start the mower. The soft start feature ensures smooth activation. Release the lock-off button once the motor starts.

  3. Mowing Technique:

    Push the mower at a steady pace. Overlapping each pass slightly will ensure an even cut. For optimal grass collection, ensure the grass catcher is not overfilled. For mulching, remove the grass catcher and ensure the mulching plug (if included) is correctly installed.

Maintenance

Regular maintenance ensures the longevity and safe operation of your lawnmower.

  • Blade Inspection and Cleaning:

    Regularly inspect the blade for sharpness and damage. A dull or damaged blade can lead to poor cutting performance and excessive battery drain. Clean grass clippings from the blade and cutting deck after each use. Always remove the battery before inspecting or cleaning the blade.

  • General Cleaning:

    Wipe down the exterior of the mower with a damp cloth. Do not use harsh chemicals or abrasive cleaners. Avoid spraying water directly onto electrical components.
