5. Vedligeholdelse
Regular maintenance ensures optimal performance and extends the life of your lawn mower. Always disconnect the spark plug cap before performing any maintenance.
5.1 Rengøring

- Remove the grass collection bag and empty it.
- Tilt the mower onto its side (with the carburetor facing upwards to prevent oil leakage) and scrape off any accumulated grass clippings from the underside of the deck.
- Rengør udvendigt med adamp cloth. Do not use a high-pressure washer directly on the engine or electrical components.
