5. Huolto
Regular maintenance ensures the longevity and optimal performance of your lawnmower. Always ensure the engine is off and the spark plug cap is removed before performing any maintenance.
5.1 Puhdistus
- Puhdista leikkuulaitteen alapuoli jokaisen käyttökerran jälkeen, jotta ruohonkertymät eivät pääse vaikuttamaan leikkuutehoon.
- Clean the exterior of the engine and housing with a damp cloth. Do not use high-pressure washers directly on the engine.
- Tyhjennä ja puhdista ruohonkerääjä säännöllisesti.
5.2 Terän hoito
Inspect the cutting blade regularly for sharpness and damage. A dull or damaged blade can lead to poor cutting quality and increased engine strain. Blades should be sharpened or replaced by a qualified service technician.
5.3 Moottorin huolto
- Öljynvaihto: Vaihda moottoriöljy ensimmäisten 5 käyttötunnin jälkeen, sen jälkeen 25 käyttötunnin välein tai vuosittain, kumpi tahansa tulee ensin.
- Ilmansuodatin: Puhdista ilmansuodatin säännöllisesti, erityisesti pölyisissä olosuhteissa. Vaihda vaurioitunut suodatin.
- Sytytystulppa: Tarkasta ja puhdista sytytystulppa vuosittain. Vaihda kulunut tai likainen tulppa.
5.4 Varastointi
For long-term storage, ensure the fuel tank is empty or treated with a fuel stabilizer. Clean the lawnmower thoroughly and store it in a dry, well-ventilated area. The foldable handle allows for compact storage.
