5. Održavanje
Regular maintenance is crucial for the longevity and optimal performance of your lawn mower.
5.1 Opće čišćenje:
- After each use, clean the underside of the mower deck to prevent grass buildup.
- Obrišite motor i vanjske površine.
5.2 Blade Maintenance:
- Redovno provjeravajte oštricu da li je oštrica naoštrena i ima li oštećenja. Tupa oštrica kida travu, što dovodi do nezdravog travnjaka.
- Sharpen or replace the blade as needed. Always use genuine PowerSmart replacement parts.
5.3 Engine Maintenance:
- Promjena ulja: Zamijenite motorno ulje nakon prvih 5 sati rada, a zatim svakih 25 sati ili godišnje.
- Filter zraka: Redovno čistite ili mijenjajte filter za zrak, posebno u prašnjavim uslovima.
- svjećica: Svjećicu pregledajte i očistite jednom godišnje. Zamijenite ako je potrebno.
5.4 Skladištenje:
- Za dugotrajno skladištenje, ispraznite rezervoar za gorivo ili dodajte stabilizator goriva.
- Clean the mower thoroughly and store it in a dry, protected area.
