Your mower offers three cutting options:

5. Održavanje

Redovno održavanje osigurava optimalne performanse i produžava vijek trajanja vaše kosilice. Uvijek isključite kabel svjećice prije bilo kakvog održavanja.

5.1 Generalno čišćenje

After each use, clean grass clippings and debris from the mower deck, wheels, and engine cooling fins. Use a brush or cloth. Avoid using high-pressure water directly on the engine.

5.2 Održavanje motora

  • Promjena ulja: Zamijenite motorno ulje nakon prvih 5 sati rada, a zatim svakih 25 sati ili godišnje.
  • Filter zraka: Redovno provjeravajte i čistite filter za zrak. Zamijenite ako je oštećen ili prekomjerno prljav.
  • svjećica: Inspect the spark plug annually. Clean or replace as needed.

5.3 Njega oštrice

Regularly inspect the cutting blade for sharpness and damage. A dull blade tears grass, leading to an unhealthy lawn. Sharpen or replace the blade as necessary. Always wear heavy gloves when handling the blade.
