5. Priežiūra
Regular maintenance ensures the longevity and safe operation of your Windgoo E20.
- Akumuliatoriaus priežiūra: Reguliariai įkraukite akumuliatorių, net jei jo nenaudojate, kad palaikytumėte jo būklę. Laikykite akumuliatorių vėsioje, sausoje vietoje. Venkite dažno visiško akumuliatoriaus iškrovimo.
- Padangų slėgis: Check tire pressure before each ride. Maintain the recommended pressure (usually indicated on the tire sidewall) for optimal performance and safety. The 3.0-inch fat tires provide better traction across various surfaces.

- Grandinė: Grandinę laikykite švarią ir suteptą, kad išvengtumėte rūdžių ir užtikrintumėte sklandų pavarų perjungimą.
- Valymas: Nuvalykite dviratį su damp cloth and mild soap. Avoid high-pressure washing, especially near electrical components. Dry thoroughly after cleaning.
- Bendra apžiūra: Periodiškai patikrinkite visus varžtus, veržles ir greito atleidimo svirtis, kad įsitikintumėte, jog jie yra tvirtai ir patikimai priveržti.
