6. Održavanje
Pravilna njega produžit će vijek trajanja i izgled vaše stolice:
- Čišćenje: The faux leather upholstery is water-resistant and easy to clean. Wipe clean with a damp krpom. Izbjegavajte jake kemikalije ili abrazivna sredstva za čišćenje.
- Inspekcija: Povremeno provjeravajte sve vijke i matice kako biste bili sigurni da su čvrsto pričvršćeni. Po potrebi ih ponovno zategnite kako biste održali stabilnost i spriječili škripanje.
- Kotačići: Kotačiće držite čistima od ostataka (kose, prašine) kako biste osigurali glatko kotrljanje.

7. Rješavanje problema
Ako naiđete na bilo kakve probleme sa svojom stolicom, pogledajte sljedeća uobičajena rješenja:
- Škripanje stolice: Check and tighten all assembly screws. Lubricate moving parts if necessary.
- Podešavanje visine ne radi: Provjerite je li poluga plinskog podizača potpuno učvršćena. Ako problem i dalje postoji, možda je potrebno zamijeniti cilindar plinskog podizača.
- Stolica se ne kotrlja glatko: Inspect casters for trapped debris (e.g., hair, carpet fibers) and clean them. Ensure the chair is used on an appropriate surface.
- Stolica se čini nestabilnom: Verify that all screws are securely tightened and the base is properly assembled. Do not exceed the maximum weight capacity.
