Assembly of your Yaheetech office chair is straightforward and requires only a few steps. All necessary hardware and tools are provided.
Step 1: Prepare the Gas Lift
Before attaching the gas lift to the chair mechanism, it is crucial to remove the black plastic protective cap from the top of the gas lift cylinder. Failure to do so will prevent the chair's height adjustment function from working correctly.

4. Käyttöohjeet
Your Yaheetech office chair is designed for comfort and adjustability to suit your needs.
Korkeuden säätö
To adjust the seat height, pull the lever located under the seat upwards. While holding the lever, stand up to raise the seat or sit down to lower it. Release the lever to lock the height in place.
Tilt Function and Tension
The chair features a center-tilt mechanism allowing you to rock back and forth between 90-110 degrees. To activate the rocking motion, pull out the lever located under the seat. Push the lever in to lock the chair in an upright position.
You can adjust the tilt tension by turning the round knob beneath the seat. Turn clockwise to increase tension (making it harder to recline) and counter-clockwise to decrease tension (making it easier to recline).

The chair offers a full 360° swivel for easy rotation. The five caster wheels provide smooth and quiet mobility across various floor surfaces.

5. Huolto
To ensure the longevity and appearance of your chair, follow these simple maintenance guidelines:
- Puhdistus: Pyyhi puhtaaksi mainoksellaamp liinalla. Vältä voimakkaita kemikaaleja tai hankaavia puhdistusaineita, jotka voivat vahingoittaa keinonahkaa.
- Säännölliset tarkastukset: Tarkista säännöllisesti kaikkien ruuvien ja pulttien kireys. Kiristä tarvittaessa uudelleen.
- Vältä suoraa auringonvaloa: Pitkäaikainen altistuminen suoralle auringonvalolle voi aiheuttaa keinonahan haalistumista tai halkeilua.
6. Vianmääritys
Jos kohtaat ongelmia tuolisi kanssa, katso seuraavat yleiset ratkaisut:
- Tuolin korkeussäätö ei onnistu: Ensure the black plastic cap has been removed from the gas lift cylinder (refer to Assembly Step 1). Check if the height adjustment lever is fully engaged.
- Tuoli heiluu: Verify that all screws and bolts are securely tightened. Ensure the chair is on a flat, even surface.
- Pyörät eivät pyöri tasaisesti: Check for any debris or hair caught in the caster wheels. Clean them if necessary.
- Difficulty reclining/rocking: Adjust the tilt tension knob under the seat. Turn counter-clockwise to loosen the tension. Ensure the tilt lever is pulled out to enable rocking.
