5. Operating Instructions
Your tectake office chair is designed for comfort and adjustability. Familiarize yourself with its functions:
5.1. Height Adjustment
To adjust the chair's height, pull the lever located under the right side of the seat upwards. While holding the lever, either stand up to raise the chair or sit down to lower it. Release the lever at your desired height to lock it in place.
5.2. Tilt Function
The chair features a tilt mechanism for reclining. Pull the same lever outwards to enable the tilt function, allowing the chair to rock back and forth. Push the lever inwards to lock the chair in an upright position.

6. Maintenance
Proper care will extend the life of your office chair:
- Cleaning: For the faux leather and plastic parts, wipe with a soft, damp cloth. Use a mild soap solution if necessary, then wipe dry. Avoid harsh chemicals or abrasive cleaners.
- Inspection: Periodically check all screws and bolts to ensure they are tight. Retighten if loose.
- Casters: Keep the casters clean and free of debris (hair, dust) to ensure smooth rolling.

If you encounter issues with your chair, refer to the following common problems and solutions:
- Chair does not adjust height: Ensure the gas lift lever is fully engaged. If the issue persists, the gas lift cylinder may need replacement.
- Chair wobbles: Check all assembly screws and ensure they are securely tightened. Make sure the gas lift is properly seated in the base and mechanism plate.
