• Stability: Always sit properly in the chair. Avoid standing on the chair or using it as a step stool.
• Children: Keep children away from the assembly area. Small parts can be a choking hazard.
• Maintenance: Regularly check all screws and connections to ensure they remain tight. Tighten if necessary.

3. Assembly Instructions

Follow these steps carefully to assemble your tectake office chair. It is recommended to assemble the chair on a soft, clean surface to prevent damage.

1. Attach Wheels to Base: Insert the five double wheels into the openings at the end of each leg of the star-shaped base. Push firmly until they click into place.
2. Insert Gas Lift: Place the gas lift cylinder into the central hole of the assembled base. Ensure it sits securely.
3. Attach Mechanism to Seat: Align the seat mechanism (the metal plate with levers) to the underside of the seat cushion. Secure it with the provided screws, ensuring the front of the mechanism faces the front of the seat.
4. Attach Armrests: Secure the armrests to the sides of the seat cushion using the designated screws. Do not overtighten initially.
5. Attach Backrest: Connect the backrest to the armrests or the seat mechanism (depending on design) using the appropriate screws. Once all connections are made, tighten all armrest and backrest screws evenly.
6. Connect Seat to Base: Carefully place the assembled seat and backrest onto the gas lift cylinder, ensuring the gas lift's top fits into the mechanism's central opening. Apply gentle downward pressure to secure.

4. Operating Instructions

4.1. Height Adjustment

To adjust the seat height:

• To raise: While standing, pull the lever located under the right side of the seat upwards. The seat will rise automatically. Release the lever at the desired height.
• To lower: While seated, pull the lever located under the right side of the seat upwards. The seat will lower. Release the lever at the desired height.

4.2. Tilt Function

The chair features a dynamic tilt function for enhanced comfort and flexibility.

• To activate/deactivate tilt: Pull the lever (often the same one used for height adjustment, or a separate one on the left) outwards to allow the chair to recline. Push it inwards to lock the chair in an upright position.
• Adjusting Tilt Resistance: Rotate the round knob located under the front of the seat mechanism. Turn clockwise to increase tilt resistance (making it harder to recline) and counter-clockwise to decrease resistance (making it easier to recline).

4.3. Swivel Function

The chair offers a full 360-degree swivel, allowing for easy movement and access to different areas of your workspace without needing to reposition the entire chair.

5. Maintenance

Proper care will extend the life and appearance of your tectake office chair.

• Cleaning: The synthetic leather and mesh upholstery are easy to clean. Wipe surfaces with a soft, damp cloth. For stubborn stains, use a mild soap solution and then wipe with a clean, damp cloth. Avoid harsh chemicals or abrasive cleaners.
• Inspection: Periodically inspect all screws, bolts, and connections. Tighten any loose fasteners to ensure the chair remains stable and safe.
• Wheels: Keep the wheels free of hair, dust, and debris to ensure smooth movement.
• Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause the upholstery to fade or crack.

6. Troubleshooting

If you encounter any issues with your chair, refer to the following common solutions:

• Chair Squeaks: Check and tighten all screws and bolts. A small amount of silicone spray on moving metal parts (avoiding the gas lift cylinder) may help.
• Chair Wobbles: Ensure all screws are fully tightened and the base is correctly assembled. Verify the gas lift is properly seated in the base and mechanism.
• Height Adjustment Not Working: Check if the gas lift lever is fully engaged. Ensure no obstructions are preventing the gas lift from moving freely. If the gas lift is faulty, it may need replacement.
• Wheels Not Rolling Smoothly: Clean any debris (hair, lint) from the wheel casters.
