4. Assembly Instructions

Follow these steps to assemble your Yaheetech Adjustable Task Chair. Basic assembly instructions are included with the product.

1. Prepare the Gas Lift: Locate the gas lift cylinder. It is crucial to remove the black plastic protective cap from the top of the gas lift before assembly. Failure to do so will prevent the chair from adjusting height.

Watch this video for a visual guide on removing the cap:

2. Attach Casters to Base: Insert the five casters into the holes at the end of each leg of the star base. Push firmly until they click into place.
3. Insert Gas Lift into Base: Place the narrow end of the gas lift cylinder (after removing the cap) into the center hole of the assembled star base.
4. Attach Seat to Gas Lift: Align the mechanism under the seat with the top of the gas lift cylinder. Carefully lower the seat onto the gas lift, ensuring it is centered and stable.
5. Test Functionality: Once assembled, sit on the chair and test the height adjustment lever and the swivel function to ensure proper operation.

6. Maintenance

To ensure the longevity and appearance of your chair, follow these simple maintenance guidelines:

• Cleaning: Wipe clean with a damp cloth. Avoid harsh chemicals or abrasive cleaners, as these may damage the faux leather or chrome finish.
• Regular Inspection: Periodically check all screws and connections to ensure they remain tight. Retighten if necessary.
• Caster Care: Keep casters free of debris (hair, dust, etc.) to ensure smooth rolling.

7. Troubleshooting

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

• Chair not adjusting height: Ensure the black plastic protective cap has been removed from the gas lift cylinder (refer to Assembly Instructions, Step 1).
• Chair feels unstable: Check that all screws are tightened and the gas lift is properly seated in the base and seat mechanism.
• Casters not rolling smoothly: Inspect casters for trapped debris and clean if necessary. Ensure they are fully inserted into the base.
