Video: EMIAH GT100 Chair Assembly Guide. This video demonstrates the step-by-step assembly process for the chair.
- Step 1: Mounting Nylon Casters and Connecting Base and Gas Lever
Insert the five nylon casters into the assembly holes of the chair base. Then, insert the gas lever into the central assembly hole of the base. - Step 2: Install the Battery Underneath the Seat Cushion
Turn the seat cushion over. Use a small wrench to remove the two marked screws from the battery mounting plate. Remove the battery from the mounting plate. First, install the battery mounting plate, making sure the latch is facing upwards. Then snap the battery onto the mounting plate, ensuring the connector is facing downward. Securely connect the two cables. - Step 3: Attach Base and Backrest
Remove the plastic protective cover from the metal pins on the backrest. Lift the backrest up and insert it into the seat cushion. Use a wrench to remove the three screws at the backrest connection and keep them safe. Flip the seat cushion over and place it on a cardboard box or another support. Slide the metal plate on the backrest into the base, aligning it with the three screw holes, and then install the screws. Secure the clips of the two white connecting wires. - Step 4: Connect the Upper and Lower Halves
Carefully align the upper and lower halves of the chair and connect them, ensuring all wires are properly routed and secured.

- Cleaning: Wipe clean with a soft, damp cloth. Avoid harsh chemicals or abrasive cleaners that may damage the PU leather.

- Caster Care: Keep casters free of hair and debris to ensure smooth rolling.
6. Troubleshooting
If you encounter any issues with your EMIAH GT100-Y chair, please refer to the following common solutions:

Video: How to Restoring Backrest to 90 Angle? This short video demonstrates how to reset the backrest to its upright position.
- Creaking Noise: Ensure all assembly screws are securely tightened. If the noise persists, identify the source of the creaking and apply a small amount of silicone lubricant to moving metal parts, avoiding contact with upholstery.
- Difficulty Adjusting Height/Recline: Check that the control levers are fully engaged or disengaged as intended. Ensure no obstructions are preventing movement.
- Footrest Issues: Verify that the footrest mechanism is clear of obstructions and that it slides smoothly.
