Assembly of Deli Office Chairs

The assembly process of Deli office chairs is relatively simple, but there may be slight differences between different models, so it is necessary to operate according to the specific model and instructions.

1. General Assembly Steps
The assembly of Deli office chairs usually starts with the core components. Taking a common model as an example, the first step is to install the ball bearings or casters: Align the internal metal or plastic structure of the ball bearings with the reserved holes on the chair legs, press down vertically with slight force, and hear a 'click' sound or feel the components lock into place to complete the installation. Ensure that the ball bearings are oriented correctly to avoid installation failure or subsequent use issues due to tilting.

2. Screw Installation Precautions
For some models of chairs, screws are required to secure the backrest, armrests, or base. Pay special attention to the instructional arrows in the included manual or on the components: These arrows usually indicate the direction of screw installation or the alignment position of the components. For example, when connecting the backrest to the seat cushion, the screws may need to be screwed in from a specific direction. Incorrect direction may result in misaligned threads or misaligned components. It is recommended to control the force when using an electric or manual screwdriver to avoid over-tightening and causing the screws to strip.

3. Assembly Differences for Special Models
Take the Deli 4905 office swivel chair as an example. This model requires user assembly, but the package includes a complete office chair unit (i.e., unassembled individual components). When assembling, prioritize connecting the chair's base to the gas lift: Insert the gas lift vertically into the center hole of the base, ensuring that the metal rod is fully embedded in the rubber or plastic sleeve, and then install the five-star chair legs. Check whether the lifting function of the gas lift is normal during this step. If there is any stuttering, you may need to readjust the installation angle.

4. Post-Assembly Inspection and Adjustment
After connecting all components, perform a functional test:

• Lifting Test: Adjust the chair height using the gas lift and observe whether it operates smoothly without stuttering;
• Rotation Test: Check whether the 360-degree rotation function of the swivel chair is flexible;
• Stability Test: Sit on the chair and gently shake it to confirm that there are no loose connections or unusual noises.
  If any components are found to be loose, recheck whether the screws are tightened or whether the ball bearings are installed correctly.

Tip: Before assembly, it is recommended to count all the accessories and keep the manual until assembly is complete. If you encounter missing components or assembly difficulties, you can contact Deli's official customer service for video guidance or replacement parts.
