Office Chair Unloading and Installation

The unloading and installation of office chairs can be carried out according to the following steps. It is recommended to install from the bottom up, and master key separation techniques for disassembly.

Installation Steps

1. Assembly of Chair Wheels and Pneumatic Rod
   Insert each chair wheel into the assembly holes of the chair feet one by one, ensuring that each wheel is fully engaged. Then, place the thicker end of the pneumatic rod vertically against the center hole of the chair feet and gently press it until it is fully embedded. Pay attention to the direction of the pneumatic rod in this step to avoid reversing it, which could cause abnormal lifting and lowering functions.

2. Fixing the Chassis to the Seat
   Place the chassis on the bottom of the seat, and confirm the orientation according to the markings on the chassis (usually the side with the adjustment buttons faces forward). After aligning the screw holes, use the matching screws to screw them in one by one and tighten them. It is recommended to use a cross-tightening method to ensure even force distribution and prevent chassis misalignment.

3. Connecting the Seat to the Pneumatic Rod
   Align the center hole at the bottom of the seat with the top of the pneumatic rod and press down vertically until it is fully inserted into the chassis hole. If resistance is encountered, gently rotate the seat to assist in positioning and avoid forcing the press, which could damage the components.

4. Installing the Backrest
   Align the bottom sides of the backrest with the installation slots on both sides of the seat, insert them vertically, and then fix the bottom of the backrest with screws from the bottom of the armrest brackets. Subsequently, align the installation holes at the back of the backrest with the holes on the seat brackets and tighten them with screws. In this step, check whether the backrest is vertical to avoid tilting that could affect comfort.

5. Installing the Armrests and Headrest
   Align the armrests with the holes on the armrest brackets and insert them, fixing them with screws from the bottom. The headrest should be placed in the middle position at the top of the backrest and fixed with screws or buckles. After installation, test the adjustment function of the armrests and whether the height of the headrest meets the requirements.

Disassembly Difficulties and Techniques

1. Separating the Seat from the Pneumatic Rod
   Raise the pneumatic rod to its highest position, hold the edge of the seat firmly with one hand, press the lifting lever with the other hand, and gently shake the seat to gradually separate it using the lever principle. If the buckle is too tight, lightly tap the bottom of the seat with a rubber hammer to assist in loosening.

2. Separating the Pneumatic Rod from the Chair Feet
   Invert the chair feet onto a soft surface (such as a carpet), wrap the top of the pneumatic rod with a rubber hammer or a piece of wood, and evenly tap the edges of the chair feet to avoid directly tapping the pneumatic rod, which could cause deformation. After separation, check whether the port of the pneumatic rod is worn for subsequent maintenance.

Service Recommendations
If professional assistance is required, you can contact furniture disassembly and assembly technicians through platforms such as 58.com. The service scope covers office desks and chairs, conference tables, etc. When choosing a service, confirm the technician's qualifications and charging standards, and communicate the disassembly and assembly requirements in advance to ensure an efficient process.
