Disassembly of Adjustable Office Chairs

The disassembly of adjustable office chairs requires selecting appropriate methods based on the specific model. The disassembly steps for general models and the Be氪 Office Chair BC03Q Premium Edition are as follows:

Disassembly Steps for General Models of Adjustable Office Chairs

1. Understand the Component Composition
   Office chairs typically consist of chair legs, casters, bases, seats, gas cylinders, backrests, armrests, and headrests. Identifying the connection methods of each component (such as screw fixation or snap-fit) is the foundation for disassembly.

2. Separate the Backrest
   Most backrests are connected to the seat via screws or snaps. First, observe the connection points. If screws are used, use a screwdriver of the corresponding size to unscrew them counterclockwise. If it's a snap structure, gently shake the backrest and lift it upwards to disengage the snaps using their elasticity.

3. Detach the Base from the Gas Cylinder
   Raise the gas cylinder to its highest position. Hold the seat with one hand and press the lift lever while shaking the seat with the other hand. Repeated shaking will break the friction between the gas cylinder and the base. Once the connection is loose, they can be separated. Note: Keep the gas cylinder vertical during operation to avoid gas leakage or component damage due to tilting.

4. Detach the Gas Cylinder from the Chair Legs
   Invert the chair legs and use a rubber mallet to evenly strike the bottom of the gas cylinder. If a rubber mallet is not available, place a piece of wood between the gas cylinder and the chair legs to disperse the impact force and prevent scratches on the chair legs' surface. Control the striking force to avoid deforming the gas cylinder.

5. Disassemble Other Parts
   Armrests, headrests, and other components are usually fixed with screws. Reverse the installation order and use a screwdriver to loosen the screws for removal. If encountering stubborn screws, spray a small amount of lubricant to assist in disassembly.

Disassembly Steps for the Be氪 Office Chair BC03Q Premium Edition

1. Remove the Headrest
   Pull the headrest to its highest position, press down on the thin metal strip in the middle with force, and pull out the headrest once you feel the locking mechanism loosen. If the locking mechanism is too tight, insert a discarded hard card into the gap between the headrest and the backrest to assist in prying open the snap.

2. Remove the Armrests
   Invert the chair on a high platform (such as a workbench) and use the hex screwdriver that comes with the box to loosen the screws under the armrests. Note: Fix the chair legs during inversion to prevent sliding and accidents.

3. Separate the Backrest from the Base
   Use a hex screwdriver to remove the screws at the connection between the backrest and the base. Hold the backrest to prevent it from falling during separation.

4. Detach the Five-Star Base from the Gas Spring
   Use a rubber mallet to strike the five branches of the five-star base upwards respectively, using vibration to disengage the gas spring from the five-star base. Maintain even striking force to avoid local deformation.

5. Detach the Gas Spring from the Base
   Aim the rubber mallet at the center of the base plate and strike it to use the impact force to loosen and separate the connection between the gas spring and the base.

6. Remove the Casters
   Grasp the casters directly and pull them outwards. If the casters are stuck, shake them left and right while applying a slight upward motion to avoid breaking them due to excessive force.
