Office Chair Separation Video Translation

Currently, no complete video tutorial specifically targeting 'office chair separation' has been found, but the operation can be completed by combining relevant disassembly videos with written instructions. The 'separation' of an office chair usually refers to disassembling components such as the seat, backrest, armrests, and base into independent modules, which is common in scenarios like repair, cleaning, or transportation. The following provides step-by-step guidance based on existing video resources and general disassembly logic:

I. Preparations Before Separation

1. Tool Preparation
   Most office chair disassembly requires screwdrivers (Phillips/flat-head), wrenches or Allen wrenches (common for fixing screws on five-star bases), rubber hammers (for tapping clips), etc. Some videos mention that hard cards (such as bank cards) can be used to assist in separating clip structures to avoid scratching components with tools.

2. Safety Precautions
   Place the chair on a flat surface to prevent it from tipping over during disassembly; if the chair has a gas lift, release the pressure first (by repeatedly pressing the lift button to the lowest position); wear gloves to prevent hand injuries from metal components.

II. Core Component Separation Steps

1. Seat and Base Separation
   Refer to the method for 'disassembling the base of an adjustable-height swivel chair' in video:

   • Flip the chair so that the seat faces up and observe the connection point between the base and the seat (usually a central gas lift or metal bracket);
   • Use a wrench to loosen the fixing screw at the top of the gas lift (some models may require removing the decorative cover first);
   • If the connection is a clip structure (common in low-end models), gently tap the edge of the seat with a rubber hammer or insert a card to pry the clip. Keep the seat balanced during separation to prevent the gas lift from suddenly popping out.

2. Backrest and Seat Separation
   Refer to the modular design of the 'Bekr Office Chair' in video:

   • Check if there are hidden screws at the connection point between the backrest and the seat (usually located at the bottom or side of the backrest);
   • After unscrewing the screws, hold both sides of the backrest and lift upwards (some models may require pressing clips simultaneously);
   • If the backrest is fixed with plastic pins, use a screwdriver to gently pry the head of the pin to loosen it.

3. Armrest Separation
   According to the tutorial 'without professional tools' in video:

   • The connection between the armrests and the seat is usually fixed with screws (located under or on the side of the armrests);
   • After unscrewing the screws, the armrests may be stuck due to long-term use. Wiggle the armrests left and right and slowly lift them to separate them;
   • If the armrests are clip-on, press the clips on both sides simultaneously and pull them outwards.

III. Precautions

• Record the Disassembly Order: Take photos to record the positions of each component before separation to avoid incorrect installation during reassembly;
• Handle with Care: Plastic components (such as the backrest shell) are prone to breakage, so avoid violent disassembly;
• Gas Lift Handling: If separating the gas lift from the five-star base, use specialized tools or have it done by a professional to prevent high-pressure gas from spraying out and causing injury.
