Dismantling a Folding Office Chair

Dismantling a folding office chair requires step-by-step operations, with the core focus on separating the gas cylinder, chair legs, and other components. The specific methods are as follows:

I. Basic Dismantling Steps (Applicable to Ordinary Folding Office Chairs)

1. Separating the Backrest from the Seat
   If the backrest is fixed with screws or clips, first rotate the screws counterclockwise or press the clips to unlock them, and then remove the backrest from the seat. For some chairs where the backrest and seat are integrated, this step can be skipped.

2. Removing the Base and Gas Cylinder

   • Raise the gas cylinder to its highest position to increase the gap between components.
   • Hold the seat firmly with one hand and press the lift lever (usually located beneath the seat) with the other hand while gently shaking the seat to separate the base from the gas cylinder. If the connection is too tight, lightly tap the edge of the base with a rubber mallet to help loosen it.

3. Separating the Gas Cylinder from the Chair Legs

   • Invert the chair legs (with the five or four claws facing upwards) and tap the top of the gas cylinder with a rubber mallet (or use a wooden board as a cushion). Apply even force while tapping to avoid deforming the gas cylinder or damaging the chair legs.
   • If the gas cylinder and chair legs are tightly connected due to long-term use, spray a small amount of lubricant (such as WD-40) onto the connection and let it sit for 5 minutes before tapping again.

4. Removing the Armrests and Headrest

   • The armrests are usually fixed to the sides of the seat with screws. Use a screwdriver of the corresponding size to rotate the screws counterclockwise to remove them.
   • If the headrest is designed to be removable, first locate the fixing clips or screws and separate them by following the reverse order of installation.

II. Additional Steps for Special Folding Structures (e.g., Hospital Accompany Chairs)

1. Expanding the Chair to Its Initial State
   Some folding chairs (such as hospital accompany chairs) need to be expanded by lifting the bottom and pulling it in the opposite direction to ensure that all folding joints are fully opened and to avoid jamming during dismantling.
2. Dismantling According to Basic Steps
   After expansion, follow the order of "separating the backrest - removing the base - separating the gas cylinder - removing the armrests" as described above.

III. Safety Precautions

• Protective Measures: Wear gloves during dismantling to avoid cuts from metal components. If the gas cylinder is aged, keep it away from your face during dismantling to prevent the ejection of high-pressure gas inside.
• Tool Selection: Preferably use a rubber mallet (to reduce damage to components). The screwdriver should match the screw size to avoid slipping.
• Handling Long-Used Components: If the gas cylinder and chair legs are tightly connected, do not forcefully pry them open. It is recommended to contact a professional or use specialized dismantling tools.
