Professional Instruction Manual Image Set
Correct Technical Procedure (Commercial Repair Standard)
A proper office chair gas cylinder replacement is not just “pull and replace.”
The cylinder is held in place by a friction taper fit at two connection points:
- Top taper fit → chair mechanism plate
- Bottom taper fit → five-star wheel base
There are no screws or threads on standard office chair gas lifts.
The safest and most accurate removal method is:
- Separate base from cylinder
- Separate mechanism from cylinder
- Install new cylinder using body weight compression
- Never puncture, heat, cut, or clamp the cylinder tube
This matters because office chair gas cylinders are pressurized pneumatic components.

- Large body DOWN
Many inaccurate manuals get this wrong.
Correct Removal Force
Correct:
- Shock force on hub
- Rotational release on cylinder body
Incorrect:
- Hammering piston rod
- Heating cylinder
- Cutting cylinder
Correct Tool Use
Pipe wrench:
- ONLY on outer steel tube
Never:
- On chrome rod
- On activation valve pin
