Hydraulic Rod Fault Handling Procedure
If the office chair's fault is related to the hydraulic rod (gas rod), manifested as failure to adjust height, automatic sinking, or inability to lock the height, the entire hydraulic rod needs to be replaced. The specific steps are as follows:
1. Safely Remove the Old Hydraulic Rod
- Tool Preparation: Large pipe wrench (or adjustable wrench), rubber mallet, gloves, safety goggles, lubricating oil (optional).
- Separate the Five-Star Base: Turn the chair upside down and use the pipe wrench to grip the metal collar connecting the hydraulic rod to the five-star base. Rotate counterclockwise vigorously (usually reverse-threaded) and, if necessary, drip lubricating oil to assist in loosening.
- Separate the Seat: If it is a 'snap-ring' structure, use a screwdriver to pry open and remove the metal snap-ring to pull out the hydraulic rod; if it is a 'screw-fixed' structure, unscrew the fixing screw in the center of the chassis and separate.
2. Accurately Measure and Purchase a New Rod
- Key Parameters:
- Total Length: The shortest length when the hydraulic rod is fully compressed;
- Pipe Diameter Grade: Use calipers to measure the outer pipe diameter of the original rod. Common grades are Class 3 (approximately 50mm in diameter) and Class 4 (approximately 60mm in diameter);
- Stroke: The difference between the maximum extension and minimum compression lengths.
- Purchase Advice: Bring the old rod or take precise size photos and choose to purchase a new hydraulic rod of the same size, grade, and with safety certification (such as SGS/BIFMA) online or at a hardware market. The price is approximately 30-100 yuan.
3. Install the New Hydraulic Rod
- Clean the Interfaces: Wipe the threads or interfaces of the five-star base and the seat chassis with a dry cloth to remove oil and impurities.
- Connect the Five-Star Base: Align the bottom thread of the new rod with the five-star base and rotate clockwise to tighten (first tighten by hand until secure, then slightly reinforce with a pipe wrench).
- Install the Seat: Insert the top end of the rod into the seat chassis, reinstall the snap-ring or fixing screw, place the chair upright, and repeatedly adjust the height to confirm smooth operation and secure locking.
Precautions: Wear gloves and safety goggles throughout the operation to avoid sudden ejection of the hydraulic rod or flying metal debris; if unfamiliar with the structure, it is recommended to contact professional maintenance personnel for handling.
