Replacement Method: When replacing an office chair hydraulic rod, first raise the chair to its highest position. Then, use a large hammer to gently tap the seat part and the wheel frame to knock out the old hydraulic rod. If the old hydraulic rod is difficult to remove, lubricate it with oil to make it easier to disassemble. Next, insert the new hydraulic rod into the corresponding position.
Maintenance Methods:
- If the chair cannot be raised or lowered, it may be due to poor internal sealing of the hydraulic rod or a faulty control valve. For sealing issues, invert the chair and carefully use tools to disassemble the connection between the hydraulic rod and the seat. Check if the sealing rubber ring is damaged. If damaged, purchase a compatible sealing rubber ring for replacement and reassemble it. If the control valve is faulty, try cleaning the valve to remove any possible impurities. If the issue persists after cleaning, replace the control valve with a new one.
- If the hydraulic rod makes abnormal noises, it may be due to a lack of lubrication or loose components. For a lack of lubrication, use professional hydraulic oil or lubricating oil and drip an appropriate amount onto the moving parts of the hydraulic rod. Then, repeatedly raise and lower the chair to evenly distribute the lubricating oil. If components are loose, use a wrench or other tools to tighten the loose screws.
Disassembly Method (for New Chairs): For new chairs, if you need to disassemble the hydraulic rod, first raise the chair to its highest position. Then, hold the chair with your hands, invert it, and place it steadily on a flat surface.
