Steps for Repairing Hydraulic System Failures

1. Fault Confirmation: Observe whether the chair shows signs of the backrest being unable to be fixed and falling backward. Look down to check the hydraulic system at the bottom of the chair to confirm whether there is a problem with the伸缩 (extension and retraction) of the hydraulic rod.
2. Disassembly and Inspection: Lay the chair on its side (be careful as it is heavy). Start inspecting the transmission components from the backrest and test whether the拨扣 (toggle) function is normal. If the hydraulic mechanism falls off directly when pulling the toggle, focus on checking the fixing structure.
3. Component Repair:
   • Screw Replacement: Confirm that the original fixing screw is a non-standard 10*1 specification. Use a standard size 10 screw as a replacement. For thread treatment, you can use a tap tool to repair the threads or directly use a wrench to screw in the screw. Choose a screw length of 30 millimeters (slightly longer than the original). After screwing it in, add a nut to ensure it is firmly fixed.
   • Range of Motion Adjustment: Test whether the movement of the hydraulic rod is obstructed by the screw. If there is interference, add a gasket. Choose the gasket thickness according to the actual gap to ensure smooth extension and retraction of the hydraulic rod.
4. Assembly and Testing: Reinstall the repaired components in their original positions, ensuring that all screws are firmly tightened without looseness. Stand the chair up and test its functions. Repeatedly adjust the angle of the backrest to confirm that it can be fixed at any position. Check whether the extension and retraction of the hydraulic rod are smooth without jamming or abnormal noises.

Precautions

Wear protective gloves during operation to avoid scratches from metal components. If the hydraulic rod is severely leaking oil or deformed, it is recommended to replace it with a new rod (the model must match). Non-professionals should not disassemble the core components of the hydraulic system to prevent the risk of high-pressure oil spraying. This solution is applicable to backrest failures caused by damage to the fixing screws of the hydraulic rod. If it involves an explosion of the pneumatic rod or aging of the internal seals, contact professional repair personnel for handling. Avoid violent angle adjustments during daily use to extend the service life of the chair.
