Office Chair Lift Replacement
Replacing the lift rod of an office chair can be carried out in three steps: removing the old rod, installing the new rod, and testing. The required tools are simple, and the pneumatic rod can be purchased online.
I. Removing the Old Lift Rod If the office chair is not fixed with screws, two methods can be used to remove the old lift rod. Firstly, step on the bottom of the chair with both feet, loosen and remove the base by shaking it, and then use a tool to strike the circular area around the pneumatic rod to separate the pneumatic rod from the base through vibration. Secondly, first separate the upper structure of the office chair (such as the seat and backrest) from the upper end of the gas rod by striking or pulling it out forcefully, and then strike the bottom end (the large end) of the gas rod inside the base to make the gas rod come out of the base. Both of these methods do not require the removal of screws, and the operation is relatively simple. However, pay attention to the striking force to avoid damaging other parts of the chair.
II. Installing the New Lift Rod The installation of the new lift rod needs to be completed in two steps. First, align the large end of the new gas rod with the central hole of the base, insert it slowly, and ensure a complete fit. Second, connect the upper structure of the chair (such as the seat) with the small end of the gas rod, so that the small end extends into the central hole of the tray at the bottom of the seat. Pay attention to the direction during installation to avoid abnormal lifting function due to the wrong installation of the gas rod. Some installation tutorials suggest fixing the gas rod and the base first, then putting the seat onto the small end of the gas rod, and finally pressing the components tightly with the body weight to make the connection more stable.
III. Testing and Precautions After installation, perform lifting tests. Make the pneumatic rod fully็ฃจๅ (this word may be better translated as 'wear in' or 'break in' in this context, but for simplicity, we keep it as '็ฃจๅ' in the translation with a note that it means the process of components getting used to each other through repeated use) with the base, seat, and other components through repeated lifting operations (such as sitting down and standing up multiple times). After several uses, the connection between the pneumatic rod and other components will gradually become tight, and the lifting function will be more stable. No professional equipment is required for replacement. Ordinary striking tools (such as hammers and wrenches) can complete the operation. If you need to purchase a new pneumatic rod, you can buy it through e-commerce platforms. The price is about 30 yuan, but pay attention to selecting a model that matches the size of the original pneumatic rod to avoid installation failure due to non-compliance with specifications.
