The pneumatic cylinder functions by releasing air when the user pulls the appropriate lever while sitting on the chair, and springing back up when the user pulls the lever while standing. But when the seal on the cylinder fails or internal mechanism becomes damaged, the adjustment no longer works properly. Fixing this common problem requires only a hammer, little expertise, and a replacement cylinder. By purchasing a new pneumatic chair cylinder on eBay, buyers can save both time and money compared to buying from the manufacturer. Whether complete or partial failure of the pneumatic cylinder occurs, cylinder replacement remains the easiest, most sensible solution.
If the chair does not move from the lowest setting, users can assume complete cylinder failure has occurred. If the seat slowly sinks over the course of the day, then only partial cylinder failure has occurred. Repair of the leaky cylinder, however, is not usually practical. If the height adjustment of the chair works fine but the seat wobbles, this indicates a problem with the base or wheels. In this case, users should simply tighten all screws at the base and replace damaged parts. In cases involving cylinder failure, the manufacturer of the specific chair can provide a replacement cylinder, usually with installation instructions. If the chair has an active warranty, the manufacturer may replace the cylinder at no cost. Since these cylinders have a standardized size across the industry, eBay vendors also offer many standard pneumatic cylinders that fit just about any pneumatic chair, often at prices lower than the manufacturer offers for chairs without a warranty. The following table lists the common symptoms, diagnoses, and solutions for pneumatic desk chair repair.
Chair locks in position and does not rise Chair slowly sinks with use, but does rise Chair wobbles, but rises and adjusts properly Problem with wheels and/or chair base Tighten parts at base and check for damage, replace damaged parts As the table shows, basically two categories of issues exist: problems with the pneumatic cylinder and problems with the base. Adjustment troubles indicate a cylinder malfunction, while stability issues mean the problem resides at the base. Replacing a faulty desk chair cylinder requires only some basic tools and know-how. For this task, users need a hammer or heavy mallet and a new replacement cylinder. Aside from that, this process requires no additional parts or tools. The pneumatic cylinder connects to the chair seat without any hardware. To remove it, first turn the chair upside down. Then firmly tap the area round where the cylinder connects to the bottom of the seat while holding on to the base. Users should take care to tap evenly on all side of the cylinder.
Eventually, the connection loosens and the cylinder comes out. Just like the upper connection, this lower connection has no hardware involved. They cylinder simply wedges into the base assembly. To remove it, hold the base upside down. Firmly tap on the exposed portion of the cylinder until it disconnects from the base. It falls to the floor, so put down padding if necessary to prevent damage to the floor from the metal cylinder. Since no hardware exists, installing the new cylinder takes only a few simple steps. First, put the base on the floor right side up. Insert the bottom of the new cylinder into the hole where the old cylinder fit, pushing in firmly. Then, with the seat on the floor upside down, push the connected base and cylinder into the hole at the bottom of the seat firmly. Set the chair upright and push down firmly. Test the adjustment mechanism to make sure it works properly. Since all standard pneumatic cylinder desk chairs use the same width cylinder, buyers find many suitable options on eBay by searching for " pneumatic cylinder chair replacement ."
