Is it possible to fix a gas lift with your own hands?

Repairing such a part of the structure of any chair is not justified due to the high cost of repair labor - it is easier to replace it with a new one than to repair the old one. But, if you don’t want to waste time on a new mechanism, you can try to fix the problem yourself. This does not require special skills or knowledge - just follow the instructions.

The Ukrainian manufacturer Barski provides all its customers with a 5-year warranty on mechanisms and 2 years on upholstery materials. There are no similar offers on the market. In addition, the main misconception of the consumer is that the warranty cannot be “knocked out”; this judgment does not apply to the manufacturer Barski - all breakdowns due to the manufacturer’s fault are eliminated after the consumer’s request.

How to fix a chair if it does not rise and fall under weight?

If the chair stops responding to the adjustment process at all, and constantly falls down under the weight of a person, the gas pneumatic cartridge has broken down. The mechanical and hydraulic components of the chairs are the main difference between this furniture and a simple chair. However, this is his main problem - if you do not calculate the weight of the load correctly and buy a cheaper, but not practical product, then over time the pneumatic cartridge will release all the gas under high pressure.

To make it easier to remove the gas lift, you need to treat its base with a “bucket”.

Before carrying out repair work, you need to realize that it will not be possible to completely restore the piston, but fixing it at the same level is quite possible. To do this, a number of the following actions are carried out:

The chair turns over, the bolts from the bottom of the seat are unscrewed.
At the very bottom of the gas lift there is a special metal pin that is removed.
The crosspiece is removed from the gas lift. This is often difficult or even impossible to do, since the pneumatic cartridge “sits” tightly inside the hole of the cross, and this is normal. In order to pull the gas lift out of the hole, you need to tap it a little and, using some effort, pull the part out. It is impossible to break or break the pneumatic cartridge, so there is no need to worry.
After removing the gas lift, this part consists of two components - internal (rod, bearing and support) and external (spindle holder). As a rule, the inner part remains in the hands, and the outer part - the casing can remain inside the crosspiece, it can not be touched - it will not be needed.
Place the prepared pipe (metal-plastic, match the diameter of the inner rod of the gas lift so that it fits tightly on the piston rod) onto the rod so that about a fifth of the metal pipe remains on one side of the free space.
We put the entire structure back together - the repairs are done.

This type of repair is considered the simplest, but after this it is impossible to adjust the lifting height of the chair because there is not the required amount of gas inside, and the pipe put on the rod simply does not allow the chair to lower.

What to do if the gas lift does not turn - replace a new gas cartridge

Before carrying out work, you need to remember that the gas lift must be at room temperature - from a change from cold to hot, it can burst during disassembly. Step by step steps:

Using a shaped screwdriver, unscrew the seat from the mechanism.
Mark the front side of the mechanism.
Unscrew the 4 bolts, separating the frame from the seat.
Take a hammer and lightly hit the swing mechanism at the base of the chuck from the cross.
If you fail to knock it down, use a vice to squeeze the base of the gas lift, turning the swing mechanism.
Separate the cartridge from the crosspiece: use a metal drift to unscrew it, after spraying the bottom and top sides with WD40.
Turn the cross upward and knock the cartridge out of the conical base.
To replace a gas lift that has become unusable with a new one, insert it, applying force, into the crosspiece.
Make sure that the gas lift matches the diameter of the crosspiece.
Reattach the swing mechanism.

It is important to ensure that the arrangement of the sides of the mechanism corresponds. After replacing with a new gas lift, sit down on the seat so that the new mechanism is tightly fixed inside the hole of the cross under your weight.

Helpful Tips:

If you have problems with the gas cartridge immediately after assembling the new chair, it is likely that you received a defective gas cartridge. But before you go and complain to the sales organization and demand that the element be replaced, check whether the gas lift button is locked with a lever from the swing mechanism.
When the gas lift does not respond when the lever is pressed, check whether you have correctly secured the piastres or the swing system, and whether the lever for pressing the gas lift button is damaged.

In all other cases, it will be necessary to replace the gas cartridge.

Important! If, after reading everything about repairs, you have come to the conclusion that, for you personally, it is easier and cheaper to buy a new chair, then do not forget to read the article on how to choose a computer chair.
