DIY gas lift repair

If an office chair sags under you, then the so-called break in it. gas lift is a mechanism responsible for lifting and fixing the chair. A new part costs 600-800 rubles, plus something will need to be paid for the work of the master. But the gas lift may not be changed, but simply fixed once and for all in one - convenient for us! - position.

The work is really for two minutes - you need to remove the crosspiece with the gas lift, use the pedal to push it up to the end and put something on the rod that will prevent it from going down. A piece of rubber hose will work best (it will feel softer on the chair), but it can be replaced with a metal, polypropylene tube, or even a set of washers.

Here is a great video with instructions, I made my chair on it, and everything worked out:

• - Serviceable gas lift;
• - crosshead screwdriver;
• - rubber or metal hammer;
• - vice;
• - annular drift.

A common cause of gas lift breakdowns is that you do not sit correctly on the chair, that is, do not distribute the weight over the entire area of ​​the seat, but do the main load on its front edge.

Manufacturers of office furniture prohibit using Gaslift at temperatures below +5 degrees. At lower temperatures, the liquid in it freezes, and under load it immediately breaks. If you buy a chair in the cold season, then you can start assembling it only 24 hours after its components are in a warm room.

Sometimes it is necessary to repair the gas lift for kitchen furniture, for this you need to familiarize yourself with its operating principle. Fittings are very important for kitchen furniture. This includes hinges, handles, fasteners, guides and gas lifts. High-quality furniture is not cheap: it is about thirty percent of the total cost of furniture.

The gas lift is a bracket that raises and lowers the wall cabinet door and locks it in the open position. Such a mechanism for the kitchen consists of the following elements:

• housing, with nitrogen;
• rod moving along the body;
• bearings that ensure uniform movement of the stem;
• parts that maintain tightness: bushing, oil seal, boot, sealing element;
• fasteners details.

The stem is attached to the door with all the accessories. There are different performances. If installed incorrectly, there may be distortions. In this case, not only aesthetics are lost, but also functionally the mechanism will not provide its purpose. Before installation, you need to markup for fasteners. The mechanism must match the design of the cabinet. So, if its internal space has a height of 365 mm, then the gas lift should have a length of 355 mm.

When installing a gas lift, the base of the device is fixed in the side of the cabinet in a preliminary

the intended place. The bracket is screwed into the marked location and the elevator head snaps into the bracket.

In some designs, the base is a plate with a hole, installed on the screws in the side so that the center of the hole coincides with the marked mark. Next, the hinge head is inserted into this hole and secured. Do not deform the plate to avoid malfunction.

Installation on the inner surface of the doors is carried out in the same way. In this case, the angle of inclination of the hinge should be approximately 8 degrees. Checking the correct direction is carried out with the stem extended at its maximum.

When choosing a gas lift, you need to know the weight of the doors on which it will be installed. The heavier the door, the greater the holding force must be.There are mechanisms that are configured for automatic mode: when the doors are open, after a certain period of time, they are triggered and closed. This is convenient when the hostess forgot to close the locker, or when they are hanging very high.

When buying a gas lift, you need to pay attention to the manufacturer. The best are German and Italian movements. You can pick up Polish options from the available assortment. Recently, Chinese enterprises have also improved their quality. Selection criteria: material of manufacture and the force that is applied to close the door. A high-quality gas lift will serve for a long time and flawlessly if used correctly.

Gas lift is a sealed structure. Gas is pumped into the cylinder of the mechanism during manufacture. Such

the device cannot be repaired, so you should not open it yourself. The entire system is under pressure. With a loss of tightness, the gas lift will not cope with its functions. To avoid unpleasant phenomena, it is better to invite a specialist for repairs. The sealed system can even explode.

However, there are minor defects during operation: the gas lift mounts can relax during operation. The doors begin to creak when opened. To eliminate the defect, you need to tighten them. Another option to get rid of an unpleasant squeak is to lubricate parts. In conclusion, it should be noted that the gas lift must be treated very carefully, since the mechanism cannot be repaired, and in the event of a breakdown, you will have to throw out the expensive device and install a new one.

Unlike cabinet furniture, an armchair is subject to increased wear and tear, since, in addition to daily use, it contains mechanical, and most importantly, hydraulic parts.

So why, for one owner, the chair broke down after half a year, while for the other it serves for years without a single breakdown? This circumstance does not always depend on the quality of a particular model. First of all, of course, you need to pay attention to the weight of the user, as well as care during operation. In any case, most modern chairs are designed for a weight of up to 120 kilograms, and manufacturers, in turn, give a guarantee for any breakdown from 12 to 18 months.

But if your chair breaks down and the warranty period has already passed, then, having sufficient dexterity, you can easily repair the computer chair yourself. However, we recommend that you turn to professionals in organizations specializing in this.

If your computer chair lowers itself when you sit down, and rises when you get off it, while the period of lowering or lifting can vary from a few seconds to a day, this is a clear sign of gas escaping from the gas cartridge. Gas lifts cannot be repaired, as their disassembly is life-threatening.

In this situation, you can fix the chair in the required position with improvised means or replace the gas cartridge with a new one. The cost of the gas cartridge is not great, and you can buy it at any specialized store.

So, you have made the decision to replace the gas cartridge yourself.

• Armchair
• Curly screwdriver
• Rubber hammer
• Metal drift
• New gas cartridge (appropriate length and diameter)
• Vise (for more convenience)

1. If you carry out repairs during the cold time of the day, then the liquid in the gas lift may freeze, in this state it is strictly forbidden to use it. Wait for the new gas cartridge to warm up to room temperature (this will require leaving it up to 24 hours).
2. The first step is to unscrew the seat from the swing mechanism or piastra with a curly screwdriver. Turn the chair over, mark the face of the rocking mechanism, unscrew the 4 screws holding the chair seat to the rocking mechanism, and set the chair body aside.
3. Move the protective casing, take the gas cartridge in your left hand with the swing mechanism downward and with medium-force blows start tapping the swing mechanism at the base of the gas cartridge, make sure that you do not bend the swing mechanism. If it was not possible to knock down the swing mechanism, try to clamp the base of the gas cartridge in a vice and turn the swing mechanism.
4. After you have removed the swing mechanism, you need to knock the gas cartridge out of the crosspiece, for this, turn the crosspiece upside down with the rollers and, using a metal drift, knock the gas cartridge out of the conical base of the crosspiece with accurate blows. Make sure that you do not damage the front side of the chrome-plated cross-piece and the stiffening ribs of the plastic cross-piece.
5. The spider is disconnected! The difficult task is behind, now you need to assemble the chair, first screw the swing mechanism to the back seat, pay attention to the correspondence of the front side of the seat with the front side of the swing mechanism.
6. Now place the crosspiece with the wheels on the floor, remove the transport cap from the gas cartridge (you should see the button; attention! Pressing the gas cartridge button in your hands is dangerous), insert a new gas cartridge, make sure that the diameter of the gas cartridge matches the crosspiece, put on the protective cover and slide the seat body onto the rocking mechanism, if everything is in order, press your hands on the body of the chair, check all the elements again. You can sit on a chair and check the operation of the gas lift.

Attention! If you have a problem with the gas cartridge right after assembling a new seat, you may have come across a defective gas lift or rocking mechanism. But before contacting the dealer to replace parts, check if the button at the gas lift is not fixed by the lever from the swing mechanism.

Attention! If the gas lift does not respond to pressing the lever, check: - the swing mechanism or piastra is correctly attached, - the lever for pressing the gas lift button is not bent. In other cases, the replacement of the gas cartridge will be required.

All specialists in office and home furniture, in particular chairs, claim that the adjustment and position mechanism most often fails. Replacing the gas lift in an office chair is required if the foot does not respond to pressing and the chair is stuck in one position. It is certainly possible to repair it, but only a complete replacement is allowed, since the repair of certain parts will not bring results.

The plus is that any office chair can be repaired with your own hands, using photos and videos from the Internet.

Before you start repairing a gas lift, you should figure out what it is. In terms of internal and external similarity, it is compared with a shock absorber, only not disassembled.

If the seat does not rise and fall, then the internal parts are worn out and only a replacement will correct the situation.

It is imperative to know how to remove the gas lift from the chair so as not to damage the rest of the mountings and parts, the replacement of which will also lead to loss of money.

There are not many details in the chair, so the recovery process will not be stressful.

The computer chair itself rarely breaks down. This device lasts longer if you follow some rules:

1. You cannot sit on a chair from a jump.
2. Lubricate parts with a little oil.
3. Do not sit for two people, creating an edge.

The gas lift of the office chair holds the person throughout its entire service life.
