A special mechanism — window fittings - is responsible for pressing the sash to the frame, as well as for opening and closing the window in various modes. The elements that are responsible for setting up the work of the fittings make it possible to adjust it so that the sash can be easily opened and closed regardless of weight, dimensions and operating conditions.
However, over time, even the most reliable hardware settings can get lost. Therefore, periodically the fittings require adjustment — otherwise problems may arise.:
In all the cases described, it is necessary to adjust the plastic window. At the same time, with the help of special tools, the optimal settings of the mechanism should be restored so that the sash moves freely again.
The window mechanism is equipped with several elements that are designed to adjust the position of the sash. To understand where they are located, it is worth finding on the Internet a diagram of the accessories installed in you and studying the manufacturer's recommendations for adjustment.
In addition, with self-adjustment, you will need:
It is also worth stocking up with a duster and grease for processing the mechanism after adjustment.
One of the simplest problems that can be solved in just a couple of minutes is a loose handle. In 90% of cases, it's about fixing screws. To solve the problem:
That's all — the handle should hold tight and not wobble.
Pay attention! A crack in the base of the handle is a reason for its replacement: repair or adjustment in this case is impossible.
Insufficiently effective clamping is the reason for the appearance of drafts and blowing around the perimeter of the window. But the opposite situation also occurs — due to strong or uneven clamping, difficulties arise with closing the window or the seal is severely deformed.
If the problem is related to a draft, it is worth finding a place where the clamp has weakened. The problem is localized with a candle or lighter — a stream of cold air will deflect the flame.
To adjust the clamp, locking pins are used, which can be oval or round (with an eccentric). The trunnion is rotated with pliers or a hex key. To adjust the optimal pressure:
Advice! After adjustment, we open and close the sash several times. This is necessary to check the functionality of the fittings — there is a risk of "overstretching" or "understretching". Also, do not forget that an excessively strong pressure harms the sealer — the elastic contour is deformed and requires replacement much earlier.
In addition, the clamp is also adjustable with the help of screws on hinges. For this:
As in the previous case, be sure to check whether we have adjusted the clamp correctly. To do this, we close the sash and evaluate whether the fittings work easily and whether the draft has disappeared.

The displacement of the sash and its misalignment can be eliminated with the help of adjusting screws. They are located on the hinges of a plastic window and are equipped with slots for a hex key. The sash can warp under its own weight, with intensive operation of the window or with improper installation of the hinges themselves. But in any case, when it is skewed, you need to adjust the position of the part.
When adjusting, we are guided by the following rules:
You can adjust the vertical position of the sash using the bottom loop. Insert the hex key into the socket screw, then:
Important! Such manipulation can raise the lower corner of the sash, which is closer to the hinge part, by 1-3 mm. This is enough to solve most of the problems.
For horizontal adjustment of the sash, screws are used on two hinges at once — the upper and lower:
Important! Access to the adjusting screw on the upper hinge can only be obtained when the sash is open.
In the presence of a scheme and minimal skills, the metal-plastic window can really be adjusted with your own hands, eliminating blowing and problems with closing. But in difficult cases, it is worth contacting a master for the repair and adjustment of plastic windows. He will not only cope with the task faster, but will also be able to perform more complex manipulations — for example, he will eliminate a strong distortion of the sash by adjusting the double-glazed window.
In any case, the correct adjustment of the plastic window is the key to its stable operation and your comfort.
