Plastic windows - winter adjustment option. How to change plastic windows to winter position

When installing a plastic window, a specialist will immediately adjust them. Do they need to be further regulated? Why is this necessary? How to adjust windows for winter? How to adjust them for the summer? How to adjust in spring and autumn? What do experts advise and recommend about this? Let's try to answer the questions posed and understand the topic.

Why do you need to adjust plastic windows?

So that the sash does not touch any elements of the fittings when closing and opening or window frame.
To ensure that the sash fits tightly to the frame, and there were no drafts.
So that the window brings joy and satisfaction from use.
It is necessary to periodically adjust the valves so that you don’t have to pay for expensive window repairs in the event of a breakdown.
If the window begins to sag.

Step-by-step instructions for winter adjustments

IN winter time You can check the quality of installation of the plastic window. If you find a draft, you don’t need to immediately blame the installers. They set it according to daylight saving time. To eliminate a draft you need to adjust the clamp plastic windows.

Before starting work, you need to prepare:

Remove all debris and dust from joints and joints using a damp cloth. Dirt should not get on the mechanisms inside the window and hinge.
The surface of the fittings is cleaned with a brush with hard pile.
All dirt is removed from the rubbing mechanisms, as well as used lubricant.
If the seals are worn out, they need to be replaced.
Adjustment screw and the hinges are lubricated with silicone grease.

Let's move on to the adjustment:

The roller should be rotated so that the line drawn on it faces the direction of the room

Step-by-step instructions - for the summer

Before making adjustments, you must perform preparatory work described above.
Needed again before starting works to raise the roller.
Take a hexagon and turns to right side.
Roller needed install in place.
This operation is repeated with all the videos.
To add fresh air in summer time it is necessary to loosen the pressure on the window.
Take a hexagon and with its help the eccentrics are unscrewed.
You need to turn them to the right by a few millimeters.
You need to monitor the tightness of the pressure.

Take the hexagon and turn it to the right

Adjustment for autumn and spring

It is not necessary to make adjustments for spring or autumn, only if necessary. If this still needs to be done, then only the rollers need to be adjusted. They need to be screwed or unscrewed a little depending on the time of year outside the window. In the off-season, you can loosen the pins and put them in the appropriate mode.

The rollers need to be screwed or unscrewed a little depending on the time of year outside the window

Adjusting the sash pressure

This is done by adjusting the locking pins. Their number depends on the size of the window.
If the pin is round, then you will need a 4mm round wrench to work. They have a special slot for this key.
Initially, the pin is not centered, but is shifted either up or down.
To press the sash, you need to insert the key into the center of the pin and turn it left or right.
There is a small red dot on the top of the pin. If you turn the key to the right, the red dot will look inside the room, which means the doors will be pressed tightly.
If the point faces the street, then the shutters will be weakened.
If the toe is oval, then you will need an installation wrench to operate.
To press the doors firmly, you need to turn the pin perpendicular to the sash.
To reduce the pressure, you need to turn the claw to a vertical position. It should be parallel to the window sash.

It is necessary to adjust the window mode depending on the time of year very carefully. This work must be approached seriously and responsibly, because a person who is not experienced in this matter can break the window fittings and will have to call specialists and pay for repairs.

Mandatory periodic maintenance and adjustment of plastic windows for the winter are important measures during the operation of double-glazed windows. There is a small amount possible options breakdowns of window structures, the elimination of which is carried out in as soon as possible and without the involvement of specialists in this field. In this regard, it is necessary to clearly understand how to adjust and configure window fittings and how to use the configured elements correctly.

Elimination of cross-wind

The PVC window structure does not have additional doors for ventilation. In this regard, to perform the presented procedure, the locking flap should be moved to the appropriate position.

In case of drafts, tighten the hinges

During operation, there are frequent cases of drafts. This circumstance is caused, as a rule, by wear of the internal sealing rubber bands and improper maintenance of windows made of the presented material. Particular sensitivity of through wind manifests itself in the winter season, when streams of frosty air penetrate through the cracks between the frame and doors, leading to the formation of ice in defective places.

To identify the areas through which the cold enters, it is enough to hold a lit match along the perimeter of the entire PVC window. In places where the flame will fluctuate, it is worth immediately tightening the hinges and making spot repairs.

The procedure for eliminating drafts can be carried out using the following methods:

Adjustment of the trunnion (eccentric) - the element that rests on the response part of the sash. The features of this procedure include:
moving the pin of plastic windows winter and summer is done by rotating it using a hexagonal screwdriver in one direction or another (as an alternative to this tool, you can use ordinary pliers);
when adjusting the eccentric, its rotation should be performed with minor deviations (1.5-2 mm from the original state);
if the structure is overtightened, the trunnion must be loosened by turning the adjusting element in the opposite direction.
Clamping mechanism. Answering the question of how to adjust a plastic window for the winter using this method, you should refer to making adjustments to the position of the hinges of the tilt-and-turn mechanism. To do this, you need to switch the window door to the ventilated mode and press its top hinge to the frame. Due to the presence of a pressure plate part on the frame, by adjusting it, it is possible to achieve a reliable fit of the sash element to the frame.

Performing winter-summer adjustment

Adjusting the window for winter

Adjustment of plastic windows winter and summer can be carried out without the involvement of specialists, which will significantly save money family budget. When answering questions about how to adjust plastic windows, how to properly configure the control elements, how to transition windows to winter mode, you should refer to adjusting the trunnion by increasing or decreasing the pressure of the sash on the PVC window frame using a pressure plate.

In production, manufacturers initially install the eccentric in an average position, which provides a seemingly fragile connection between the window and the frame, but does not allow air flows from the street space into the house when closed.

The presented average adjustment of the trunnion is typical for the summer season, when precipitation does not enter the small gaps between the sealing rubber bands and the window structure.

Adjusting windows to the “winter” position

In advance of the first frost and the arrival of negative temperatures during the daytime, optimal contact between the sash and the frame should be ensured. At the same time, when answering the question of how to adjust plastic windows for the winter, you should remember that when the trunnion is tightened, the pressure on the intermediate sealing rubber bands increases. In the “winter” position, the position of the eccentric is slightly shifted to the right and pulled towards itself.

When performing this activity, the following features should be taken into account:

the distance from the roller part to the corresponding fittings must be minimum values(the proper position of the windows and the correctness of their assembly can be determined by the notch on the roller, which is directed towards the sealing rubber);
if windows are installed in the current calendar year, window adjustments are not required;
excessive compression of the seal by the action of the pin on it can lead to deformation of the rubber bands and the appearance of gaps between the windows and the frame part.

Adjusting windows to the “Summer” position

With the arrival of the warm season, when the optimal temperature regime, the windows should be converted to summer position. To implement this measure, you should pull the trunnion and move it slightly to the left. At the same time, it is necessary to monitor the mark on the roller element at the time of transfer.

For ideal window adjustment, the position of the pin after displacement should be directed towards the window handle.

Having completed the described action, the pressure on the sealing rubber is reduced, resulting in optimal circulation and air flow into the room. For details of winter-summer adjustment, see this video:

Adjusting the roller positions should be done for PVC windows of all types and modifications. This circumstance is due to the frequency of use of window structures in winter and summer. Due to the fact that in the summer ventilation window opens with greater frequency, it is necessary to ensure favorable conditions for the functioning of the sealing gum (it should not experience excessive loads and changes in its structure).

Elimination of improper operation of handles

If there is a need to replace an old handle, install restrictive elements, or fix a loose handle, you should not immediately call specialists to your home. Adjusting plastic windows and balcony doors with your own hands can be done in a matter of minutes if you know the features of their functioning.

Installing a new handle

This activity is not always caused by a broken handle. If children live in the house, they can easily open the doors and climb out. In this regard, it is advisable to install these fittings with special limiters that prevent the free opening of windows. For details on installing the handle, watch this video:

To perform the replacement, rotate the handle to the open position, unscrew the protective plastic to the side and remove the screws using a screwdriver.

The new handle is installed by performing the same steps in the opposite direction.

What to do if the handle is jammed

It is not uncommon for the handle to jam when turning the handle. Don’t immediately panic about replacing this piece of hardware. In most cases, jamming is caused by blocking of the element to prevent damage to the entire window system.

How to turn the handle correctly

Before performing any actions, you should determine the markings of the fittings. As a rule, its name is displayed on the closures of the product.

The procedure for removing the handle from a jammed state into various types accessories:

“AUBI” - we find a spring metal plate and press it against the seal, after which we try to turn the handle to its original position (when performing this activity, all work is carried out in a strictly vertical state, any deviations from the norm can lead to the operation of the upper lock);
“ROTO”, “GU”, etc. - find the metal tongue (as a rule, it is located slightly below the handle) and press on it. As a result, it should be installed in a position parallel to the rubber seal, and the handle should turn freely.

During prolonged use of the windows, as a result of repeated temperature influences, the tongue may not reach the mating part, and the rotation of the handle will be blocked. In this case, you should move the response element towards the tongue, unscrewing the retaining screws and placing a piece of durable material (plastic scraps, a small washer, etc.).

Conclusion

Window adjustment rules

In conclusion, I would like to note that timely, correct adjustment of PVC windows is the key to their reliable and high-quality functioning over a significant period of time. Along with the listed features of the elements and the procedure for switching to summer and winter modes, lubrication should be performed in advance metal products window structure using a special penetrating lubricant or machine oil. Taking into account all the listed features, the developer, through correctly adjusted elements of window structures, will provide his home with the maximum comfortable conditions for existence.

If your apartment or private house has plastic windows, be sure to familiarize yourself with the concept of winter-summer adjustment. This knowledge will help you control air exchange and maintain optimal microclimate in room. Many opponents of plastic windows insist that these products “do not breathe” and prevent natural circulation air, resulting in increased humidity in the apartment, appears.

If you do not plan to leave the sash in ventilation mode in winter, this will help you normal adjustment. In fact, the tight fit of the window sash to the frame depends not only on the rubber seals, but also on the fittings. Let's consider design features fittings responsible for adjusting the plastic window in winter and summer modes.

Adjustment fittings for winter-summer modes

When the sash is open, on the vertical end you can notice metal linings in the external (visible) and internal (hidden) mechanisms. The external mechanism is presented in the form of an eccentric; experts often call it a “trunnion”.

Externally, the trunnion can be of different configurations:

in the form of a roller with a notch;
shaped like an oval handle with a smooth surface;
in the shape of a small oval handle with a short and long notch;
shaped like a bolt head internal section under the hexagon.

Adjustment can be made either manually or with a regular hex key with a diameter of 4 mm. In any case, you can do this yourself without calling a specialist. Self-manual adjustment of the roller journal has one important nuance: to rotate the eccentric and set it to the desired position, you need to pull it slightly by the cap with your fingers.

Setting the desired mode

To install plastic windows or balcony doors in winter mode, you must perform the following steps:

determine the location of the trunnions;
turn the trunnion so that the long notch is turned towards the sash seal;
Check the tight fit of the sash to the window frame.

If you have a model of fittings with a smooth oval trunnion without notches, then you should turn it from a vertical position to a horizontal one, then the level of pressure will be maximum.

For transferring plastic windows and balcony doors in the “summer” mode, you need to use the same tools or with your own hands to turn the trunnion head so that it is positioned vertically, or the notch on the eccentric is directed in the direction opposite to the seal. Adjustment in the off-season - autumn and spring involves a vertical position of the oval pin or notch.

Important nuances of winter-summer adjustment

In order for the pressing density of the sash to be uniform, it is necessary to change the position on all trunnions located along the end of the sash. Their number depends on the height of the structure; there are three eccentrics on a standard window. U modern models The fittings responsible for the tightness of the sash can be located at the ends of the sash along the entire perimeter of the window. Take the time to check their presence at the top, bottom, and also on the back bar. The adjustment should be the same at all points.

It is necessary to adjust the pressure in advance, before the onset of the first frosts. If you miss the moment, the sash may simply freeze to the frame. If there is a strong difference in temperature in the room and outside the window, condensation can form outside, which instantly turns into ice, firmly holding the seal and the plastic frame together.

If the trunnion turns tightly, it is necessary to lubricate it with machine oil using a syringe. swivel mechanism and wait a few minutes. For prevention, this procedure is recommended to be carried out every time the window is switched to winter or summer mode.

In the off-season, it is recommended to install the trunnion vertically, that is, in standard mode with medium sash pressure. The same adjustment is recommended in regions with warm winter, where the air temperature does not fall below 5°C.

Before changing the season, it is recommended not only to change the clamping force, but also to carry out preventive maintenance on the seals. In summer, under the influence high temperatures, the rubber seal may lose moisture, become cracked and deformed. This will lead to wind, dust and wet precipitation entering the room. To prevent such a problem from happening, the seal must be lubricated with a spray containing a silicone compound. Thanks to this, the rubber will remain elastic, will not dry out and will not freeze to the frame.

When switching plastic windows to the “winter” mode, the window handle will close a little harder. There is no need to worry about this and call a specialist to debug the fittings. After setting the trunnion to the “winter” position, the pressure bar moves closer to the sash, and this is why the handle moves tightly, but this is not a malfunction.

If your apartment has new plastic windows, in which the seal is too soft, it is not recommended to use the “winter” mode. The thing is that the seal, which has not been used before, very quickly takes on the shape given to it. If you turn the eccentric to winter mode and tightly close the window sash all winter, in the summer the seal will be compressed and will no longer be able to take its original shape.

To ensure that your windows do not lose functionality, we advise you to read our article “”, in which you will find information about options for adjusting windows, adjusting sashes, fittings, and the basic rules for self-adjustment.

Adjusting windows for winter is very important aspect. But often people don’t know about this or simply forget. If you do not maintain windows, even the most expensive ones can break or lose their properties. Windows must be handled with care, otherwise consequences such as drafts, cold and noise coming from the street may occur.

This manipulation should be carried out before the onset of frost, while the air temperature outside is above zero.

Why is it necessary?

Probably many people know that plastic windows have two modes: summer and winter. Each of these modes performs its own important role. When purchasing and installing windows, you should be instructed on how to properly set up and use plastic windows. Thanks to this, you can avoid many problems. However, most often no one knows how to configure it correctly, so they use the services of specialists. But to customize the windows, you won’t need much effort, because there is nothing complicated about it.

The initial adjustment is made immediately after installing the window. Of course, this makes life easier, but it will not help you in the future when the seasons change.

Many craftsmen say that adjustment is very important for windows; this is the main test of how the windows will behave in cold weather. By adjusting the windows, the temperature in your room will remain within normal limits, you will be able to avoid drafts and significantly improve the tightness of the windows. If you neglect the adjustment or do it incorrectly, this can cause excessive humidity, and in severe frosts, frost can form on the windows. If your window is not the first year old, then the tightness of the window is already much lower than at the beginning of its operation; there are quite a few reasons for this problem.

To avoid unexpected damage, windows should be adjusted before each change of season. If you don't change the modes from summer to winter, you will allow cold air to penetrate into your home. As a result, the air temperature in the house decreases significantly and more energy is spent to maintain heat. The first window adjustment should be made when the window is initially installed. Try to also technical inspections at least once every 2 years. Often during inspections, specialists find any deviations in the design. The wizard will help you figure out this problem.

When adjusting structures, do not forget that weak pressure corresponds to the summer season, and strong pressure corresponds to the winter season.

Adjust yourself PVC double glazing making your own for the winter is not at all difficult. Our instructions will help you.

Tools

To adjust the windows you may need special tools. Try to stock up on tools such as pliers, hex keys, Phillips and flathead screwdrivers, and it's a good idea to have a set of screwdriver bits on hand.

To lubricate the structure, you can use ordinary machine oil or a special spray.

Identifying areas that need adjustment

In order to determine the places that need to be adjusted, you first need to find out whether the sash pressure needs to be adjusted. To do this, you need to set the position of the trunnions, which are located near the handle, on the edge of the window. Determine the pressure using dots or small stripes that are located on round section trunnions If the stripes face top position, then this means that on this moment The window clamp is in the middle or normal position. Usually this is the position that the specialist set for you when installing the window.

If you see that the stripes look inside the room, then this indicates that the design is currently set to winter season. And if the stripes look in the opposite direction, then, accordingly, for the summer season. In addition to the above, it would be useful to check the frame for sagging. Windows that were installed a long time ago are more likely to sag.

The sagging of the frame (sash) can be determined even by sound. When the sash sags, it rubs against the bottom of the frame, of course, this is accompanied by a specific sound.

Common Problems

The most common problems with plastic windows are:

condensate;
mold;
depressurization;
breakdown of fittings;
freezing in winter and other problems.

Condensation and mold– very unpleasant aspects plastic structures. In principle, the very presence of condensation is the norm, but there should be very little of it, and it is allowed only at the edges. If the window sweats completely, it is most likely due to high humidity indoors or due to a large temperature difference (outdoors and indoors).

The most economical and, of course, simplest solution is simple ventilation several times a day for 10-15 minutes.

But you can also install a special shutter on the window, which allows micro-ventilation. However, this service costs little money. Can be done indoors ventilation system. However, this is not cheap, and it will take a lot of effort.

Mold- This is a consequence of condensation. The cause of mold can be improperly made slopes. They can be plastered or made of plasterboard. The problem with plastered slopes is that they quickly freeze, which leads to the development of fungus. Slopes finished with plasterboard are not such a bad option, especially if they are insulated mineral wool. In this case they have excellent thermal insulation properties. But it is worth considering that such slopes can be made in rooms with low humidity.

Perfect option- This plastic slopes. They are easy to clean, do not need to be painted and, when insulated with mineral wool, retain heat well.

If the rubber band (seal) deteriorates, this may cause poor sealing. The easiest way is to replace the rubber band. However, remember that the elastic band will last you longer if proper care. The seal should be lubricated with silicone grease twice a year. Dust and dirt can accumulate there over time, causing the elastic to lose elasticity and crack. To avoid this, simply clean the rubber from dust and dirt before lubricating it. Do this at least twice a year.

Another common problem is hardware failure. This can be caused by dirt, dust and improper care. The first sign may be a clicking sound when turning the handle. Within a year the mechanism will most likely be broken. To extend the life of your window, lubricate and clean it at least 2 times a year.

Peculiarities

Before working with a window in the winter, you first need to set the value to neutral (standard) and check for the fact that the window is blowing. It is not recommended to press the rubber immediately after installing the window, as they can shrink and become deformed in a new state.

If you have a high-quality seal, then most often they give a guarantee, but this is subject to proper care. If you immediately set the pressure to strong, then it will quickly become unusable, and as a result, when the next winter comes, you will find that it is blowing from the windows even when switching modes from summer to winter, and the rubber has dried out and is all cracked. In this case, the seal should be replaced.

There are cases that even after adjusting the windows to the correct mode, in winter there is still a draft from the window, and even replacing new insulation didn't help. This usually happens if the house “sits”, then the window also sags. When you turn the window handle, the trunnion should go behind the plate and press firmly against the window. If this does not happen, then the window settings should be different.

How to install?

Before starting work, you need to find out which of the journals do not reach the plate. To do this, inspect the window sash and remember all the protrusions. After this you need to close the window.
Further grab the frame where the trunnions are installed, and pull it towards you. If the pin goes behind the protrusions, then the window will be immovable; if it doesn’t go, then, accordingly, the window can be moved. Thus, check all the places where there are trunnions and determine which places do not press tightly. Determine in which direction you need to move the sash. This can be done by adjusting the top and bottom loops.
If the window does not close well at the bottom, then you need to adjust the lower hinge. At the very bottom of the hinge there is an adjustment hole; it can be for a hex key or for an asterisk. To adjust, turn the key clockwise or counterclockwise. Accordingly, as it moves, the window moves closer to the hinge, and against it, it moves away. If you unscrew everything all the way, but there are no changes, return everything to its original position, most likely the matter is different.

There is another adjustment screw at the bottom of the hinge, but to get to it, you need to put the window on for ventilation and remove the protective cap. There will be no problems with removal; it is done very easily. After this, you will see a recess, insert the hexagon there and twist it clockwise or counterclockwise. When turned clockwise, the sash rises, and when turned counterclockwise, it lowers.
If this problem occurs at the top of the window, open it 90 degrees. There is also a hinge at the top of the window, but it is not the same in design as the bottom. But there is also a hole for a hex screwdriver. Next, make adjustments by turning the key to the right side. However, do not forget that you need to leave a distance of just a few centimeters between the sash and the hinge. This is necessary so that the tilt and turn mechanism has the opportunity to go there. Every time you turn the key, check how your window closes and opens.

Typically, adjusting the pressure means changing the mode for different seasons. In winter the pressure needs to be strengthened, and in summer it needs to be loosened.

First, make sure that you really need the adjustment. The easiest way is to hold about closed window have a match or lighter near the door. The flame will show whether the window needs adjustment, whether it is blowing out of it or not. Open the window and look closely at inner part doors There you will see three pins, they are the ones that regulate the window pressure. Using a hex screwdriver you can adjust the window.

Reading time ≈ 8 minutes

Modern plastic windows are installed everywhere, because they are superior in many respects wooden crafts. However, for full operation, adjustment of the position of the winter-summer plastic windows is required, which can be done independently in accordance with the instructions.

Why adjustment is required

You need to set one or another window mode according to the season. Due to rising and falling temperatures, windows need to be closed more or less tightly. Thus, it is possible to improve the flow of fresh air into the room in the summer and reduce heat loss in the winter. If the PVC window is always in the “winter” position, then sealing rubber Due to strong and prolonged pressure it will become unusable.

If you leave the window into winter with weak pressure, then drafts and high heat loss will occur inside the room. Often, when installing a window, the adjustment is set to the middle position, which corresponds to the “spring-autumn” mode.

When the season changes, it is advisable to make adjustments accordingly.

When to adjust

Setting the required position is required in several cases:

there is a strong draft through the frame;
the window closes and opens poorly;
the sashes sag;
the window fogs up when high humidity in room.

It is worth considering that some manufacturers (usually in the budget segment), in order to save money, install components that do not allow adjustment.

Varieties of adjusting elements

The force with which the opening part of the window leans against the frame is adjusted by special elements called trunnions. They are located on the side parts and on top of the sashes.

The quantity, appearance and location of these elements may differ both from the cost of the windows and from the manufacturer. The most common are:

PVC window adjustment sequence

To adjust plastic windows with your own hands and set the “winter-summer” mode, you need to familiarize yourself with step by step actions this process.

Preparing tools

To carry out adjustment work you will need the following list of tools:

hex wrench;
a set of nozzles in the form of stars;
minus and Phillips screwdrivers;
pliers.

Preparatory activities

Selecting the desired window mode is a matter of minutes, which every owner can do. However, first the windows should be prepared for use during the cold period. To do this, perform the following steps:

Sash clamp

Let's figure out how to switch plastic windows to the winter position:

The eccentrics rotate 180°: from the initial position 90° to the right and left, which corresponds to the “winter-summer” mode.

Top loop

Adjustment of hinges is resorted to in the event of a loose or uneven fit of the opening part of the window to the frame. So, to lean more top corner doors with the ability to rotate and tilt to the frame, you will need to tighten the screw with scissors.

If the sash sag and touches the impost, by changing its position you can get rid of the snag. The screw itself is located in a hinge, and to access it you will need to open a window.

Rotating the key clockwise ensures the lifting of the lower opposite corner of the sash, in reverse side- its lowering. During the adjustment work, you need to ensure that the trunnions do not rest against the strike plate. If the desired result cannot be achieved, you will need to tighten the screw on the scissors, for which the sash is opened so that it is held only by the lower hinge.

One of the plates has a bolt with a hex key. By turning it clockwise, more pressure is achieved on the opening part of the window against the frame. Reverse rotation will weaken the fit of the corner to the frame.

Bottom loop

The hinge at the bottom has 2 adjustment screws. One of them allows you to set the sash horizontally, i.e. raise or lower its upper opposite corner.

The second adjustment is at the top of the hinge. To get to the adjusting element, you will need to open and tilt the sash, and then remove the plastic lining. By tightening the screw, the sash can be lifted and, accordingly, vice versa.

If at horizontal adjustment If it was not possible to get rid of the lower corner of the sash getting caught on the profile, then by raising the opening part this problem can be eliminated.

You can learn more about adjusting plastic windows for “winter-summer” with your own hands from the video.

Setting up windows from different manufacturers

Each brand that produces PVC windows has its own characteristics, and adjustment is no exception:

Possible problems

When using PVC windows or carrying out adjustments, it may turn out that the fittings do not function properly. The reasons may be different, so some of them are worth dwelling on in more detail.

Loose handle

Most often, the handle begins to dangle due to loosening of the fasteners. The nuance is eliminated by displacing the plastic cover and tightening the handle fasteners with a Phillips screwdriver. As a rule, this is enough for the fittings to fit snugly against the window.

Sticky handle

Possible reasons for such a malfunction are:

Locked handle

If the handle is blocked, do not rush to change it. Typically this problem is caused by a malfunctioning locking mechanism that prevents the sash from changing state when it is open. You will need to turn the lever responsible for the lock so that the handle has free movement.

Broken handle

If the handle is broken, then the only solution to the problem is to replace the part. This is done quite simply: just turn the cover and unscrew the two screws, and then remove the handle. Installation of the new part is carried out in the reverse order.

Checking the window tightness

After the adjustment work, a sheet of paper is placed between the opening part and the frame and the sash is closed. Then they pull the leaf, controlling its tension. If the paper comes out easily, you need to adjust the opening part towards the window.

You can also use a lighter. If the flame deviates from the vertical, this will indicate insufficient tightness.
