Plastic windows, even the highest quality, require periodic adjustment and repair. In the process of operation, mechanisms are wearing disabilities. Adjusting the fittings of the plastic window can be performed with their own hands, if you first get acquainted with the recommendations set forth in the article.

The most common windows faults

List of faults that can be eliminated independently:

• when closing the sash, its bottom edge or side face hits the frame profile;
• between the sash and the frame - a big gap;
• erased the edge of the locking slats;
• the shut-off mechanism in the open position of the sash, while the handle is in the "closed" position;
• the window cannot be discovered, the knob is jammed;
• the handle failed;
• for turning handle, a significant effort is necessary.

To adjust the plastic window, you must have a tool from the following list at your disposal:

• key hexagon size 4 mm;
• figure and flat screwdriver;
• pliers;
• set of sprocket keys.

General information about the adjustment of the clamping efforts of windows

In order for the sash to take the right position, it is necessary to adjust it vertically, horizontally and relative to its axis. In addition, it is necessary to adjust the clamping efforts of the sash to be preserved with tightness in normal fittings.

There are three knots for adjusting the sash:

• top corner on the side of the loop and "scissors" (responsible for the pressure of the upper part and for the deviation to the right and left);
• the lower angle on the side of the loop (responsible for pressing the lower part, for the orientation of the sash vertically and for its deviation to the right-left);
• eccentrics located in the end of the window profile, above the handle (responsible for clamping the handle side).

Eccentric - Detail of the shut-off mechanism responsible for the density of the clamping

Adjustment comes down to rotating adjusting screws with a hex key or "asterisk" in a specific order.

Note: Scissors are called a movable part located above the upper loop. It is responsible for the work of the folding mechanism and keeps the sash in the regimen.

Technology adjustment of clamping efforts of sash depending on the type of malfunction

Consider typical faults of plastic windows and ways to eliminate them.

Adjustment of the deflection of the vertical sash

In the event that the sash is lowered too low or on the contrary - overly raised, its lower or top edge will match the frame profile. In this case, the procedure for the adjustment will be as follows.

Adjusting screw top loop

1. Opening the window, scroll the screw located in the end of the profile (at the top) clockwise. Use the hex key.
2. Close the window and remove the decorative lining from the bottom loop.
3. Scroll through the bottom loop of the hexagon also clockwise.
4. Closing and opening the sash, check the correctness of its position.
5. Tightening or relaxing the screws, we achieve the optimal position of the sash.

Adjustment of the sash in the height of the lower screw

Adjusting the deflection of the sash to the right or left

With this malfunction, the window sash will touch the frame from the handle side. It is necessary to reject the sash towards the loops. To get the desired effect, do the following.

1. In the event that the side face of the sash concerns the frame profile at the bottom, it is required to shift the opening part of the window towards the bottom loop. To do this, turn the screw clockwise, located on the bottom side of the loop.
2. To adjust the sash, taking the frame with the entire side face, it is necessary to shift the entire sash towards the loops. For this, in addition to the bottom loop screw, the screw of the top loop is required.

Elimination of deflection of the sash to the right

If worn shut-off stripes

To establish the degree of wear of the shut-off slats, it is necessary to inspect, opening the window. They are installed on each side of the window, besides the one where the loops. The wear of one bar indicates that the sash is shifted and incorrectly included in the frame. To eliminate the fault you need to do the following.

1. With an open sash, remove decorative plastic lining with both loops and weaken the screws with a hexagon (4 mm).
2. Adjusting the upper half of the sash to normal position (eliminate the deviation to the right or left).
3. Lower screw set the sash to normal vertical position.
4. Check the adjustment correctly, opening several times and closing the window. If necessary, perform adjustment.

Important: Decorative plastic lining should be removed carefully. They are made of fragile material of a small thickness. Find the replacement will be difficult.

Elimination of a loose clamping

Adjusting the clamping forces of the sash is made using eccentrics located on the end plane of the sash side of the handle. Eccentrics are cylindrical or oval parts, which are engaged in engagement with the response part of the locking mechanism.

Tool for adjusting the clamping efforts of sash - pliers: they should be checked for eccentric in one direction or another. At the same time adhere to the following rules.

Adjusting the eccentric pliers

1. Setting the clamping forces of the sash is performed depending on the season: adjustment of the sash for the winter period provides strong pressed, on the summer - weak.
2. If you need to adjust the pressing of the opening part on the loop side, you must tighten the screw located on the bottom loop (in the lower, front of it).
3. The clamp of the swivel flap is also adjusted by rotating clockwise the screw located above the upper loop, on the "scissors". To do this, with an open flap, by pressing the block, turn the handle to the folding position. Weaken clam by turning the screw counterclockwise.

IMPORTANT: The adjustment of the TPF in some cases can be performed by special keys.

In the event that the optimal clamp can only be installed only by the "Responding" displacement, apply the key as an asterisk. Weakening the fastening screws, the "response" shift towards the room or towards the street. It should be borne in mind: "Reliefs" can be installed both from the side of the handle and from the loop.

Options for adjusting the clamping efforts of the sash are shown in the figure.

If the knob is jammed

The design of the shut-off mechanism prevents the rotation of the handle with the open window. Randomly rotate the handle do not allow the blocks installed in the end of the profile. The junction handle can be unlocked by pressing the pre-blocker the book.

The handle cannot be rotated after closing the window: the reason for this is the incorrect operation of the block, which is not in engaging with the response part. Change the malfunction in the following ways.

1. Turning into a few revolutions of the screw, located under the bottom loop, shift the sash towards the "Promotion" of the block.
2. Close the "Protection" of the blocker with a thin tin, for which it is pre-slightly weaken the mount.

Tip: In order for the plastic window to be sealed, it is necessary to inspect the rubber seals and to change them in a timely manner if they were unusable.

Replacing a broken knob

To install a new one in the place of the broken handle, it is necessary to open the decorative lining of the plastic, under which the mounting screws are located. The pad is shifted by turning around its axis. After screwing the screws, dismantle the handle failed and install a new one in the same position. Finally, screw the screws and close the lining.

Remove the fastening screws to replace the handle

Adjusting the knob

In order for the handle to rotate not tight, the felting parts of the accessories must be periodically lubricated. Used for this aerosol, which includes machine oil. The recommended frequency of such a procedure is once a year.
