When to adjust windows
A window is usually a very heavily used element, so after some time even the best-quality windows need their hardware adjusted. You can do it yourself or call in a professional.
Noticeable draughts
Adjusting the sash compression against the frame improves the window’s seal.
The window does not close or is hard to open
A corrective adjustment of the sash position improves how it works.
Before summer and before winter
Seasonal adjustment: sash compression is increased for autumn and winter and reduced for spring and summer.
A new window in its first year
The sash can drop noticeably within the first year of use, so even new timber windows need adjusting.

Adjusting windows
The windows are fitted with Gretsch-Unitas tilt and turn hardware. Like any fitting in a building, every window is subject to normal wear, and the ease of operation and service life of the hardware depend on maintenance.
Modern timber windows have hardware that lets you adjust the position of the sash in three planes.

Summer and winter adjustment
Windows can be made tighter for autumn and winter and less tight for spring and summer by increasing or reducing the sash compression.

Hardware maintenance
At least once a year, two tasks are worth doing:
lubricate the moving parts and locking points and check that they work
tighten the screws holding the handle, carefully releasing the rose
The drops on the diagram are the lubrication points: the moving parts of the hardware and the locking points.
We recommend regularly checking the outer surface of the window and the glazing and repairing any damage promptly. The seal must not be painted or varnished.

Stepped tilt
The optional stepped tilt lets the sash be held in one of three tilt positions: with the sash tilted, pull it gently towards the frame and turn the handle downwards. The mechanism is fitted at the side or at the top, so it is worth checking both.
Timber entrance doors have three BAKA Protect 3D hinges, in which each part has a specific function.
The top and bottom hinges adjust side play and compression, and the middle hinge adjusts height and side play. All three adjustments are made with an SW 4 Allen key.

Which key do you need to adjust ABA Wiktorczyk windows?

Which key do you need to adjust entrance doors?
Timber entrance doors have BAKA Protect 3D hinges. Side play, height and compression are set with an SW 4 Allen key.

Side play can be adjusted by up to 3 mm in each direction (towards the lock or towards the hinges), height by up to 3 mm and compression by up to 4 mm.
When should windows be adjusted?
When you notice a draught, when the window does not close or is hard to open and close, and before summer and before winter. Even new windows need adjusting, because the sash can drop in the first year.
How do you set windows for summer and winter?
For autumn and winter the sash compression is increased, which improves the seal, and for spring and summer it is reduced.
How often should window hardware be maintained?
At least once a year: lubricate the moving parts and locking points and check that they work, and tighten the screws holding the handle, carefully releasing the rose.
