You are holders of windows furnished with top class hopper and casement hardware from Gretsch-Unitas.
Each window, similarly to any component of the building equipment, is subject to normal wear. Easiness, reliability and lifetime of window hardware substantially depend on correctness and frequency of maintenance jobs. It is why we recommend carrying out the following maintenance procedures at last once a year:
- lubricate all the moving parts and locking points and check their operability
- tighten the screws that fix the window handle (release gently the rosette)
Adjustment of window sashes
If necessary, the window manufacturer may provide the service adjustment of window sashes! We recommend signing the relevant service contract. When hardware malfunctions prevent from routine use of the window, it is necessary to call a competent serviceman.
Adjustment of clamping force for the window
Lateral adjustment of the sash – the spacing member.
Raising of the sash, adjustment of the clamping force. Lateral adjustment of the sash – the corner hinge.
Adjustment of the clamping force for sashes.
Option: gradual tilt. When the sash is tilted one has to slightly push the sash towards the jamb and then move the handle downwards. This makes it possible to set the sash to the desired tilting position: 1, 2 or 3.
The drawing shows the mechanism mounted at the side position. It is also possible to mount it at the top position.
