Only use mild, ph-neutral cleaning agents in diluted form for cleaning!
Never use sharp objects, scouring agents or aggressive cleaning agents (e.g. cleaning agents containing vinegar or acid), as these can attack the corrosion protection of the fittings! When cleaning, make sure that no water runs into the fitting. After cleaning, dry the hardware thoroughly and lightly oil the surface with an acid- and resin-free oil by wiping it with an oil-soaked cloth.
Your windows/window doors are equipped with a high-quality SIEGENIA fitting. In order to maintain its smooth running and perfect function for as long as possible, we recommend that you carry out the maintenance and inspection work described below at regular intervals (at least once a year or more frequently, or every six months in school and hotel buildings, near the sea or in areas where drifting sand is to be expected).
Grease or oil all moving hardware parts and all locking points. Use only acid- and resin-free oil or grease for this purpose. For the moving parts in the window sash, a spray grease is advantageous, which you spray into each opening of the fitting. Then move the hardware several times to the intended switching positions until the grease is distributed. Wipe off excess oil/grease from the window frame. Then grease the striking plates in the window frame with a stiffer grease (consistency class 2 according to DIN 51818) at the points where the locking pin engages in the striking plate. Our maintenance grease, which you can order from SIEGENIA under the material number ZXSXO 120-093010, is particularly suitable for this purpose.
