A Guidance on Hardware Maintenance
Regular maintenance of mechanical components will reduce wear and tear
and prolong the serviceable life. These recommendations assume that the
window / door has been made and installed to a standard not less than
that set out in the appropriate standard / code of practice and that all
operations function correctly.
In order to maintain correct cavity dimension of weatherseal compression,
adjustment is provided within most hardware available. Twice yearly
- Spring and autumn recommended.
Handle and other items which are visible from inside or outside when
the sash is closed, should be cleaned with a mild solution of warm soapy
water, applied with a soft cloth. Dry thoroughly afterwards.
Parts exposed when the window / door is open, including strikers, should
be wiped down to remove all residues of old lubricant and grime. Sealing
cams and strikers should be given a minute smear of petroleum jelly.
Sliding bars and face plate of drive gear should have silicone maintenance
CAUTION: Care must be taken not to damage the
surfaces of hardware. Abrasive cleaning agent and lubricants containing
corrosive substances must be avoided.
