In General:
Regular maintenance of mechanical components will reduce wear and tear and prolong 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/code of practice and that all operations function correctly.

 

Frequency:
it recommends twice yearly (Spring and Autumn) maintenance of window and door hardware.

Adjustment:
In order to maintain correct cavity dimensions or weatherseal compression, adjustment is provided within most hardware available.

 

Friction Stays � Twice Yearly Maintenance:
All friction stays with sliding shoes, which travel along a track, must be kept clear of dirt, debris and obstructions at all times. Use a soft, damp cloth with a mild solution of warm soapy water to clean the friction stay, then dry thoroughly afterwards. For optimum performance lubricate all pivot points with light (low viscosity) engineering oil.

 

Window & Door Handles � Twice Yearly Maintenance:
Window handles can often be cleaned with a soft, dry cloth. If further cleaning is required use a mild solution of warm, soapy water on a soft cloth and dry thoroughly afterwards.

 

Shootbolt Locking Mechanisms � Twice Yearly Maintenance:
Shootbolt locking mechanisms and strikers should be wiped down with a soft cloth, and a smear of petroleum jelly should be applied to mushroom cams and strikers. Silicone spray (for example, Mila Maintenance Spray SM1-11) should be applied to the shootbolt extensions and the faceplate of the drive gear.

 

Caution:
To prolong the serviceable life of the window, care must be taken not to scratch or damage the surfaces of the window hardware during maintenance/cleaning. Always use soft cloths for cleaning - do not use wire wool or scouring agents. Never use solvent based lubricants (such as WD40) or abrasive cleaning agents. All residues of old lubricants should be removed prior to maintenance.

 

Remedial Maintenance:
Remedial maintenance resulting from mechanical or operational difficulties should only be undertaken by an approved maintenance engineer. Unauthorized remedial maintenance may invalidate guarantees. A check on the tightness and security of all fixing screws by an approved engineer is recommended every 5 years.
