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:
MILA recommend 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 a 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. Unauthorised
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 |
