General Maintenance
Door controls
In research, Allegion has identified
that 95% of all problems associated
with overhead door closers can
be attributed directly to errors in
installation rather than problems with
the door closer itself. If the door is not
closing properly into the frame you
should first disconnect the door closer
(disconnect the arm(s)) and determine
that there is not an underlying problem
with the door, frame or any smoke /
draft seals that might be fitted.
PLEASE NOTE:
The power of the door closer should
not be used to overcome problems
associated with the door or other
items of hardware fitted to it.
Under no circumstances should the
closer body be dismantled.
Visual checks
Primarily making a visual check on the product and surrounding
door/frame looking for wear, damage, and general condition.
Functional checks
Consists of checking that the product operates properly ensuring
the door can fully close without any binding or undue force
required. Check that any seals or weatherstripping do not inhibit
correct operation of the door
Check fixings
Fixings need to be checked regularly and tightened when
necessary. Check that no projection of fixings prevents the door
from swinging freely.
Lubricating
Some products will benefit from periodic lubrication using a light
machine oil or as instructed.
Cleaning
Build up of grease, dust and harmful chemicals should be removed
to prevent corrosion and maintain the product finish.
Types of maintenance
Much of the routine maintenance recommended consists of a combination of
visual and mechanical checks, cleaning and lubrication. Look out for the icons
opposite which provide a ‘quick glance’ reminder of the maintenance required.
