3.9 final checks
For optimal performance the door needs to operate
efficiently.
a) Manually move the door up and down, the door
should move freely without binding or sticking.
b) The maximum force required to move the door
should not exceed 20kg.
c) Lift the door to about halfway. When released, the
door should stay in place. Fig 3.9.1.
d) Check that the clearances in the vertical tracks as
per Fig 3.1.2 is also in the horizontal tracks.
e) If you find that the door is binding, open out the
horizontal tracks slightly to create the correct
tolerance.
f) Once satisfied that the operation of the door is as
near perfect as possible, check that all nuts and
bolts are tight.
g) Oil the springs full length to prevent noise and
reduce friction. INOX MX5 or similar oil rich lubricant
in a pressure spray can is acceptable. Fig 3.9.2
