Inspection instructions
All parts must be assembled as described in the installation
instructions to assure the functional reliability, durability and
smooth operation of the sectional garage door. If the sectional
door still does not function properly, please check the following
points:
(22) Are the side angular frames, frame panel and horizontal
track pairs exactly aligned horizontally, vertically and
diagonally, and securely fastened?
(23) Are all screw connections tight?
Have the vertical ceiling mounts for the horizontal track pairs
(24)
been installed?
[1.30]
(25) Have the transitions between the vertical tracks in the

(26) Is the tension of the torsion springs the same on both sides?
Check the spring tension: Open the door halfway. The door
must hold in this position without help.
(26a) If the door sinks noticeably, increase the torsion
spring tension.
(26b) If the door moves up noticeably, reduce the torsion
spring tension. Has the sectional garage door leaf
been tensioned with the coupling and torsion spring
exactly as specified, and has the tension of the
second
accordingly?
Is the wound cable seated exactly in the drum guides? Are
(27)
there at least 2 turns of cable on the drum for safety reasons?
(28) Are the centre bearings aligned exactly to ensure smooth
shaft movement?
(29) Roller: Can all rollers be easily turned by hand when the
door is closed?
(30) Has the top roller been correctly adjusted?
(31) When the door is open, do all roller axes extend by the
same distance out of their holders?
(32) Doors with operators: Has the locking mechanism been
dismantled?
