Inspection instructions
Operation, service life and the easy running of the sectional door
depend decisively on all parts being mounted in accordance with
the installation instructions. If the door should nevertheless not
function perfectly, please check the following points:
33 Have the side angular frames, the frame panel and the pairs
of horizontal tracks been aligned exactly in the horizontal,
vertical and diagonal plane and have they been securely
mounted?
34 Have all screwed connections been tightened properly?
35 Have the transitions between the vertical tracks in the
angular frame and the 89° bends been adjusted? (cf. Point
16)?
36 Have the spring tightening straps been tightened to exactly
the same position on both sides? Check the extension
spring tension. Open the door halfway. The door must re-
main of its own accord in this position.
36a If the door closes noticeably, increase the extension
spring tension in accordance with Point 31.
36b If the door opens noticeably, reduce the extension
spring tension in accordance with Point 31.
37 Have the spring connectors at the back corner connection
brackets been inserted?
38 Rollers: can all the rollers be turned effortlessly by hand
when the door is closed (cf. Point 29)?
39 Have the top rollers been adjusted correctly? (cf. Point
29d/e)?
40 Have the second-to-bottom rollers been adjusted cor-
rectly? (cf. Point 29c)?
41 Are the distances between the roller axles and roller holders
identical when the door is half opened? (cf. Point 25)?
42 Do the double steel cables lie in their guides exactly and
without twisting?
43 In the case of a door operator: has the locking system been
dismounted?
