4.4.7 Mounting the torsion spring shaft
Fig. a and Fig. b , page A14. Slide the pre-as-
sembled right torsion spring shaft (35R) into the sole
plate (8R) and fasten it using the screw (S11).
Fig. c and Fig. d Slide the centre bearing (37) onto
the torsion spring shaft (35R). Observe the following:
NOTICE Two centre bearings (37) are required
for doors from BRB 3530 mm.
Mount one centre bearing (37) per side
and per torsion spring (35L/35R). Ensure
a sufficient distance to the torsion spring
shafts (35L/35R) again. The distance
should amount to at least 120 mm.
NOTICE The centre bearing (37) has to be
precisely aligned.
Ensure the precise alignment of the
centre bearing (37) to prevent an imbal-
ance and to guarantee the shaft running
smoothly.
• Ensure a sufficient distance to the torsion spring
shaft (35R) which should at least be 120 mm.
• Also consider to leave space for the shaft
coupling (38) and its installation.
• Put the centre bearings (37) in place with a slight
offset to the centre of the door in order to leave
space if a door drive will be installed.
• Choose a suitable reference point (upper edge of
angle frames 1R and 1L, garage ceiling) to
determine the position of the centre bearing.
Fig. e Screw the centre bearing in place by using the
screws (S8) and the plugs (S9).
Fig. f Slide the shaft coupling onto the shaft end of
the right torsion spring (35R).

shaft (35L) the same way you mounted the right.
Then centrally slide the shaft coupling (38) over both
shaft ends. Only fasten lightly in order to guarantee a
subsequent adjustment.
4.5 Mounting the door leaf
4.5.1 Premounting the bottom section
Fig. a , page A18. Pull the bottom seal (47) into the
bottom rail and adjust the length accordingly.
Fig. b Insert the rubber end plugs (45L/45R) on the
left and right each.
Fig. c Fig. d , page A19. Always remove the pro-
tection film on every door segment by carefully
carving into the protection film along the end cap,
then pull off the film.
Fig. e Fig. f Attach the logo (58) to the outside of
the bottom section (44), then fasten the bottom
grip (49) on the inside by means of the screws (S19).
When screwing, observe the permissible torque of
10 Nm.
These assembly, operation and maintenance instructions must be kept for the entire period of use!
Mount the left torsion spring
4.5.2 Mounting the bottom section
Fig. a , page A20. Clean the seals of the angle
frames (1L/1R) with a damp cloth. Position the bot-
tom section (44) in the door frame and secure it
against toppling over.
Fig. b Pull the track roller (56) out of the pre-as-
sembled track roller holder (61) of the external
hinge (48L/48R) and insert the track roller into the
track roller holder (61) on the other side.
Fig. c Mount one external hinge (48L/48R) each to
the top left and right of the bottom section (44).
Use the screws (S19) for assembly and observe the
permissible torque of 10 Nm.
Fig. d Pull the track roller (56) out of the pre-as-
sembled track roller holder (61) of the lower mount-
ing (57L/57R) and insert the track roller into the track
roller holder (61) on the other side.
Fig. e Fig. f Unreel the wire cable (104) from the
torsion spring shaft (35L/35R). Feed the wire
cable (104) behind the mounted track rollers (56) and
put it on the bolt of the mounting (57L/57R) along with
the cable eye and the plastic bushing (59). Secure
the wire cable (104) with the split pin (60).
Fig. g Fig. h Attach the lower mounting (57L/57R)
to the bottom section (44). To do so, tilt the mount-
ing (57L/57R) towards yourself and insert the roller
first into the rail of the door frame (1L/1R). Then tilt
the mounting (57L/57R) back into its final position.
Fig. i Use the screws (S19) for assembly and ob-
serve the permissible torque of 10 Nm.
4.5.3 Horizontally aligning the door leaf
Fig. a Fig. b , page A22. Wind the wire
cables (104) up by approx. a half-turn (prestressed)
so that they are under slight tension. By means of the
spirit level, check whether the bottom section (44) is
aligned horizontally. If required, adjust it at the torsion
spring shaft (35L/35R).
Fig. c Afterwards, tighten the shaft coupling (38).
4.5.4 Adjusting the track rollers
Re-adjust the track rollers every time you
insert another door segment. This allows you
to have a good insight on the distance
between the sliding strip of the frame and the
inserted door segment. In doing so, observe
the following settings for different door drive
types.
Fig. a , page A23. Loosen the screw (56a) for ad-
justing the track roller (56).
Fig. b Hand operation and ceiling pull: Adjust all
track rollers (56) in a way that the door segment's dis-
tance to the sliding strip is approx. 1.5 – 2 mm (pull
rolls in direction of the arrow).
