Spring fracture case of damage
Replacing the torsion spring shaft may only be car-
ried out by a competent person, see chapter 2.3 -
Personnel qualifications.
In case of a spring fracture, proceed as follows:
1. Fig.
a
, Page A26. Slowly push the door leaf in
its open end position. The pawl clicks into the
teeth of the locking wheel which prevents the
door leaf from sinking.
2. Fig.
b
By means of clamping jaws, secure the
door leaf in its open end position against sinking.
3. Fig.
c
Press the pawl (I.) in direction of the ar-
row. Also turn the spring fixed head (II.) in direc-
tion of the arrow so that the pawl releases the
locking wheel again.
4. Fig.
d
Use the R-pin (97) to fix the spring fixed
head on the sole plate. The R-pins (97) are loc-
ated on the left and right side in the upper holes
of the angle frame.

Carefully allow the door leaf to sink down
again.
6. Carefully relieve the intact spring from tension.
Hazardous tensioned springs!
WARNING
Springs are under high torque and can
release large forces when being ten-
sioned or when being relieved from ten-
sion.
•
Wear suitable personal protective
equipment when tensioning the
springs or when relieving them from
tension.

Replace the entire torsion spring
shaft (35R/35L). In doing so, also observe the
following chapters:
4.4.7 - Mounting the torsion spring shaft
4.6.1 - Tensioning the torsion springs
8. Check the door for further damaged parts and
replace them if necessary.
9. Activate the spring fracture detection function by
pulling the R-pin (97).

Maintenance / checks
7.1
Maintenace activities – operator
The following points must be checked and carried out
after the installation of the door and every 6 months:
•
Always grease the roller axes after
approx. 5000 door actuations. Clean horizontal
rail pairs.
•
Apply oil on the torsion springs.
•
Do not apply oil on the lock cylinder. In case it
does not run smoothly enough, treat with
graphite spray.
•
Ensure sufficient ventilation (drying) of the door
frame. Water drainage must also be ensured.
•
Protect the sectional door from caustic and
aggressive agents such as acids, lyes, thawing
salts etc. Only use mild household cleaning
agents.
•
Steel-filled sectional garage doors are coated
with polyester at the factory. Any paintwork on
site must be applied within 3 months from
delivery using 2C epoxy primer containing
solvents and, once hardened, standard paint.
•
Touch up the paint at intervals as required by
local environmental and atmospheric conditions.
7.1.1 Cleaning
We recommend wiping the door regularly with a soft,
damp cloth. If necessary, use a mild cleaning agent
or soap with lukewarm water. Avoid using any polish-
ing agents or abrasive or organic solvents/cleaning
agents. Before cleaning, flush the door and glazing
thoroughly with water to avoid scratches caused by
dust particles.
7.2
Maintenance activities – competent
person
The following maintenance activities may only be car-
ried out by a competent person, see chapter 2.3 -
Personnel qualifications.
•
Check the door in accordance with the test
instructions.
•
Check screws and clamping connections for tight
fit and retighten if necessary.
•
Check wearing parts (springs, wire ropes etc.)
and replace with original spare parts, if
necessary.
•
Make sure that the spring tension is correct. If it
is necessary to adjust the spring tension,
proceed in accordance with the assembly
instructions.
•
Replace the torsion spring shaft and wire ropes
after approx. 25,000 door actuations (open/close
movements).
This is equivalent to approx.:
Door actuations per day
0 - 5
6 - 10
11 - 20
Replace
every 14 years
every 7 years
every 3.5 years
