IMPORTANT: There is much strain on tensioned springs; proceed
carefully at all times, especially when performing corrective
maintenance, and use tensioning bars that fit well and that are kept
in good condition (12025)
Tension the springs from the bottom to the top! Because of the
stretching the spring becomes thinner and longer (number of turns x
wire thickness); if this is not the case, the left and right spring have
been switched!

1)
Mark the spring with a straight line.
2)
Insert the first tensioning bar in the tension head.
3)
Turn the first tensioning bar a quarter of a turn to stretch the spring.
4)
Hold the first tensioning bar and place the second bar in the next hole of the spring fitting.
5)
Turn the second a quarter of a turn.
6)
Hold the second tensioning bar (takes over the tension) and remove the first bar
7)
Repeat steps 3 – 4 – 5 – 6 until the correct tension has been reached.
8)
Secure the spring fitting on the shaft by turning both bolts of the fitting with 27 up to 34 Nm.
9)
Now remove the second tensioning bar
10)
Check the number of turns that the spring has made by counting the number of lines on the spring.
Remove the block of the shaft and the vertical tracks and your sectional door is ready.
Check if the door is well balanced. If not, then check item . (Correction of the spring tension).
27)
Correcting the spring tension
Block the shaft and the door blade
Secure the door so that it cannot go up. Do so for instance by fastening pinchers on the vertical tracks.
IMPORTANT: There is much strain on tensioned springs; proceed carefully at all times, especially when
performing corrective maintenance, and use tensioning bar that fit well and that are kept in good
condition (12025)
You can correct the tension by stretching or releasing the spring with 1 full turn at the most. Make sure that both
springs are equally corrected.
1)
Insert the first tensioning bar in the tension head.
2)
Turn the tensioning bar in the appropriate direction.
3)
Carefully loosen the bolts of the spring fitting and take over the spring tension.
4)
Hold the first tensioning bar and place the second bar in the next hole of the spring fitting.
5)
Turn the second tensioning bar a quarter of a turn in the desired direction.
6)
Hold the second tensioning bar (takes over the tension) and remove the first bar
7)
Repeat steps 4 - 5 - 6 until the correct tension has been reached.
8)
Secure the spring fitting on the shaft by turning both bolts of the spring fitting with 27 up to 34 Nm.
9)
Now remove the second bar.
Remove the blocking of the shaft and the vertical tracks and your sectional door is ready.
