Fit the two telescopic arms to the torsion bars and make sure that they are perfectly perpendicular to them at the same distance from
the door. Adjust the two supports to achieve the above and put some wooden spacers to bring the lateral supports to the required
distance. A spirit level will ensure that the torsion bars are perfectly horizontal. See pic. 8. The lever «B» must be in the released position.

Fit the two telescopic arms and the torsion bars in the correct position and make sure that they are levelled and parallel, door in the
closed position. Partially weld the torsion bars to the lifting arms and operate the door by hand. Verify that it can open fully in a quiet
and smooth way. The lever «B» in the released position. Pic.8.

A good test to verify how well balanced the door is in both directions, ie. lifting and lowering, is to position it 45 degrees from ground
level, as shown in picture 10. Add counterweight to improve running smoothness and balance if required.

The two safety pressure valves are identified by colours: «A»
Open is red; «C» close is green. They are located in the front
of the motor/pump unit, easy to reach for setting operations in
order to meet the power requirements.Pic.11
Once the valves are set, you can fit the cover and the other
accessories. Pic.10
The setting of the safety pressure valves is to be done so to
achieve the exact amout of power required to safely operate
the door. The more you turn the screw clockwise, the more you
increase the power of the operator.
