Mount Aproli 480 on to the bracket and fix it by the 8 screws provided with the equipment
Proceed now to weld the tubular bar to the telescopic arms, with the door in closed position. To ensure that Aproli 480 can exert a
proper hydraulic force on to the door, note the following: the operator is factory preset for mounting a door in closed position;
rotate the operator shaft by approx. 5° degrees clockwise. The door will so get a constant pushing action to stay securely closed.
English
IMPORTANT: once Aproli 480 has been installed and in consideration of the weight of the torsion
bars, it is advised that the existing counterbalance be increased to compensate any extra load and
provide the door with proper balance since the early stage of the installation.
