Spring force
Do not carry out this operation until the arm is
positioned correctly. Failure to do so may damage the
operator.
Regulate closing force with the door in closed
position and without power.
The spring must be pre-charged in closing
position. Otherwise the spring will be at rest, and
spring adjustment will have no effect on closing.
Adjust spring force as necessary.
To do this, turn the screw (1) clockwise to increase closing
force, or anti-clockwise to reduce closing force.
The door must be easy to open by hand, and the operator
must close it fully (gently and without slamming the door).
