clockwise; on the contrary, if it doesn’t reach 45°, the spring must
be loaded by turning the central body counterclockwise). Lower
the rod and release it, check that it has reached 45°.
If a load is needed that is greater/lower than that per -

IMPORTANT! For a correct operation of the barrier, when the boom is in vertical position the spring must not
be completely unloaded.
