position when it is released and needs the same strength (approx. a force
of 8 kg) for moving it up or down.
If the Central Carriage is not correctly balanced:
a. Tighten or loosen the Tightener Screw located at the back of the
Column base (refer to illustration below) with an open/box wrench
in order to adjust it. If the Central Carriage is moving up, loose the
screw. If the Central Carriage is moving down, tighten the screw.
b. Check that the Central Carriage remains in position when it is
released. Then check with a Dynamometer that the Central
Carriage needs the same strength (approx. a force of 8 kg) to be
moved up or down.
In case a Dynamometer is not available, place the Central
Carriage to its higher position, release it and check that the
distance from the Rubber Stop to the Carriage is 1 cm maximum
after releasing the Carriage (refer to illustration below), if not
repeat the procedure.
