force to apply is the same for both directions, all along the operation, and being as low as possible.
2 - By means of a crank, bring the arm in vertical position and ensure that it is locked. Remove screw (12.5) to
disconnect rod (12.3). Manually tilt the arm and check that it remains stable for each position between 0 and 90°.
