them turning with the nuts. Make use of the relevant seat for the wrench on the cable
socket.
8. Activate the movement of the extendible arms several
times and check that the residual loads on the ropes are
10Nm.
9. This procedure could require several attempts before it is
completed correctly.
10. The adjustment is correct when the ropes do not emit
any noise during extension or return and the torque value
prescribed is reached on all of the ropes.
11. Once calibration has been concluded, tighten the counter‑
nuts and re‑mount the sump.
