section below. It is possible to extend the section as long as the "device limit development" does not prevent

corresponding rung underlying making sure that the same is blocked. Do the same for the middle section.

Lift the section a bit, for a space corresponding to the space necessary to insert the anti-opening hook.
Turn up to the maximum aperture. On the larger section is fitted, anti/opening device. Open the standing
ladder, rotate the device for join the section opposite of the ladder. Insert the round part of the hook in the
corresponding rung and engage the hook-pillar above the inner band.
Then, stretch the final section for at least four rungs, as described above, and secure it to the middle section.
The ascent must be made on the section opposite the larger section and the final section should be used only as
a guard rail (it is forbidden to climb the final section).
