12. I nsert the 4 screws B88 with the washers BB8 in the slots of the support N29 just fastened to the ceiling and
using a self-locking clamp join an intermediate support N28 previously prepared with the spacers D61 to the
end support using the parts B71 and BB8 fitting them from the rear. Do not fully tighten the screws so that the
supports can still turn slightly between them (fig. 1).
13. Secure the last tread L33 to the support N29 using the screws C53.
14. A ssemble a new intermediate support N28 (as in step 12) and then the second last tread L33. Determine the
depth of the going by fitting a baluster C03 to the parts F48 after fitting the 5 parts F47 without fastening them.
The exact verticality of the baluster C03 will provide the measurement "P" of the going. Check that it is exactly
aligned with the tread above.
15. Finally tighten the end support N29 to the intermediate support N28.
16. C ontinue with the same sequence: a) intermediate support; b) tread to the support above aligning it with the
tread above already fastened; c) final tightening. Prop up the supports as you continue with assembly of the
structure and the treads so that the weight does not bear down on the ceiling. It is essential to fit a prop every
4-5 supports and for safety reasons it is strictly prohibited to climb the staircase before having fastened it to the
ceiling and stiffened it (figs. 5 and 6).
17. A ssemble the corner treads (L35, L36, L37) defining their position with a fulcrum baluster C03 cut to size (fig. 8)
and going through the parts F48.
18. C heck that the entire staircase is vertical and if necessary correct by moving the support N23. Dismantle the
first tread and mark the holes on the floor. Drill the floor using a 14 mm Ø in correspondence to the holes in the
support N27. Insert the dowels C47 and secure in a permanent manner (fig. 1).
19. S ecure the part F48 on the straight tread L33 before the curve going up the staircase at a distance of 85 mm
from the fulcrum baluster C03 assembled previously (see step 17) (fig. 9).
20. S tiffen the staircase in the following points: a) Fit the column S03 in an intermediate position on the floor with
the parts S04, D62 and F49. b) Secure the staircase to the wall using part F12 with part B13 (drill the wall with
a 14 mm Ø bit) and the screws C57 (drill the tread with a 4.5 mm Ø bit) only at the points indicated. Cover with
the part B95 (fig. 11).
To assemble the railing
21. F asten the part F01 to the floor in correspondence to the first baluster (C03) and drill using an 8 mm Ø bit (fig. 1).
Use elements C58, B12, B02 (fig.1). Assemble the reinforcement part F07 on the first baluster keeping one of
the 5 parts F47 above it without fastening it. Warning: the first baluster C03 and the baluster on the straight-line
before the curve (the one near the fulcrum) must be cut based on the height of the other balusters C03 (fig. 9).
22. P osition the handrails A23 after exactly measuring the railing section involved. If necessary, join several parts
using the parts B33 and X01. Starting from the top of each railing section, secure the balusters C03 to the
handrail A23 using the screws C64. Carefully check that the balusters are perfectly vertical during the operation.
Finish the assembly by fitting the caps A21 secured with the parts C64 and X01.
23. S tarting from the baluster C03 at the lower end of the railing section involved, use the dowel BB7 to secure the
part F47 (the one lower down than the 5 already fitted in step 14) at a distance of 4 cm from the tread.
24. M easure the space under the handrail in the centre of the part F47 just secured. Divide the space into 5 equal
parts to obtain the exact distance between centres of the remaining parts F47 and finally fasten them to the
baluster C03 with the dowel BB7, respecting the correct orientation.
25. R epeat the above operations on the baluster C03 at the opposite end of the side of the railing involved,
measuring the distance between centres from the handrail down.
26. S tretch out a wire between the parts F47 already fitted on the 2 poles C03 just prepared so that you have a
guideline to position all the other parts F47 of the same row. Finally fasten the parts F47 using the parts BB7.
27. Prepare all the parts F46, inserting the dowels BB6 and BB7 without fully tightening them (fig 1/1A).
28. P repare the parts A25 with the same length as the handrail for the railing section involved (see step 22). If
necessary, join pieces together using element CA2. The excess part must be cut off after assembly.
29. S tarting from the baluster C03 at the end of each railing section, assemble the first part F46 to the lower part
F47 using the dowel BB6 (fig. 1/1A) without finally tightening.
30. F it all the parts F46 required in the part A25 previously prepared. Finally, fasten it inside the part F46 already
positioned at the baluster C03 letting it protrude by 1 cm (fig. 1/1C). Continue with assembly of all the
remaining parts F46 onto the parts F47 using the dowel BB6. Finally tighten the part A25 to the parts F46 using
the parts BB7. Cut the part A25 taking into account a protrusion of 1 cm (fig. 1/1C).
31. R epeat the above operation for all the remaining 4 rows of parts A25. Fit the parts CA3 at the ends of all the
parts A25 (fig. 1).
32. T o stiffen the railing use the following parts: a) Join the balusters to the parts F08,C49, C50 and a section of
part C03. b) Secure the baluster on the wall with the part F09 using the parts F08. Drill using an 8 mm Ø bit
and use the parts C49, C50, C58, B12 (fig. 9).
33. C omplete the railing assembly by inserting the parts B82 into the lower part of the balusters C03 (fig. 1).
34. F it the finishing parts D59 and D60 of the supports N27, N28 and N29 (fig. 1). Warning: cut the parts D59 and
D60 in height along the pre-engraved cutting line for the support N27.
