GENERAL REMARKS CONCERNING THE METHOD OF ASSEMBLING STAIRS
The following instructions provide help in proper selection of all stairs parameters and tools and is a guidebook
describing step-by-step a self-assembly of modular stairs ASTA of TLC company (pages 2 - 12). You will find here
also guidelines concerning safety of assembly and operating conditions as well as technical parameters (pages 14
and 15).
BEFORE THE ASSEMBLY
Go through the entire instructions and become acquainted with every stage of the assembly and manufacturer’s
recommendations. It will allow you to prepare all necessary tools before you start the assembly. Make sure that
you have obtained all elements. The easiest way is to compare the obtained packages with tables containing the
list of elements depending on the number of stairs. Everything was packed and described in order to facilitate you
finding right element.
Before you start the assembly, make sure that you are well rested and in good health. People under the influence of
alcohol are not allowed to perform the assembly. During the assembly you should strictly observe manufacturer’s
recommendations as well as health and safety regulations (page 14).
INTENDED USE AND EXPLOITATION OF MODULAR STAIRS
Modular stairs ASTA are intended both for living (living room, staircases) ant utility spaces (garages, cellars,
workshops). ASTA stairs may be used also as external stairs in gardens, access to the higher floor or terrace
being at higher level. Stairs are not adapted for use in rooms where the presence of big groups of children without
supervision is expected and in buildings intended for people with disabilities.
Modular stairs ASTA should be used in accordance with their intended use as the element of a building or the shape
of the land, which allows communication between different levels.
GENERAL MANUFACTURER’S RECOMMENDATIONS
Modular stairs ASTA should be installed in accordance with assembly instructions and only with the use of original
parts provided individually for every module. Only this kind of assembly allows long and safe utilisation and gives
the manufacturer’s warranty.
Manufacturer of modular stairs ASTA is not responsible for:
• use of elements of ASTA stairs in other structures
• stairs assembled with the use of other elements than those provided and recommended by the Manufacturer
• stairs assembles not in accordance with the Manufacturer’s Instructions.
ATTENTION!
• In the case of the assembly of stairs with parallel run towards the wall, there should be provided an appropriate
space between the railing and this wall. Due to safety reasons, it is recommended that the space between the
railing and the wall was 50 mm wide.
• Stairs must be installed with railings (on both sides). Except the cases where the stairs are installed against the
wall. It is allowed then to install only one railing, but in order to ensure the appropriate rigidity and strength of
the structure, the stairs should anchored to the wall. You can find more information on page 11.
• Railings of the stairs are mounted on the stairs of more than three steps.
• Number of steps in one run of stairs should not be higher than 14.

ASSEMBLING BEAMS BEDDING ANCHORS IN A WALL AND FIXING LEFT BEAM
Main elements of the stairs consist of two side beams composed of modules 3, 5, 7 (left beam) and 4, 6, 8 (right beam).
You should assembly the beams together on flat surface, in order to ensure right placing of the elements. At this stage
you should use fasteners D, J, M and G, and while assembling comply with dimension S from the previously determined
height of the stairs.
Drawing presents the manner of installation of the left beam. Installation of the right beam should be done in an
analogous manner.

ATTENTION
Walls and floor may be made of various types of materials, which requires using appropriate fixing materials
- mechanic and chemical. You can obtain assistance concerning the selection of anchors in a technical specialty
store.
Stairs manufacturer ASTA recommends using anchors M12 of anchorage depth of 130mm. Anchors should
be bedded in accordance with manufacturer’s instructions. In the case where stairs are assembled to steel
elements, you should use screws M12 in class 8.8 and spring washer.
Stairs should be anchored to a stable ground allowing the use of the anchor 130mm long. In the place of
anchoring in a wall, you should ensure a firm support for the end module. It is not permitted to screw an end
module directly to the elevation made of insulation materials such as Styrofoam, wool etc.
If you decide to install stairs to the wall covered with elevation, cut out a fragment of insulation and use an
intermediary installation element (channel, closed profile) of dimensions corresponding to insulation layers. In
case of any doubts ask an expert.

FIXING RIGHT BEAM AND INSTALLING STEPS
Right beam should be screwed to the wall with screws left slightly loose, in order to allow adjustment (detail B).
After the installation of left and right beam, install steps, remembering to screw them with one screw (detail C). At
this stage you should use fasteners B, H, K and E. Start with the installation of three steps: at the beginning, in the
middle and at the end of stairs (as in the drawing below), which will allow you to make the structure more rigid and
will facilitate the installation of remaining steps. Because the stairs will be later anchored at the base, first step
should be installed only after screwing the stairs to the ground.
After installation of the stairs (apart from the first step), tighten screws fixing the right beam to the wall, while
verifying and making adjustments in the position of stairs. Make sure that the steps are placed horizontally, and feet
of both beams stand firmly on the ground. You can verify the levelling of the steps with a level.
FIXING STAIRS TO THE GROUND AND INSTALLATION OF THE BEAMS
Sliding a drill through oblong holes in stairs feet, drill holes for anchors in the ground. Before you decide where drill the holes,
make sure that the beams of the stairs are placed perpendicularly towards the wall. Then bed the anchors in accordance
with the manufacturer’s instructions and screw the feet. If there is 10 or more steps, you must install additionally grips for
cables 14 and 15 (detail D). You will find the following manner of cables installation on the next page.
Screw railings (9 and 10) to every step, except from the first one. Upper railing screw is also second screw fixing a step. For
the installation of the railing use fasteners A, H, K and E and saddle washers 13 (detail E). While installing the railing on the
subsequent steps, screw them together using fasteners 12 (detail F). Try not to move tightened fasteners, because it may
result in the damage to the paint coating.
ATTENTION
Under no circumstances enter the stairs before the completion of the installation. Only after screwing all
elements and proper anchoring of the stairs, the structure guarantees the safety of use. Entering the stairs
during the installation may result in the occurrence of serious accident, and may permanently damage the
structure.

ATTENTION
It is allowed to install the stairs next to the wall with one railing.
In such case you should additionally anchor the stairs using holes
destined to the installation of the railing. The stairs should be
anchored: in third module from the bottom and in third module
from the top, and, depending on the number of steps, in every third
module. For anchoring we recommend anchors M8 100mm long.
While installation and assembling the railings, make sure that they
are placed in one line. Railings are carrying element of the ASTA
stairs and their proper installation has a considerable impact on
the rigidity of the structure.

INSTALLATION OF FIRST STEP AND STIFFENING BRACINGS
In the case where there is 10 or more steps, it is necessary to install bracings in the form of cables 14 and 15. At the
previous stage, you screwed lower grips for the cables to the feet of the stairs. Cross the cables below the stairs
and fix upper grips to the seventh modules under screw D and washer J (detail G). Stretch the cables evenly with
Roman screws. The installation of bracings is necessary and improves the rigidity and stability of the stairs.
The last stage is the installation of the first step. For the installation use fasteners B, H, K and E (detail H).
ATTENTION
After finishing the correct installation of stairs you should perform an inspection of the structure. You should
check:
• tightening of all screw connections
• correctness of the installation of anchors to the existing structure
• correctness of the installation of fasteners 12 to the posts (railings)

It’s high time to admire your new stairs and yourself as well. In the end, the self-assembly of ASTA stairs allowed you
to save some money. With proper servicing and regular inspections, your new stairs will be there for you for many
years.
Before you start using the stairs vacuum them with a soft vacuum attachment and wipe with a damp cloth remaining
dust. Wooden elements of the stairs should be preserved only with substances intended for this purpose. Before
using a preserving substance, make a test on a small, hidden surface. Do not use any diluents, removers, rinse aid and
strong detergents etc. It is forbidden to leave on stairs excessive amount of water or other substances, because it may
permanently damage the structure.

ATTENTION
If you decided to have natural wood steps, remember to provide appropriate using conditions. Wood is
natural material with hygroscopic structure. That is why the Manufacturer cannot guarantee that the original
structure will be preserved if the stairs are used in external conditions - wood may become deformed, some
cracks and micro-cracks may appear etc.
