2.1. Appropriate usage
The folding stair is designed for the usage as an assistant stair. It does not comply with the building law requirements
of necessary or non-necessary stairs, according to DIN 18065. Only original components are to be used for assem
-
bly and maintenance. The folding staircase also falls outside the area of application of the European guideline ETAG
008. According to the country-specific building regulations, the building owner must check whether the use of a
retractable or folding staircase is permissible for his installation situation.
Only use original components to install and maintain the stairs.
The combination with components from other manufacturers and with accessories other than those
mentioned in these assembly instructions may impair safety and is not permitted. The use of the folding
staircase to transport loads is not intended and is not permitted
Load capacity = 140 kg.
The material of the folding stairs is only suitable for indoor usage. When folding in or out, make sure that
you always guide the stairs by the outer stringer to the floor or wall. Letting go beforehand could damage
your stair and floor.
Incorrect grabbing at the step elements could cause the fingers to be squeezed.
Any other use is considered contrary to the regulations and is not permitted.
2.2. Product safety
The folding staircase may only be used in a technically perfect condition and in accordance with the intended use,
being aware of safety and risks, and in compliance with the installation instructions.
Faults that could impair safety (e.g. deviations from the conditions for permissible, intended use) should be removed
immediately.
2.3. Installation
• Check the delivery for completeness of the components. Check all components for damages and sort them out.
•
Before starting the installation, compare your storey height with the required step-rise combination in the storey height
table in section 9 or in the Häfele catalogue. In case of dimensional deviations, please do not start the installation, but
contact your clerk.
•
Only use dowels or fasteners that fit your masonry and are designed for sufficient load capacity. It is necessary to pay
attention to the manufacturer‘s instructions for use (dowels, screws, etc.).
• If installation aids (e.g. ladders) are used, the respective operating and user instructions must be followed. .
•
At least two persons are required to mount the folding staircase on the wall (three persons are recommended).
3. Maintenance tips
In general, impurities on all surface coatings should only be cleaned with suitable substances that are gentle
on the material. Do not use any acids or alkalis that could attack the surfaces. Individual care instructions for
the different surface coatings are given in the following table:
Natural,
untreated
The natural wood version is very sensitive to dirt, so treatment with oil, varnish or simi
-
lar is recommended. Precisely fitting anti-slip foils that protect the surface can also be
purchased as accessories. Impurities can only be removed with fine-grained sandpaper
(e.g. grit 180).
The layer thickness of the veneer is 0.8mm - this can be removed if you overgrind
4. Disposal
Disassembly takes place in reverse order to the assembly. The product must be disposed of properly in accordance
with its materials and regional regulations.
