The aluminium scaffolding is intended to enable users to reach
high-level working areas in buildings and in the open.
The employer responsible for the work to erect the scaffolding
is responsible for providing the instructions for erection and
use to the specialist staff who erect, use or supervise working
with the aluminium scaffolding.
As a minimum, 2 persons are required to erect and dismantle
the aluminium scaffolding.The persons carrying out the erection
work must have sufficient knowledge and experience for this
task.
The erection work must be managed by supervisors with
appropriate expertise in this area, who are also able to
guarantee the work is carried out in accordance with the
regulations.
All instructions and safety advice similarly apply for private
users. The private user is to take care, in accordance with
the instructions, that the respective regulations are similarly
observed.
Permitted works on the aluminium scaffolding are, for
example, inspections, servicing works, cleaning works, i.e.
works or measures to preserve the condition of buildings
where storage of building materials or building components is
not required.
The aluminium scaffolding can therefore be erected in a
central position or against a wall, in accordance with the
instructions for erection and use.
General instructions
• Thealuminiumscaffoldingshouldonlybeerectedand
dismantled by persons familiar with the instructions for
erection and use.
• Damagedcomponentsmustnotbeused.
• Onlytheoriginalcomponentsaretobeused,inaccordance
with the manufacturer’s instructions. Before being erected,
all parts are to be checked to ensure that they are in a
fault-free condition. A check is similarly to be made to en-
sure that all construction components and safety equipment
are complete and available for use.
• Thesurfaceonwhichthealuminiumscaffoldingisbeing
erected must be capable of bearing the permitted total
weight of the scaffold.
• Thesitemustbelevelandfreeofobstacles.Windcondi-
tions must also be taken into account for this.
It must be possible to align the aluminium scaffolding to
within an incline of 1% from the vertical.
• Beforeerectingthescaffolding,acheckmustbemade
to ensure that all the components for the scaffold are
complete, and a test of function for the safety devices must
be carried out.
• Thescaffoldingistobeerectedinaccordancewiththe
instructions for erection and use.
• Assemblyanddisassemblyofthe1stplatform9902-101
and 2nd platform 9904-101 of the scaffold requires at
least 2 persons.
• Thesepersonsmustbeequippedwithsuitableworkclothing
and safety shoes. Where applicable, excessive leaning out
beyond the edge of the platform is to be avoided when
erecting and when using the aluminium scaffolding.
• Theintermediaterails,ballaststruts,guardrailsandbraces
of the working platform must always be positioned on
the rungs of the ladder as shown in the instructions for
assembly and use.

• A2-partsideguard(consistingofguardrailandknee-
height rail) must be attached to intermediate platforms. A
3-part side guard (consisting of guard rail, knee-height rail
and toe board surround) must be attached to the working
platform.
• Whenmountingtheladdersectionsforthe1stand2nd
platform, make sure that the connectors are inserted fully
into the rails and that they are properly secured using bolts
and split pins.
• Theverticalpositioningofthescaffoldistobechecked
in both the lengthwise and the crosswise direction using
a spirit level while the scaffold is being erected. If the
scaffolding needs to be raised on one side in order to be
positioned vertically, then the running wheels (lower side
frame) must be supported to prevent them slipping away.
The stabilizer bars must similarly be secured to ensure they
do not drop away. Note: this applies especially to grassed
areas of ground!
• Takeaccountofexcessivehorizontalforcesthatcouldcause
the scaffold to tip over, e.g. additional wind loads such
as tunnel effects in open-ended buildings, on unfinished
buildings and at corners.
• Beforeuse,acheckshouldbemadetoseethatthe
aluminium scaffolding has been properly and fully erected
in accordance with the specifications of these instructions
for erection and use, and is standing vertically.
• Beforeuse,itshouldbeensuredthatallnecessarysafety
provisions to prevent tipping have been carried out.
This is ensured by attaching stabilizer bars and ballast
weights, and by depressing the brake lever on the running
wheels.
Note: if specified, stabilizer bars and ballast weights are to
be applied.The individual types are described in the instruc-
tions for erection and use.
• Whenmovingthealuminiumscaffolding,nomaterialsand
no person or persons should be on it.
• Thealuminiumscaffoldingmustonlybemovedbyhand,
and only on a firm, even, obstacle-free surface. Before
moving the scaffolding, the brakes on all 4 running wheels
must be released.
When moving the scaffolding, care must be taken to ensure
that normal walking pace is not exceeded, and that the
scaffold must only be moved in the direction of its longer
side or pivoted around one of its corners.
• Whenerectedagainstawall,thescaffoldingmustonly
be moved parallel to the wall in a lengthwise direction. In
doing so, care must be taken over obstacles at height.
• Tomovethealuminiumscaffoldinginitsassembledstate,
the stabilizer bars should only be lifted so far that the feet
of the stabilizer bars are a maximum of 3 cm above the
ground.
The scaffolding should not be crashed into any obstacle.
• Itisnotpermittedtomovethescaffoldingonaninclined
surface. When moving the scaffolding, wind conditions
must be taken into account.
• Oncethemoveiscompleted,therunningwheelsaretobe
locked in position by depressing the brake levers and the
stabilizer bars are to be firmly attached again to provide
support.
• Attachingandusingliftingequipmentanddevicesisnot
permitted.
Movement of tools and materials is only permitted via the
access openings provided on the scaffolding, i.e. through
the opened access hatch.
When not in use, the access hatch is to be kept closed.
• Leaningoutoverthesideprotectionorbracingoneself
against the side protection is not permitted.

• Noattemptshouldbemadetoattachseveralaluminium
scaffolds together to create a single scaffold to cover an
area or space, or to act as a load-bearing element.
• Accessingandcomingdownfromtheworkingplatformis
not permitted via any access route other than the access
hatch provided. Accordingly, one should only go up using
the inside of the ladder sections on the aluminium scaffold-
ing.
The hatch to the working platform should only be opened
in order to climb through, and should be kept closed at all
other times.
Onthealuminiumscaffoldingwith2workingplatforms
(model 9900-101 + 1st platform 9902-101 + 2nd
platform 9904-101), the access hatches are to be arranged
at alternate ends on alternate levels.
• Attachingbridgingelementsbetweenthealuminiumscaf-
folding and a building is not permitted.

• Onthealuminiumscaffoldingwith2workingplatforms
(when using the 2nd lift 9904-001), it is only permitted to
work on one of the working platforms.
• Ifthealuminiumscaffoldingisbeingusedontheoutsideof
buildings, then as far as possible it is to be safety secured
onto the building or onto another solidly-constructed ele-
ment.
• Ifbeingusedintheopenoronopenbuildings,workisto
be stopped if the wind increases and/or at the end of the
