1Overview
1.1 Application
A Folding tower is intended for various, mainly light work at height, where a solid, stable and safe
work floor is required. The tower should not be used as a stair tower, to provide access to other
constructions. If in doubt, always consult your supplier or manufacturer; the contact information is at
the front of this brochure.

2Assembly and use
2.5 Positioning of the Mobile Folding tower
Sureface
Always place the Folding tower a stable and horizontal surface. Make sure that the tower cannot sink
into the ground. In addition, the general slope of the surface may not be steeper than 1 degree. So,
at a height of 4 meters, the deviation may amount to a maximum of 4 cm.
Obstacles
Position the Folding tower in such a way that no danger to the user can arise when descending. Pay
attention to obstacles on the ground and/or obstacles at height. The user should reach the upper
platform without extra effort.
Maximum height
This depends on the placement and type of Folding tower (see Table 1).
Weather conditions
Consult the weather report to determine safety in various weather conditions. Consider the following
conditions and use common sense.
Wind force
Precipitation
Remove snow and ice from the Folding tower before starting work. If necessary, sprinkle sand on the
work floor to prevent slippage.
Cold
Avoid using mobile scaffold towers at temperatures below freezing.
2.6 Personal protection equipment
•Always wear work gloves, safety shoes and a safety helmet.
•When working at height, use a life-line.
2.7 Assembly
For checking for damage: see section 3.
There are no tools required for assembling a Folding tower. Folding towers are also not designed to
be hoisted.
At wind force 6 or higher a scaffold may not be used.
Also, any materials such as canvas that are installed must be removed.
Check all components (use the list of components) that are required for assembly, are
present and undamaged. Damaged components should not be used.

2.8 Assembly Instructions
Check that all materials meet the annual inspection labels and check all materials for damage. If in
doubt, contact ASC or your dealer for any questions. Aluminum Scaffoldings should only be erected
by people with enough and proven experience.
Floor height 0.70 m (A)
1. Insert the wheels (8) into the folding unit 6-rung (1) at the bottom
and secure with a locking clip (9).

the 2nd rung and secure the folding unit with a locking clip in the
hinge piece.
3. Put the wheels (8) on the brake and place a horizontal brace (4) on
the upper rung (opposite the folding unit). This will create a handrail
at hip height.

2.9 Use
Extension/increase
Never elevate the Folding tower with a tool. Therefore, do not use stairs, ladders, crates or steps on
the Folding tower unless the stairs or ladder are intended to be part of the Folding tower.
Maximum permissible weight
Please read on the sticker on the platform what the maximum load is. Each ASC Group scaffold may
be loaded to a maximum of 200 kg/m2 and never more than 375 kg in total. This means on average:
two people with (hand) tools. The maximum horizontal load is 30 kg.
Before use, please check that:
•All parts are still present
•All the parts are still properly attached
•The tower is still perpendicular
•The scaffold is clean
•There are any changes in the surroundings which may affect safe use
•The brakes are working on the wheel
•The stabilizers are touching the ground
•All locking clips are correctly in place
Never use a mobile scaffold tower near non-insulated, electrical installations or machinery.

Further loads weights
When working on a scaffold, force is applied to the scaffold. Consider the push-off against the
building when drilling into a wall or the wind tunnel effect (additional wind load) between or in
front of large buildings. Such external loads must always be taken into consideration.
Stabilization
Stabilizers must always be installed for a Folding tower
structure from a floor height of 2,20m. Stabilizers are
supplied in an adjustable version.
They are placed on a Folding tower which is placed against a
building as shown in figure A and a freestanding scaffold as
shown in figure B.
Sideboard set
Sideboards are always required on the platform being worked on.
Security
Do not leave a mobile Folding tower unattended in a public place for an extended period. If this is
nevertheless necessary, the Folding tower can be secured to a fixed object with a ring lock. To do
this, put the ring lock through one of the frame's compartments and attach an anti-climb device.
Relocation
A mobile Folding tower can be moved by dismantling and rebuilding it. After moving the Folding
tower, it must be put back into plumb; therefore, go through the checklist again from Section 2.9.
2.10 Chemical products
3Inspection, care and maintenance
According to the regulations one must work safely at heights. On an ASC Mobile Tower, it is not
obligatory to wear extra fall protection (provided that the recommendations in this manual have
been followed).
3.1 The Health and Safety Law
The Working Conditions Decree is a concrete elaboration of the Safe Working at Height Act. It states
that everything above 0 meters is 'working at height' and is therefore a situation with increased risk
of injury. This also means that all materials must be properly manufactured and checked in a quality
cycle. ASC tests all materials and performs strength calculations. The user must also have the
material inspected annually for defects.
Do not attach a winch or hoist to the scaffold, but use a
rope to lift parts, materials and tools (possibly in a bucket).
Avoid contact with acids and chemical products. These can cause corrosion to the
aluminium, which can affect the strength of the aluminium.

10
Annual control
Your ASC Mobile Tower must be inspected for any defects annually by an expert.
The ASC Group can perform this control for you.
Self-inspection
The ASC Mobile Tower can be inspected by yourself. Before each use, always check the components
for any damage. We certainly recommend larger companies to do a monthly inspection of all
components of the Mobile Towers and to record this inspection. If you are in doubt about damage,
consult an accredited inspector.
Damages
Examples of the most common damages on aluminium Folding tower;
•Components: if a claw or a sport is loose, the mobile Folding tower must be rejected.
•Dents and or holes: if there is a big dent in the aluminium or even a crack or hole, the Folding
tower must be rejected.
•Contamination: if there is too much concrete, paint or other non-removable contamination
on the components, the Folding tower must be rejected; after all, you can no longer judge
whether the components are still intact.
What to do in the event of damage
If there is any damage, which cannot be repaired, the component must be taken out and replaced. If
repairing is possible, please contact ASC Group for further information.
Repair
3.2 Transport
•Always transport the components in accordance with the locally applicable legislation.
•Stack the components correctly for transport; never place the heavy components on top.
•Transport the components of a Folding tower, preferably standing, f.e in a carrier.
•Handle the material with care. Do not drop components onto a hard surface; this can reduce
the quality of the material.
3.3 Maintenance
•Make sure the Folding tower material is clean, especially the connecting pins. The frames
should go in and out easily.
•Make sure the pawl of the hook of the diagonal and horizontal braces is clean. If necessary,
lubricate it with a little oil. The same applies to the wheel spindle.
•Replace missing and broken parts in time.
3.4 Storage
Store components of the Folding tower preferably in a dry, clean, dark and frost-free place.
Repairing a component must be carried out by a certified body or person.
