1 INTRODUCTION
The Custers stair tower is part of a wide range of aluminium scaffolding products.
If assembled according to the instructions given in this manual, the Custers stair tower
meets the requirements of the EN1004.
The Custers stair tower is available in the following lengths:
- Scaffolding length: 1.8 m and 2.5 m
- Scaffolding width: 1.3 m
This instruction manual gives step-by-step instructions for the easy and safe assembly of the
stair tower. Incorrect assembly can lead to dangerous situations for the user. Read the
instructions carefully before assembling the tower. The tower must be assembled and
disassembled by experienced and skilled personnel.
The user is responsible for making sure the instruction manual is present at the
location where the stair tower is to be assembled and used and that the person who
supervises the work also has a copy.
It there is any uncertainty concerning this instruction manual, please contact your supplier
and/or the manufacturer.

4 SAFETY INSTRUCTIONS
4.1 Checking before assembly
Check whether the people assembling the stair tower are suitably qualified and check if the
location where the stair tower is to be erected is safe and suitable.
Note:
- The surface must be flat and sufficiently strong.
- The area must be free from obstructions, both at ground level and above the ground.
- Check whether the wind conditions are such that the stair tower may be used.
- Check whether all the components are present at the location.
- Damaged, incorrect or non-original components must not be used.
4.2 Assembly
The assembly of the stair tower is described in the assembly instructions. The stair tower
must be assembled by at least two people. Also use safety rails during the assembly. If
necessary, fit the rails temporarily.
The stair tower must be assembled on a flat surface. Check this using a spirit level. It is
possible to correct the stair tower by rotating the wheel spindles’ spindle nut. The wheels
must remain braked at all times, expect when the tower is being moved.
Make sure the wheels are locked, either by tightening the wing nut or by clipping the locking
nock over the edge of the strengthening ring.
The platforms must be secured by sliding the wind securing pin under the rung. The frames
must be locked together using the locking pin. The horizontals or railings must be fitted to
the stands in such a way that the claws’ openings face outwards.
The work platform must have: railings, intermediate railings and toeboards fitted all around.
4.3 Raising components
Components must be raised to higher levels by carrying them up the stairs.
Hoists must not be secured to the stair tower.

6
4.4 Outriggers/elbow outriggers
The outriggers/elbow outriggers stated in the assembly tables must always be fitted as
soon as the bottom section of the stair tower reaches a height of 2 metres.
The basic shape to be used, i.e. the outrigger/elbow outrigger to be used (small or
large), can be found in the assembly tables.
The basic shapes given below must be strictly followed!
If the required shape is deviated from, it may be necessary to use ballast. Contact the
manufacturer or supplier for further information. Small elbow outriggers may be
replaced by small outriggers and large elbow outriggers may be replaced by large
outriggers if, when using the outriggers, the same basic shape is maintained as for
the elbow outriggers. This means that the outriggers must be fitted in the same
position as the elbow outriggers when viewed from above.
Basic shapes
A: Small elbow outrigger, length 1300 mm B: Large elbow outrigger, length 2000 mm
1: Horizontal, length 2500 mm, art. nr. 9501.200.030

7
When the tower is positioned against a wall, do not remove the outriggers/elbow outriggers,
but turn them parallel to the wall.
When the tower is positioned in a corner, remove the inside outrigger/elbow outrigger, and
turn the outside two parallel to the wall.

7 USING THE STAIR TOWER
The following must be carried out each time before the stair tower is used:
- Check whether the base (including the outriggers/elbow outriggers, wheel brakes) of the
stair tower is correct.
- Check whether the entire construction is correct and complete.
- Check whether there are any changes in the circumstances which may affect the safe use
of the stair tower.
The stair tower is intended for providing access to a work location.
It is not permitted to use the stair tower as suspended scaffolding, as an overhanging work
floor or for stepping onto other constructions.
No bridges may be built between the stair tower and a building.
No bridges may be built between two stair towers, unless use is made of objects which have
been specifically designed for this use.
The maximum work load is 200 kg/m2(scaffold class 3). The maximum load may only be
placed on one level of a tower.
It is not permitted to jump on the platform. The hatch in the platform must remain closed at
all times, except for when climbing or descending the stair tower.
The maximum platform height is:
- Indoors: 12 metres
- Outdoors: 8 metres
The stair tower may only be climbed from the inside using the stairs.
No boxes, stepladders or other aids may be placed on the platform to gain extra height.
It is not permitted to work on the stair tower if the wind force is greater than force 6
Beaufort (large branches on trees move, umbrellas blow inside out, wind speed 11 –14 m/s
or approx. 45 km/h).
For an expected wind force greater than force 6 Beaufort, a free-standing stair tower must
be disassembled, moved to an area out of the wind or anchored. This should also be done if
the stair tower is not used.
Pay attention to openings in a building, uncovered buildings and the corners of buildings
which may increase the force of the wind.
Be careful when exerting a horizontal force (e.g. when drilling) which will cause the stair
tower to be pushed away from the construction. The maximum horizontal force is 30 kg.
Horizontals, railings, intermediate railings and diagonals may not be used as steps.
It is not permitted to secure objects which may catch the wind, such as bill boards or
sailcloths, to free-standing stair towers. The stair tower must not be exposed to aggressive
liquids or gasses.

17
8 MOVING THE STAIR TOWER
The stair tower may only be moved manually along the ground. When moving the stair
tower, the normal walking speed must not be exceeded and no people or materials may
left on the tower. Pay attention to obstructions, both on the ground and above ground
level, when moving the stair tower.
The tower may not be moved in winds greater than force 4 Beaufort (dust, earth and
paper blow around, small branches break off, the wind speed is 4 –6 m/s =
approx. 18 km/h).
Be careful when the stair tower is moved over an unsuitable surface (incline,
insufficiently strong surface, holes, etc). Make sure the wheels are braked or released at
the correct times. When moving the stair tower, the support points for the outriggers
may only be a couple of centimetres above the ground. After moving the stair tower, the
support points must be placed back on the ground so that they just support the weight.
9 ANCHORING
The tower must be anchored when the tower becomes unstable, for example, due to a
high wind. The anchoring must be firmly connected to both of the frame’s stands with
couplers. Anchor the tower at reliable and suitable places on the construction or the
building. A minimum of two anchors must be fitted every 4 metres (therefore, one on
every frame).
10 DISASSEMBLY OF THE STAIR TOWER
The stair tower is disassembled in the opposite order to assembly. Start at the top and
remove the toeboards and the toeboardholders.
Components must be lowered to lower levels by carrying them down the stairs.
Disassemble the stair tower from the top to the bottom. Never throw components from
the stair tower.
11 MAINTENANCE OF THE STAIR TOWER
All parts, particularly the pivoting parts and the welds, must be inspected regularly, but at
least once per year, on wear and damages. Lost or damaged parts must be replaced.
Aluminium scaffolding parts are not allowed to be used in the following cases:
when round tubes have one or more dull dents with a depth of more than 3,0 m;
when round tubes have one or more dents directly next to a welding junction, in spite of
the depth or shape of the dent;
when square of rectangular tubes have one or more dull dents with a depth of more than
2,0 mm;
when round or square tubes have one or more sharp dents or cracks, regardless
length, depth or location of these dent(s)/crack.
Pivoting parts, among others castor wheels, must be clean and run smoothly.
Repair of scaffold-material may only be done in consultation with the producer.
