5. Inspection upon delivery
Upon receipt, check that the tower scaffolding is complete and undamaged.
Contact your supplier immediately if you notice that the components of the tower
scaffolding are damaged or if the components that have been delivered are
incomplete.
6. Safety instructions
6.1. Check before assembly
Verify whether the personnel assembling the scaffolds are sufficiently qualified and that
the place where the tower scaffolding is to be erected is safe and suitable.
Caution:
 The ground must be sufficiently load-bearing and flat;
 The space must be free of obstacles, both on the ground and above ground;
 Verify whether the wind conditions allow safe use of the scaffolding;
 Check to make sure that you have all the components at the workplace;
 Never use damaged, incorrect or non-original components;
 Be aware of possible electrical hazards.
6.2. Personal protective equipment
 Always wear work gloves, safety shoes and a safety helmet.
6.3. Assembly
The assembly of the mobile scaffold tower must be carried out by at least 2 persons.
Please note the following:
a) User training courses cannot be a substitute for instruction manuals but only
complement them;
b) Only the original Custers components specified in this manual shall be used;
c) Damaged or incorrect components shall not be used;
d) This product shall only be used according to the instruction manual
e) Mobile access and working towers designed in accordance with EN1004-1 are
not anchor points for personal fall arrest equipment;
f) Working is only permitted on a platform with a complete side protection
including guardrails and toe boards.
Use leading guardrail frames during the assembly to prevent persons from falling:
when you stand on a platform you must be protected by guardrails on hip and knee
level on all four sides.

7
The mobile scaffold tower must be erected flat with a maximum inclination of 1% (a
maximum of 1 cm inclination over a length of 1 metre); check this with a spirit level;
correction is possible by tightening the spindle nuts of the casters. The casters must
always be in locked position, except for relocating the scaffold. Make sure that the
casters are locked, either by tightening the wing nut, or by tilting the locking tab over
the cantilevered edge of the chord stiffener.
The platforms must be secured by sliding the pawl of the blow-away protection under
the rung. The frames must be secured using locking pins in the lowest holes in the
uprights in order to fix the spigot pen of the frame underneath.

Horizontal braces/guardrails must preferably be positioned on the uprights in such a
way that the openings of the claws point outwards.
Frame security pin

9
There must always be at least 1 platform with hatch on the working level; the working
level must be fitted with: guardrail, knee railing and toe boards all around. There must
always be at least one platform with a hatch on the resting level. The resting level
must be fitted all around with guardrails and knee railings and must be installed every
2 metres.
A resting level is converted into a working level through the installation of toe boards
all around.
Be aware that one level only shall be a working platform at one time.
It is to be taken into account that the correct platform height in relation to the
required work should be selected.
On a working platform a maximum of two persons are permitted.
The horizontal and diagonal braces have a self-locking claw. To unlock, just push the
coloured plastic part inwards and the brace can be removed.

6.4. Lifting up components
Lifting up components onto higher areas should be done by passing the components
from platform to platform. Parts can also be lifted upwards with a sturdy rope. Use a
proper knot, loop or hook to secure the components. Hoisting equipment may not be
attached to the scaffold.
6.5. Outriggers and stabilizers
The outriggers (arch shaped stabilizer that allows a castor to be attached) / stabilizers
specified in the table must always be fitted once the lower edge of the scaffold has
been erected. During assembly, the upper sides of the outriggers / stabilizers must be
connected to the underside of the rungs in order to prevent them from sliding upwards
unintentionally.
The basic form to be used, i.e. the outrigger to be used (small or large), can be read
in the composition tables.
The basic forms shown below must be strictly adhered to!
If the designated form is different, ballast weights may be required; please contact the
manufacturer/supplier for this. Small outriggers may be replaced by small stabilizers
and large outriggers by large stabilizers, provided that the use of stabilizer follows the
same basic form as the outriggers. This means that the stabilizers, when viewed from
the top, must be mounted in the same position as the outriggers.

If the mobile scaffold tower is placed against a wall, do not remove the outrigger /
stabilizer, but turn it parallel to the wall. If the mobile scaffold tower is placed at an
angle, remove the inner outrigger / stabilizer, and turn the outer two parallel to the
wall.

6.6. Mobile guards
In order to prevent falls during assembly and dismantling of the mobile scaffold tower,
leading guardrails or guardrail frames must be used. The basic principle here is that
the edge protection, consisting of at least one guardrail on hip and knee level, is fitted
before entering and standing on the platform.
Custers Mobile Guard leading guardrail frames:
 are moving along with you during assembly and disassembly of the scaffolding from
the one to the other level;
 offer protection until the moment the definite guardrails are positioned;
 provide protection against falling, before entering the platform through the hatch;
 are fitted and removed from a secure place;
 are easy to handle and easy to apply;
 on the working platform they can be used as permanent guardrails if combined with
correctly positioned knee rails.
During the assembly phase of the mobile scaffold tower, the Mobile Guard guardrail
frames must be used as follows (complete assembly sequence, see relevant sections):
Intermediate
platform

14
Mount both Mobile Guards (with the claws over the upper rungs) standing on the
intermediate platform; make sure that the claws fall properly over the rungs
Mount the platform without hatch & the platform with hatch from the intermediate
platform
Climb up, open the hatch and sit down in this opening so that you can mount the knee
rails on the second rung above floor level. Get on the floor and make some space
between Mobile Guard + knee rail and the uprights of the frame, than mount 4
horizontal braces on the uprights above the second and fourth rung. The temporary
Mobile Guard can be used again for the next section of the scaffold until the needed
platform height has been reached.

On the upper level the Mobile Guard is used as a permanent guardrail by adding a
knee rail in the hooked in on the vertical arms of the Mobile Guard and mounted on
the second rungs.
During disassembly of the scaffolding above mentioned has to be done in reversed
order.
ATTENTION:
When you disassemble the knee rail can be taken out whilst sitting in the open hatch
as follows:
1 (if needed) remount Mobile Guards with knee rails on the second rung
2 unlock the braces at the longest distance from the hatch and lift them slightly by
rotating the closest vertical tube with hook in the direction of the hatch side of the
platform, the hook lifts and supports the horizontal guardrail
3 sit down in the opened hatch and unlock and take out the knee rails

10: Place one platform with hatch (on the
5th rung from the top, slide both blow-
away protections under the rung;
11: Lock the brakes and set the
scaffold level by twisting the
spindle nut of the casters;
Now place the four (large or small)
stabilizers:
12: Place the upper coupler under the 6th or
7th rung at the small leg, 9th or 10th rung
at the large leg;
13: Put the foot on the ground with
observance of the designated basic form
(see 4.4);
14: Make sure that the lower coupler falls
between two rungs;
15: Rotate the stabilizer in such a way that
the designated basic form (see
4.4) is maintained;
16: Tighten the lower coupler
by hand on the upright and slide the
coupler upwards over the upright so
that the leg is slightly tensioned and
slightly tighten both couplers;
17 Climb to the 2 m. level through the
hatch; sit down in the hatch and mount
two knee rails on the 2nd rung and in the
hooks of the Mobile Guardrails and
move them slightly inwards.
18 Now you are allowed to stand on the
platform where you put horizontal
braces on the uprights just above the
2nd and 4th rung.
