4.2 General safety
The machine is constructed in accordance with the European machine directive (98/37/EC) and
applicable norms and is safe to operate. However, due to its work processes the machine has parts and
points that cannot be protected without impairing the function and operating capacity of the unit. For
this reason, good personal safety practice is required to protect personnel and equipment. Risks can
arise from this equipment if it is used incorrectly by untrained personnel or for non-intended purposes.
•Before transporting, assembling, commissioning, dismantling and maintenance, read and observe
exactly the machine assembly and operating manuals and safety notes!
Read and understand assembly and operating manual first;
during work is too late!
•Keep the operating manual accessible in close proximity to the machine.
•The generally valid, legal and other binding provisions for accident prevention and environmental
protection in the respective country in which the machine is being operated are considered a
supplement to the assembly and operating manual (e.g. wearing personal protective gear such as
hard hat, safety shoes, rope harness, etc.).
•Observe attached notices and warning signs.
•Only work while wearing close fitting clothing, safety shoes
and hard hat. Do not wear jewellery such as necklaces and
rings. There is a risk of injury from getting caught or being
pulled in.
•Find a doctor immediately if there are any injuries or
accidents.

Working Platform
Assembly and Operating Manual Page 10 of 52 BL 061 U Edition 06.2007
Consequences of not complying with safety instructions
Non-compliance with safety instructions can result in danger both for persons as well as for the
environment and the machine. Non-compliance can lead to a loss of any compensation claims.
4.3 Operating safety
•The machine must be set up and dismantled according to this assembly manual and under
supervision by expert personnel determined by the employer.
•Observe bearing capacity on supporting surfaces (roof extension, etc.).
•Only use the machine in technically fault-free condition and in a safety and risk conscious manner,
while observing the operating manual.
•Immediately remedy faults that could impair safety.
•Immediately shutdown the machine if there are safety-relevant changes to the unit or its operating
behaviour, and report the fault to the company management or its representative.
•Do not carry out any changes, mount parts on or make conversions to the machine. This also
applies to installing and adjusting safety features, such as e.g. limit switches.
•Do not change, remove, override or bypass safety devices.
•Immediately renew damaged and/or removed notices and warning signs as well as safety labels.
•Unplug machine when work is interrupted.
•In situations that present a risk for the operating personnel or the
machine, the machine can be shutdown by pressing the EMERGENCY
STOP button (1) on the central control of the machine.

Assembly and Operating Manual Page 11 of 52 BL 061 U Edition 06.2007
4.3.2 Safety notes for assembly, operation and transport
•Before starting work at the place of utilization, acquaint yourself with the working environment,
e.g. obstacles in the work and traffic area and necessary safeguarding of the construction site from
public transport.
•Only load and transport equipment that has been carefully dismantled, packed and tied securely.
•Always secure the machine against unauthorized use (de-energize)!
•Position the material carefully on the platform; material that tends to slip or is higher than the
platform or could fall must be secured (think about sudden winds).
•Do not stand or work beneath working platform!
•Do not place objects under the working platform.
•Distribute loads evenly on the platform, observe max. bearing capacity.
•Check at least once a day for externally recognizable damages and defects. Immediately report any
changes or malfunctions determined to the company management or his/her authorized
representative. If necessary, shutdown and secure machine immediately.
4.3.3 Safety instructions for maintenance
•Remove mains plug before any maintenance work.
•Only allow servicing and repair work to be carried out by authorized and qualified personnel. In
this case, pay attention e.g. also to the special risks present during work on electrical systems.
•Professionally re-attach all dismantled safety devices after maintenance work.
•Independent conversions or changes to the machine impair safety and are not permitted.
•Spare parts must correspond to the technical requirements of the manufacturer. Recommendation:
Only use original spare parts from GEDA.
4.4 Promoting use of operating manuals
Operating manuals are rules that the employer puts together for safe operational procedures. This
refers to binding instructions that the employer issues within the context of his management rights. The
employees are obliged by the accident prevention guidelines to follow these instructions.
The general obligation of the employer to create operating manuals and make them public must be
derived from the accident prevention guideline “General Instructions”.
According to this guideline, the employer has to fulfil the instructions for preventing work-related
accidents and must instruct the insured parties in risks occurring during their work and the measures
for averting said risks. These requirements can be fulfilled with the aid of operating manuals.
This operating manual is to supplement national guidelines on accident prevention and environmental
protection!
EN 60204-1 and EC directive 89/655/EEC regarding basic instructions for safety and health protection
when using work equipment by employees during work.

NOTE
This assembly and operating manual describes the AB 450/ 650 with a 400V drive unit. For the AB
450/ 650, the following items are different:
•The assembly height is limited to 55m (otherwise the voltage drop in the power line would be to o
heavy).
•The cross-section of the power line fort he control has to be at least 4mm².
•You have to use a special single control or central control for 230V/ 50Hz.
7Requirements at place of installation
Electrical connection (on site)
•A building site main switch cabinet with residual 400V 50Hz current circuit breaker and fusing
fort he feedpoint with 3 x 16 A slow-to-blow is required on the construction site. For the AB
450 with 230Vdrive unit you need a building site main switch cabinet with a 230V 50Hz
feedpoint with a minimum fusing of1 x 16 A slow-to-blow.
- Connect the feeder for the control to the building site main switch cabinet (for the 400V –unit a er
CEE plug 5x16 A, 6h, red with phase inverter).
•You need a rubber insulated flexible cable of at least 5 x 2,5 mm
2
or 3 x 4 mm
2
respectively (fort
he 230V drive unit (see accessories), in order to avoid voltage drop and thereby any loss
concerning the motor power.
NOTE
If the power supply is poor you could change to a different power consumer.

8Transport
•On receipt of delivery of the working platform, check for any transport damage and for
completeness according to your order.
•Immediately notify the carrier and dealer if there is any transport damage!
•The working platform can be disassembled into individual parts for transport to the construction
site.
9Construction
The working platform must be constructed in accordance with the assembly and
operating manual and under supervision by specialist personnel determined by the
employer!
These qualified personnel must be acquainted with the assembly and operating
manual, have sufficient experience and be informed about the risks involved in
handling the working platform.
9.1 Assembling the roof extension
9.1.1 Safety notes
The roof extensions are safety components and may only be used if they are not damaged in any way.
Damaged parts may be replaced by original spare parts from the manufacturer. The roof extensions are
used to secure the bearing rope and safety rope and are intended for use on flat roofs. One roof
extension is required per winch on the working platform. Apart from the ropes on the working
platform, no other loads may be suspended on the roof extensions.
Before setting up the roof extension, determine the number of ballast weights (see Point 9.1.4). Each
roof extension can take a max. of 2 x 18 ballast weights.
The localized pressure on the roof surface can be minimized by setting the beam on wooden planks or
U-profiles. (U-profiles with holders for the wheels of the roof extension can be acquired as
accessories.)
The roof extensions must be set up horizontally and secured against rolling off (secure with wheel
brake or use additional wedges on sloping roofs of approx. ±3°). For roofs with greater sloping
inclinations, the roof extensions must be additionally secured and/or underpinned and horizontally
aligned.
The distance of the roof extension must correspond to the distance of the C-clamp or the front
suspension of the winch.
Always use personal protective gear (e.g. safety harness and
safety belt) when working at sites where there is a risk of
falling)
Hang up rope, see Point 9.1.5

The counterweights should be secured against unauthorized
removal by a padlock (1) (see picture).

9.1.2 Beam types and their assembly
The roof extensions can be built in 3 designs:
Roof extension DA (1) (basic variation, the beam lies on the fascia)
Only possible with AB 450 winch
The roof extension consists of:
Front beam [10]
Attachment support [20]
Connecting piece [30]
Rear beam [40]
Counterweight support with wheels
[50]
Locking pins
•Insert front beam and connecting
piece into each other to a degree
depending on the length of the
ballast arm and secure with pins.
(Number of necessary locking pins = 6)
•Push rear beam onto the connecting piece and likewise
secure with pins.
•Push counterweight support onto the rear beam and secure
with two pins. The distance L2 can now be adjusted (see
picture).
•Set attachment support on front beam and secure with two
pins. The distance L1 can now be adjusted.
