Operation

5.1.4 Remote control Depending on your machine’s equipment, you can operate it
− with the radio remote control,
− with the cable remote control or
− directly on the machine in emergency operation.

Caution
Carry the remote control in such a way that no control elements
can be actuated unintentionally. Do not damage the remote control
cable. Malfunctions may otherwise occur.
Never put the remote control down when the machine is ready for
operation. If this is unavoidable in exceptional cases, you must
switch off the remote control, disconnect it and lock it away.

Danger
Risk to life from unintended machine movements. The range of
a radio remote control is great enough for the machine to receive
control commands (e.g. from a great distance, from inside enclosed
spaces), even without visual contact. In such cases, signallers MUST
be used, and must remain in contact with the machine operator
using suitable means, and have visual contact with the site of
concrete placement, work and danger zones and the machine.

5.3 Set–up site Operation

As a rule, the site management determines the set−up site for the
machine and prepares the site accordingly.

Note
However, it is the machine operator who takes the responsibility for
setting up the machine safely.

Inspect the proposed site carefully and reject the set−up site if you
have any doubts on safety grounds. Ask the site management about
the permitted ground pressure.

" Walk the approach route before you drive it. Ask for someone
to give you directions if you have to reverse.

" Maintain a safe distance from pits, slopes, trenches, etc., when
approaching the set−up site and when setting up.

" Ensure that there is clearance to extend the support legs.
" Check the clearance for extending the placing boom.
" Ensure that the set−up site is adequately ventilated. Exhaust

gases can be fatal.

Danger of poisoning
Vehicle exhaust gases contain constituents which can be lethal or
carcinogenic. Set the machine up at an adequately ventilated site or
vent the exhaust gases away from where you are working.

Danger
On multiple telescoping support legs, the snaplock only locks the
outer support leg box and not the inner support leg. You should
therefore check after extending or retracting the support legs that
both the support leg box and the support leg are fully extended/reĆ
tracted.

Operation

Note
Extendible support legs are automatically locked by the snaplock
once the support leg is fully extended.
Replace the spring pin once the legs are locked. The snaplock canĆ
not now be opened unintentionally and the support leg remains
locked in the end position.

The snaplock has no function once swingĆout support legs have
been swung out. Do not replace the spring pin; in this way the supĆ
port legs will be locked automatically when they are swung back.

Before departure, make sure that all snaplocks are secured by a
spring pin.

5.4.5 Danger zone

12100300

The danger zone when setting out the machine supports is the
zone in which the support legs are swung out or extended.

Danger of crushing
There is a danger of crushing in the swingĆout and extension zone of
the support.
You should therefore secure the danger zone. Keep the danger zone
under constant observation.
You must halt work immediately and press the EMERGENCY STOP
button if anyone enters the danger zone.

Uncontrolled movements of the support legs increase the risk of
accident. They are possible if:
ć the hydraulic system has not been carefully bled;
ć lines or threaded unions are leaking;
ć there is insufficient hydraulic fluid in the reservoir;
ć the preselection switch is defective or dirty.

In this case, the support legs may move as soon as the preselection
switch is actuated.
Halt work immediately. You can continue working only after the
causes have been remedied and perfect functioning of the machine
is ensured.

5.4.6 Stability Operation

The gross weight of the machine determines the location of the
centre of gravity. The positions of the support legs define the tilting
edges. So that the machine is stable, the centre of gravity must alĆ
ways be within the tilting edges.

No. 0 Designation
1 Tilting edges
2 Possible centreĆofĆgravity line with a 360° rotation of the
placing boom

Danger
If the machine is not correctly supported, there is a risk to life, as the
machine may tip over.
To ensure stability, you must put the machine into normal operation,
ć extend/swing out the support legs as far as they will go
ć and lift the machine clear of the ground.
Thanks to our product observations, we have determined that during
operation, it is not rare to find the rear wheels remaining on the
ground. This allows you to achieve smoother pumping and a lower fill
height, but lessĆthanĆperfect stability during normal operation. Do not
swing the arm assembly towards the rear, as this does not ensure
stability.

Danger
Lethal danger due to the machine toppling over and risk of damage
to the machine.
Deviations from the horizontal greater than 3° may cause the maĆ
chine to fall over, the boom to swing unexpectedly and load−bearing
components to break, leading to the service life of the machine
being shortened.
ć Set the machine so that it is horizontal.
ć Observe the spirit level when extending the support feet.
ć Only execute the support functions one at a time.

Operation

5.5 Special case “One- Busy traffic conditions and lack of space on construction sites someĆ
Side-Support” times do not allow the support legs to be swung out or extended
fully. In special circumstances of this nature, you may set up the
machine with OneĆSideĆSupport" as described below.

Danger
This arrangement of supports should be the exception. Wherever
possible, you must set out the machine’s supports such that all supĆ
port legs are swung out and extended to their normal end position.

Follow the instructions precisely when using OneĆSideĆSupport" and
work with great care. As a precaution, use oversized timber blocks
beneath the support foot plates. This will prevent stability being addiĆ
tionally jeopardized by a support foot sinking.

Maintain the required distance from pits, slopes and similarĂ when
using OneĆSideĆSupport.
