5.6 Function checks You should check the following functions before you begin using
5.6.1 Pump functions the machine on the construction site.

Switch over The fundamental prerequisite for problemĆfree use is a fully
functional pump.
Magnetic switches
Check for an unimpeded switchover function of the delivery pistons
and the transfer tube at various engine speeds and positions of the
output controller.

BP07_595_0912EN 1

Checking the magnetic switches

Check that the drive cylinders switch over automatically once the
hydraulic pistons are close to the magnetic switches. The green
inĆservice lamp on the distributor casing must remain lit during this
process. The yellow LEDs will light up briefly as soon as the hydrauĆ
lic piston approaches its magnetic switch. If one of the LEDs does
not light up, the associated magnetic switch is defective.

Stroke time delivery piston speed.
The delivery pistons move to their end positions. Stroke correction is
automatic and is complete when both delivery pistons come to a halt
(may be seen in the water box).

Measure the machine stroke time under no load, i.e. without
concrete.

" Set the engine to maximum speed.

" Set the maximum pumping rate.

" Start the measurement at the first switch over of the transfer
tube.
å The first single stroke is complete with the next transfer
tube switch over.

" Measure the stroke time over a period of ten single strokes.

The value measured, divided by ten, must match the data in the test
reading.

Note
Due to differences in reaction times when using the stopwatch, the
value determined may vary from the value stated by approximately
5%. You may have to take the measurement several times and
calculate the mean of the values measured.

Operation

5.6.2 Filter functions There are a number of filters in the machine’s hydraulic system.
The vacuum return flow filter is monitored by sensors. The display
shows whether the filter element needs to be replaced.

Dirty filters reduce the fluid flow considerably so that damage may
occur in the hydraulic system.

Note
Only the section return flow filter is monitored. Once the filter element
for the vacuum return flow filter needs replacing, the other filter eleĆ
ments must also be replaced.

Operation

Note
The warning indicator for the vacuum return flow filter turns red when
the oil temperature exceeds 25 _C and at the maximum engine
speed; the filter element must be replaced.

Danger
Risk of injury due to faults with the hydraulic fluid circuit. Unfiltered
hydraulic fluid causes faults with hydraulic components, leading the
machine to move unexpectedly. Ensure the machine is not run with
unfiltered hydraulic fluid.

Environmental protection
Comply with the waste disposal regulations in force for your area
when changing the fluid filter.

5ĂĊĂ64 BP07_817_1105EN

Operation

5.6.3 EMERGENCY STOP It is only possible to intervene rapidly in the event of danger if all the
function EMERGENCY STOP buttons are functioning.

Caution
The machine is no longer operating safely if one of the EMERGENCY
STOP buttons is defective, as you will no longer be able to switch the
machine off quickly enough if danger threatens.
You must therefore inspect the function of the EMERGENCY STOP
buttons and the lever position for the boom valves (see Function
check on the boom control block") before starting work each time.

Danger
The machine is only switched off electrically when the EMERGENCY
STOP button is pressed. Although this causes all the electrically
actuated hydraulic valves to be switched off, an unexpected sinking
of the boom caused by leaks in the hydraulic system, for instance,
cannot be prevented in this way.

In no event should you first press the EMERGENCY STOP button if
the boom starts unexpected movements. Should you do this you will
have no ability to counteract the movement.

Note
As soon as you release the boom control levers using the remote
control unit, the levers for the boom arm valves previously actuated
and for the operating mode selector valve must return to the central
position (zero position).

The reactions of the operating mode selector valve on the boom
control block are delayed by some 3Ăseconds if you use the cable
remote control.

BP07_818_1105EN 5ĂĊĂ67

Operation

5.6.5 Function check of the This machine is fitted with an agitator safety cutout (RSA). As soon
agitator safety cutout as you open the grille, the signal between the transponder and readĆ
ing head is broken. This causes the agitator to halt and the pressure
to be dumped from the accumulator, i.e. the transfer tube will no
longer be able to switch over. In addition, the delivery pistons return
to the end position and the concrete pump halts.

Danger
Risk of injury when the agitator is operating and the transfer tube is
switching.

A defective agitator safety cutout can cause you to believe that the
machine is safe, even though this is not really the case. This can
lead to the agitator continuing to run or the transfer tube switching
over when the grille is open.

You must therefore check the function of the agitator safety cutout
before you start each pumping job.

You must stop work if you open the grille, but
ć the agitator continues to run, or
ć the transfer tube continues to switch over, or
ć the concrete pump does not run to its end position.

Operation

5.7 Boom movements Before you unfold the placing boom you must have read the safety
regulations and completed the operations to set up the machine.

You may only unfold the placing boom once you have set the maĆ
chine up properly. Comply with the safety regulations of the country
in which you are using the machine in every case.

Prohibited activities

BP07_005_1406EN 1

Prohibited

Danger
Avoid the following actions. They overload the placing boom and will
lead to damage and jeopardize persons:
ć Lifting and transporting loads;
ć Allowing the placing boom to strike an obstacle;
ć Pushing with the placing boom, in order to move an obstacle out

of the way, for instance;
ć Tearing away a trapped end hose by force.

5ĂĊĂ70 BP07_005_1406EN

Operation

5.7.1 Restrictions on use Extreme weather conditions, such as gales, storms or low temperaĆ
tures restrict the use of the boom, or can even make its use impossĆ
Bad weather and ible.
storms
Shift the placing boom to the rest position in the event of storms and
bad weather.

– Placing booms with a vertical reach of 42 m or more may only be
operated in wind forces up Windstärke7 (wind
speed 51 km/h = 14 m/s).

– Placing booms with a vertical reach of less than 42 m may only be
operated in wind forces up to 8 (wind speed 74 km/h = 20 m/s).

Wind speeds in accordance with the Beaufort scale are average
wind speeds measured over a period of 10 minutes. Higher speed
gusts of wind may occur briefly during the measuring period.
Higher wind speeds jeopardize stability and safety of the structural
element. There is a risk of lightning strike in the event of storms.

Danger
There is a risk of fatal injury in the event of a lightning strike. The maĆ
chine and the surrounding area will be charged with electricity.
Earthing the machine does not reduce this risk. You should therefore
fold in the placing boom if there is a risk of lightning strike.

Tower cranes on construction sites generally have wind speed
measuring equipment, so that you can ask about the wind speed at
any time. If no wind speed measuring equipment is available, you
can ask the nearest meteorological office what the wind speed is, or
estimate the wind speed using the following rule of thumb.
− In winds of force Ă7 and greater, green leaves break from trees and

inconvenience is felt when walking against the wind.
− In winds of forceĂ8 and greater, small branches break from trees

and walking outside is significantly impeded.

BP07_005_1406EN 5ĂĊĂ71

Operation

Cold weather The boom must not be used in temperatures below minus 15 _C
5.7.2 Danger zone (+ 5 _F) unless the manufacturer has given express approval. There
is a danger of damage to the steel (brittle fracture) and the seals
throughout the system at such extreme minus temperatures.

In addition, such minus temperatures should be considered the realĆ
istic lower limit for concrete placement, as it is no longer possible to
prepare concrete such that it can achieve its strength without the use
of special additives.

22000500

The danger zone when working with the boom is the zone over
which the boom is slewed.

Falling itemsā
There is a risk of injury from parts of the delivery line falling beneath
the slewing circle of the placing boom. There is a risk of injury from
falling concrete beneath the end hose.
You should therefore secure the danger zone. Keep the danger zone
under constant observation.
You must cease working immediately and press the EMERGĆ
ENCY STOP button if unauthorized persons enter the danger zone.

Operation

High–voltage lines

BP07_005_1406EN 2

Caution in the vicinity of high−voltage lines

Danger
There is a risk of fatal injury if high−voltage lines are touched. The
machine and the surrounding area will be charged with electricity. A
spark can jump across from high−voltage lines even if you just apĆ
proach them and this will energize the machine and the surrounding
area. You must therefore always maintain the specified safe clearĆ
ance.

Operation

5.7.3 Spontaneous retrac- During operation, the hydraulic fluid can heat up to a temperature of
tion of the boom 60−70 °C.
cylinders and support When the hydraulic fluid cools, its volume reduces as cold hydraulic
cylinders fluid has a smaller volume than hot hydraulic fluid. This causes the
boom cylinders, swing−out cylinders, telescopic cylinders and supĆ
port cylinders to retract slightly. The boom and the machine may
lower, the telescopic and swinging support legs may retract or swing
in.

Danger
Retraction of the swing−out cylinders, telescopic cylinders and supĆ
port cylinders may cause the machine to tip over. This causes a
danger to life and limb to persons who remain in the area of the
boom. You must keep the supports under constant observation whilst
the machine is in operation. You may have to readjust the swing−out
cylinders, telescopic cylinders and support cylinders.

Caution
The boom can sink during lengthy pauses in work due to cooling of
the hydraulic fluid. Consequently, the boom may be damaged or
other objects may be damaged by the boom. For this reason, you
should never leave the boom unattended in the unfolded position
during breaks in working.

5ĂĊĂ76 BP07_005_1406EN

Operation

Loss of volume

BP07_005_1406EN 5

Note
The size of the change in volume in a hydraulic cylinder depends on
the extent to which the hydraulic cylinder has been extended and
the magnitude of the temperature difference in the hydraulic fluid.

BP07_005_1406EN 5ĂĊĂ77

Operation

5.7.4 Uncontrolled boom The following defects may be the cause of uncontrolled boom moveĆ
movements ments:
− Malfunction in the remote control circuit
− Malfunctions on the boom control block
− Lines, threaded unions or boom cylinders leaking
− Defective mono−isolator on the boom cylinder
− Hydraulic system not carefully bled
− Insufficient hydraulic fluid in the reservoir
− Cooling of the hydraulic fluid

In this case, the boom may move as soon as the remote control is
switched on. Halt work immediately. You can continue working only
after the causes have been remedied and perfect functioning of the
machine is ensured.

Note
Whatever the reason for the uncontrolled movements of the boom,
you must halt the work on site and have the cause of the breakdown
determined and rectified by qualified personnel.

Danger
In no event should you first press the EMERGENCY STOP button if
the boom starts unexpected movements. Should you do this you will
have no ability to counteract the movement.

5ĂĊĂ78 BP07_005_1406EN

Operation

Countermeasures You must proceed as follows if the boom starts uncontrolled moveĆ
ment:

" Counter the uncontrolled movement immediately and attempt
to steer the boom out of the danger zone and bring it to rest
under control.

If the uncontrolled boom movement continues, despite countermeaĆ
sures:

" Press the EMERGENCY STOP button.

Note
Repeated practice is required to ensure that it will be possible to imĆ
plement the measures described above in an emergency.

pump from overheating and other subsequent damage.

When draining the water box, check the condition of the water − parĆ
ticularly that it is clean.
ć A chalky white colour is a sign of cement in the water.

This is an indication of damaged delivery pistons.
ć An unusual amount of fluid in the water indicates that the drive cylĆ

inders are leaking.

Damage to the delivery pistons or drive cylinders must be rectified
immediately. Putzmeister accepts no warranty claims for damage to
the machine resulting from failure to properly observe the maintenĆ
ance regulations.

Operation

5.12 Pumping operations You must carry out the following procedures before you start to
5.12.1 Dangers pump:
− Set the machine up for work properly (see Setting up" section).
− Set the machine supports out properly (see Supporting the maĆ

chine" section).
− Carry out all necessary function checks (see Function checks"

section).
− Unfold the boom to the desired working position (see Unfolding

the placing boom" section).

Dangers to the life and limb of site personnel can arise at many
points during pumping operations. You can minimize these dangers
by observing the following notes.

Danger
The machine is at risk of toppling over if the gross weight of all fitĆ
tings (e.g. including the squeeze valve) at the boom tip including
concrete filling exceeds the maximum loadbearing capacity of the
placing boom.

The gross weight of all fittings at the boom tip including concrete fillĆ
ing must not exceed the maximum loadbearing capacity of the placĆ
ing boom.
As a result, you must only use the end hoses specified by the manuĆ
facturer in your machine documentation.

BP07_320_1111EN 5ĂĊĂ105

Operation

Danger
There is a risk of injury in the area around the end hose if the end
hose strikes out when starting to pump, after a blockage has been
freed or during cleaning. The diameter of this zone is twice the end
hose length.
The end hose must be allowed to hang freely.
Ensure that noĆone is standing in the danger zone. Keep the danger
zone under constant observation.
You must stop working immediately and press the EMERGENCY
STOP button if anyone enters the danger zone.
