BP21_782_1412EN 1

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.

3ĂĊĂ128 BP21_782_1412EN

General technical description

The spirit levels are fitted in such a way that, when supporting the
machine, you can easily check the horizontal alignment of the maĆ
chine. In the event of damage to the spirit levels or their brackets, it
cannot be guaranteed that you can set up the machine so that it is
horizontal.

For this reason, check both spirit levels and their brackets for visible
damage daily. Have any damage rectified immediately by
Putzmeister qualified personnel. Damage has also occurred if the
displays in the two spirit levels differ.

Furthermore, the spirit levels must undergo an annual inspection.
The result of the inspection must be documented in the check book
and confirmed by the inspector.

radiator of the hydraulic fluid in the machine first flows through this hydraulic
fluid radiator before it returns to the filter. The fans on the hydraulic
fluid radiator can be switched on by twoĂtemperature sensors or
manually.
− A 70Ă_C temperature sensor is fitted on the hydraulic fluid radiator.

This temperature sensor measures the temperature of the
collected boom return fluid, agitator return oil and flushing fluid.
− The second temperature sensor is mounted in the leakage oil line
of the main hydraulic pump. This temperature sensor measures
the temperature of the leakage oil for the main hydraulic pump
and has switching values of 55 _C, 85 _C and 90 _C.

General technical description

Special features of the hydraulic fluid radiator control system

This circuit offers both a redundant safety system and cooling of the
hydraulic fluid if only the boom is being moved or only the concrete
pump is running.
− Initially, one of the two fans on the hydraulic fluid radiator switches

on once the leakage oil from the main hydraulic pump reaches a
temperature of 55 _C.
− If the hydraulic fluid from the cooler reaches a temperature of
70 _C, both fans switch on.
− If the main hydraulic pump leakage oil reaches a temperature of
85 _C, the output is reduced gradually.
− If the main hydraulic pump leakage oil reaches a temperature of
90 _C, the concrete pump switches off.

Note
You may switch on both fans at the same time at the control cabinet,
whatever the fluid temperature, should you wish to cool the hydraulic
fluid before it has reached 55 _C or 70 _C as a precautionary meaĆ
sure. As soon as one of the two fans begins running, this is shown
on the control cabinet.

For optimal operation of the machine, the temperature of the
hydraulic fluid should not drop below 40 _C.

Leave the truck engine running during breaks in pumping or when
pumping is completed until the fan motors switch themselves off.

The hydraulic fluid is also cooled by the water in the water box.
The hydraulic fluid warms up the piston rods for the drive cylinders.
These are flushed, and thus cooled, by the water in the water box
on each stroke movement. This also cools the hydraulic fluid.
You should therefore change the water in the water box at frequent
intervals.
