3. CLEAN CONCRETE PUMP
WARNING
The following must be observed.
- Do not remove the grid from the
concrete filling hopper or enter the grid.
- Do not reach into the machine whilst the
drive motor is running or pressure
accumulator is charging, or keep objects
in openings.
DANGER
Danger to life by electric shock!
-
- Do not direct water jets or the jet of a
pressure cleaner towards the electrical
components of the machine.
* In the "CE" equipment, an end limit switch
stops the concrete pump and agitator when
the grid is opened.
This is not an EMERGENCY STOP function!
The interrupted functions restart after closing
the grid.
3.1 SECURE MACHINE
- Remove the remote control cable.
- Connect the radio remote control
transmitter.
- Use the local control.
WARNING
If the machine has to be switched on for
cleaning, the machinist is responsible that no
unauthorised persons come near the open
gate valve housing.
3.2 INSIDE CLEANING
- Have the drip pan for concrete residue
ready before beginning cleaning.
- Remove the tapered tube from the pipeline
outlet of the stationary concrete pump or
remove the pipeline outlet from the boom of
the truck-mounted concrete pump by
pivoting it to the side and securing it with
wedge 2 (Fig.: 17).
- Start up the concrete pump at the lowest
stroke rate, in order to pump any residual
concrete out of the hopper.
- Discard the residual concrete if you are no
longer able to use it at the construction site.
- Connect the water hose and hose out the
filling hopper (Fig.: 16).
The concrete pump sucks in water and cleans
the pumping cylinders.
- Switch off the concrete pump and the
vehicle engine!
