Make sure you are completely familiar with the procedure for shut‐
ting down the machine in an emergency situation before you start
pumping.
If a malfunction occurs during the pumping process, consult the
“Faults, cause and remedy” chapter first. Contact the manufactur‐
er's After Sales department for advice if you are unable to rectify
the fault yourself.
Inspect the monitoring instruments continuously during the pumping
process:
1. Inspect the mortar pressure on the pressure gauge
2. Inspect the water volume on the flow meter
Repeat these checks regularly at short intervals during the entire
operating time of the machine.
6.7.1 Breaks in pumping
Breaks in pumping should be avoided as much as possible, as the
conveyed material can segregate or set in the delivery line. Observe
the binding time of the material.
WARNING
Risk of the delivery line bursting in case of a blockage
▶
Never pump segregated material or material that has become
lumpy because it is beginning to set into the delivery line. This
causes very small blockages to appear.
If breaks in operation are unavoidable, observe the following points:
1. Every interruption to the spraying process can cause slight irregu‐
larities in the consistency; however, these will return to normal on
their own. You should therefore not immediately adjust the water
supply in the event of an irregularity.
2. Never leave the delivery line under pressure.
