Fault Cause Remedy
Machine does not start via
wireless remote control. Insufficient pressure gradient in
remote control due to blocked air
pipe or air nozzle tube. Check if air pipe is blocked.
Clean air nozzle tube.
Machine does not start. Too much hardened material in
hopper or mixing area. WARNING!
Turn off main switch and pull
out plug first.
Half-empty hopper and restart
or clean entire hopper and
mixing area.
Machine does not start. Hardened material is blocking the
rotor/stator pump unit. WARNING!
Turn off main switch and pull
out plug first.
Remove pump and install new
pump.
No material flow. Bad mixture in mixing tube. Add more water.
Deviations in filler
consistency (material flow
“thin-thick”). Material clogs, narrowing the
mixing tube inlet. The mixing shaft
or pump might be worn out. Clean mixing shaft, mixing area
and pressure flange. Inspect
mixing shaft and pump
components. Replace if
necessary.
Deviations in filler
consistency (mortar flow
“thin-thick”). Pressure reducing valve
misadjusted or defective. Increase water supply by 10 %
for approx. ½ minute and then
turn back slowly. Reset
pressure reducing valve to
factory setting.
Water level rises in mixing
tube during operation. Backpressure in material hose
higher than pump pressure. Check spray gun or material
hose for blockages and clean.
Warning! Wear protective
clothing, goggles etc.
