Plast Coat 25 · 35
FAULT
The spray jet stops while spray-
ing, "spluttering" occurs.
Coating material suddenly stops
coming out while spraying.
No clean, even spraying pattern. Air channels in the texture nozzle are
Pressure on the pressure gauge
increases to over 40 bar.
Mortar spraying machine does
not transport sufficient coating
material.
If none of the above-mentioned possible causes was the reason for malfunction, there must be a defect which will be repaired
by the WAGNER after-sales service.
POSSIBLE CAUSE
No coating material in receptacle.
Pump has sucked up air.
Coating material is not sliding down in
the receptacle.
Blockage in texture nozzle due to im-
purities in the coating material or too
large grain size.
partially blocked with coating material.
Viscosity of the coating material too
high.
Mortar hose diameter too narrow.
Mortar hose too long.
Flow speed selected too low.
Mortar hose diameter too narrow.
Pump jacket worn.
Viscosity of the coating material too
high.
Texture nozzle too small.
REMEDY
Fill with coating material and pump in circulation
until coating material is free of bubbles.
Caution:
Do not allow the pump to run dry. The pump
will heat up, thus danger of "blockage". Refill
with coating material.
In all cases turn off mortar spraying machine (see
safety requirements) – then push down the coat-
ing material.
Turn off mortar spraying machine. Close the
material tap on the spray lance. Remove texture
nozzle and clean. If necessary, use larger texture
nozzle. Rule of thumb:
Grain size x 3 ––> Nozzle size.
Turn off mortar spraying machine.
Close material tap on spray lance.
Remove texture nozzle. Clean air channels in the
texture nozzle.
Dilute the coating material.
Use a mortar hose with a larger diameter.
Use shorter mortar hose.
Set feed rate to a higher setting.
Use a mortar hose with a larger diameter.
Install new pump jacket and, if necessary, new
pump screw.
Caution: Spray with pump antiseize.
Dilute coating material.
Select a larger texture nozzle.
