Dilute the coating material.
Use a mortar hose with a larger diameter.
Use a shorter mortar hose.
Depressurize the mortar hose – set the selector
switch to "R" (reverse).
Pump the coating material back into the con-
tainer.
the mortar hose must be pres-
sureless.
Watch the manometer ––> 0 bar.
Wear safety goggles.
Decouple mortar hose and rinse with water hose.
When the plug has been removed, fill cellulose
paste in the mortar hose. Couple the mortar hose
back on.
Set the volume regulator higher.
Use a mortar hose with a larger diameter.
Mount a new stator, if necessary, also a new rotor.
Attention: Spray on pump sliding means.
Select a larger texture tip.
Rule of thumb: Granular size x 3 ––> Tip size
Stop work immediately because otherwise coat-
ing material may enter the drive and result in a
defect.
Clean machine and contact Wagner customer
