MALFUNCTION POSSIBLE CAUSE ELIMINATION
Coating material is suddenly
not emitted during spraying.
Tip is clogged because of impurity in
the coating material or because the
granular size is too large.
Texture tip too small.
Coating material “plug” in the high
pressure hose.
Container empty (pump has sucked
in air)
Switch the machine off.
Secure the trigger guard on the spray gun.
Remove the tip and clean it.
Select a larger tip.
Depressurize the high pressure hose – set the se-
lector switch to “R” (reverse).
Pump the coating material back into the contain-
er.
The high pressure hose must be
pressureless.
Watch the manometer ––> 0 bar.
Wear safety goggles.
Decouple high pressure hose and rinse with water
hose. Couple the high pressure hose back on.
Take care to ensure that there is always sufficient
material in the container since even short periods
of dry running can lead to damage to the rotor /
stator. Refill the container and restart the machine.
When work continues, it may take a few moments
until the material comes out evenly again.
Uneven spray pattern. Machine poorly cleaned
No coating material in the container.
Pump has sucked in air.
Nozzle too small for the material being
used.
Thoroughly clean machine
Refill the container with coating material and
pump it around until the coating material emerg-
es without any bubbles.
Use a larger nozzle
Pressure at the manometer rises
to more than 120 bars.
Pressure sensor faulty
Please contact Wagner Service
Machine does not pump
enough coating material.
Pressure set too low.
High pressure hose diameter too small.
Stator and rotor worn.
Nozzle size too small for the material
being processed
Increase the pressure with the pressure regulator.
Use a high pressure hose with a larger diameter.
Replace the stator and rotor (Art. No. 2395996, see
Section 9.4)
Select a larger tip.
