ELIMINATING FAULTS
PowrMax
MALFUNCTION
POSSIBLE CAUSE
ELIMINATION
Coating material is suddenly
not emitted during spraying.
Texture 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 mortar
hose. Mortar hose not prerinsed with
cellulose paste.
No coating material in the container.
Pump has sucked in air.
Switch the mortar spraying machine off.
Close the material cock at the spray lance.
Remove the texture tip and clean it.
Select a larger texture tip.
Rule of thumb: Granular size x 3 ––> Tip size
Depressurize the mortar hose – set the selector switch
to “R” (reverse).
Pump the coating material back into the container.
The mortar hose must be pressureless.
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.
Refill the container with coating material and pump
it around until the coating material emerges without
any bubbles.
Attention:
Always top up with sufficient coating material.
Do not let the pump run dry. Pump overheats, re-
sulting in a danger of „plugs“.
Spray pattern is not clean and
even.
Air ducts in the texture tip are partially
closed with coating material.
Air volume incorrectly set.
Poor mortar spraying machine
cleaning
No coating material in the container.
Pump has sucked in air.
Switch the mortar spraying machine off.
Close the material tap at the spray lance.
Remove the texture tip. Clean the air ducts of the
texture tip.
Change air volume setting.
Thoroughly clean mortar spraying machine
Refill the container with coating material and pump
it around until the coating material emerges without
any bubbles.
Attention:
Always top up with sufficient coating material.
Do not let the pump run dry. Pump overheats,
resulting in a danger of „plugs“.
