Fault

Motar spraying
machine does not
start

Mortar spraying
machine cannot turn
pump screw.

Mortar spraying
machine cannot be
switched on/off by
means of the remote
control.

Mortar spraying
machine builds up
pressure in the mortar
hose. However, no
coating material
comes out of the
spray lance.

The spray jet stops
while spraying,

"

spluttering

"

 occurs.

Coating material
suddenly stops
coming out while
spraying.

No clean, even
spraying pattern.

Possible cause

The mortar spraying machine has been
overloaded.

Pump screw is stuck in pump jacket.
Pump was not lubricated with pump 
antiseize.

Remote control not on.

Remote control line not connected or
defect.

Coating material "blockages" in mortar
hose. Motor hose not pre-rinsed with
synthetic resin dispersion or cellulose paste.

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 impurities
in the coating material or too large grain
size.
 

Air channels in the texture nozzle are
partially blocked with coating material.

Remedy

Set master switch and changeover switch to
„0“.
Turn mortar spraying machine back on after
about 10 sec.

Caution:

 set changeover switch to „0“

before turning on master switch.

Set delivery rate switch to “0”. Set
changeover switch to                (forward).
As soon as the pump screw rotates at a
constant speed, slowly set the delivery rate
switch to the desired delivery rate.

Set changeover switch to "AUTO".

Connect remote control, check
connections, check remote control line for
damage.

Find blockage by feeling the mortar hose.
Remove pressure from mortar hose  set
changeover switch to                (backwards).

Pump coating material back into receptacle.

Mortar hose must be without pressure.

Observe pressure gauge ––> 0
bar.
Wear protective goggles.

Disconnect mortar hose – bend the blocked
area by hand. Rinse mortar hose with a
water hose. When the blockage has been
removed, fill the mortar hose with synthetic
resin dispersion or cellulose paste. Re-
connect mortar hose.

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 coating 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.
