10 Cleaning & decommissioning
10.1 Cleaning process
1. Stop filling with bagged goods in sufficient time. Turn
the star feeder switch to “0” and continue spraying
until only water comes out of the sprayer and the pres-
sure indicator on the mortar pressure gauge shows 0
(zero). Catch the escaping residual material in a suitable
container.
2. Close the air valve on the spray head.
3. Close the ball valve on the spray head.
4. Open the screw connection on the spray head and re-
move the nozzle.
5. Clean the nozzle with a sponge or a cleaning brush.
6. Uncouple the now depressurised mortar hose from the
pump unit of the mixing pump and put a sponge ball
into the hose.
7. Connect the hose to the left-hand GEKA coupling of
the water fitting by means of a coupling reducer, and
open the ball valve and the ball valve on the spray head.
8. The sponge ball is carried through the material hose by
the water and removes any adhering residual material
from the walls of the material hose.
9. Once the sponge ball has emerged from the spray
head, close the ball valve on the spray head and the
mini ball valve on the water fitting.
10. Repeat the cleaning process with the sponge ball up to
twice depending on how dirty the machine is.
11. Insert the cleaned nozzle back into the spray head and
close the screw connection.
12. Switch off the mixing pump. To do this, turn the main
switch to the horizontal position “0”.
13. Pull out the mains plug.
14. To clean the mixing zone, open the side lock of the
tilting flange (1) and fold the motor away to the side.
15. Remove the mixing coil (2) from the mixing zone and
clean it.
16. Place the mixing tube cleaner (3) in the mixing zone
and turn it until it clicks into place. Make sure that the
coupling (4) of the mixing tube cleaner corresponds to
the position of the material claw (5) of the pump motor.
17. Fold the motor back onto the mixing zone and lock the
side tilting flange.
18. Switch on the machine for approx. 30 seconds to start
the cleaning process of the mixing zone.
19. Open the lateral locking of the tilting flange and fold
the motor away to the side.
20. Remove the mixing tube cleaner from the mixing zone.
21. Clean the inside walls of the mixing zone by hand and
rinse with water.

NOTE
In the event of a power failure, you can
also clean the mixing zone manually. To do this, insert
the mixing tube cleaner into the mixing zone and turn
it manually.
NOTE
Make sure that no water enters the dry
area between the mixing zone and the material hop-
per. The dust inside could clump and cause jamming
when the machine is started up again.
22. To clean the pump unit (rotor/stator), fill the mixing
zone with clean water and start the machine with the
star feeder switched off.
23. Switch off the mixing pump. To do this, turn the main
switch to the horizontal position “0”.
24. Then screw the rotor out of the stator and store it in a
dry location after cleaning.
25. Before reassembly, coat both the rotor and the stator
generously with assembly spray lubricant (item no.
10004591) in order to make it easier to screw the ro-
tor into the stator. Ensure that the rotor is correctly in-
stalled in the stator.
26. Put the mixing coil back into the mixing zone. Make
sure that the coupling of the mixing coil corresponds
to the position of the material claw of the pump motor.
27. Fold the motor back onto the mixing zone and lock the
side tilting flange.
