28. Loosen and remove the screw on the protective screen
of the material hopper.
29. To clean the star feeder, first remove the guard plate.
30. Pull the star feeder off the centring cone.
31. Clean the material hopper and the star feeder and loos-
en any adhering dry material with a scraper. Alterna-
tively, you can clean with water. In this case, dry the
material hopper and star feeder carefully. Remove the
cleaning residues through the cleaning opening at the
bottom of the material hopper and catch them with a
suitable container.
Cleaning opening on the lower side of the material hop-
per. It is closed with a disc and fixed with an eyebolt.
32. Replace the cleaned star feeder and close the protective
grating on the material hopper.
33. Open the drain taps located on the pressure reducer
and the flow indicator to drain the water fitting.

DANGER
Rotating mixing shafts.
Danger of death due to being pulled into the ma-
chine and crushed.
When the motor is running, the mixing shaft rotates
in the mixing zone!
• Do not reach into the rotating mixing shaft.
• Do not place any objects into the rotating mixing shaft.
1. Before working on the metering and mixing shaft, inter-
rupt the external power supply (main switch off). Loos-
en the screw of the protective screen above the material
hopper only when the machine is switched off.
2. Pull out the mains plug.
3. Secure the machine against unexpectedly being switched
back on.

DANGER
Pressurised conveyor hoses.
Risk of injury and risk of property damage due to es-
caping and/or flying material, and/or bursting con-
veyor hoses.
• Before disconnecting the conveyor hoses, make sure that
the hoses are depressurised. To do so, check the pressure
indicator on the mortar pressure gauge. The pressure in-
dicator must display 0 bar!
• Before opening the hose coupling, let the
inoCOMB Maxi Power run in reverse to reduce any pres-
sure!
• Use only conveyor hoses which are permissible with an
operating pressure of 40 bar, and are in a technically
perfect condition (e.g. are without any cracks or other
external damage!).
!
WARNING
Water jet.
Risk of injury and risk of property damage due to es-
caping water.
1. Interrupt the external water supply by closing the water
valve.
2. In order to release the pressure (approx. 2 bar), open
the water drainage valve on the water measuring sys-
tem under the pressure reducer.
3. Only remove the hose from the external water supply
when the pressure gauge shows “0” bar.
4. Do not point the water jet at other people or yourself.
10.2 After cleaning
NOTE
Note the optimum assembly sequence.
1. Assemble the pump unit (rotor/stator/pressure gauge/
pressure flange) with both tie rods at the lower end
of the green mixing zone. For easier installation, the
complete mixing zone incl. motor can be placed at an
angle.
2. Open the eccentric lock on the motor and move it
away to the side. Push the mixing coil into the mixing
zone. Then move the motor back again and close the
eccentric lock. Ensure that the mixing coil is connected
to the motor and rotor of the pump unit via the motor
bracket.
3. Connect the input socket to the external power supply
(400 V / 32 Hz)
