Chapter 2 Safety
2.2 General risk sources
!
DANGER
Electrical voltage.
Danger of death due to electric shock.
• Work on the electronic control system may only be per-
formed by a qualified electrician.
• Connect the mixing pump only to regulation construc-
tion site power distribution points with FI circuit breakers
(30 mA).
• The connection must be fused with 25 A.
• The cross-section of the supply cable is at least 4.0 mm
2
at 400 V 3 PH
• Connect the supply cable to the feed-in connector of the
switching cabinet.
• All operating equipment on the construction site must
generally be connected according to BGI/GUV-I 608.
!
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).
2. Pull out the mains plug.
3. Secure the machine against unexpectedly being switched
back on.
4. Open the eccentric lock on the motor and move it away
to the side.

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! To do this, turn the phase-change switch (1) until
the red illuminated button on the machine’s switching
cabinet (2) lights up. Then press the red illuminated but-
ton. The pump then runs backwards.

• Use only conveyor hoses which are permissible with an
operating pressure of 40 bar and a burst pressure of 120
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.
2.2.1 Notices in the operating manual
!
CAUTION
Safety notices in the operating manual
alert the operating personnel to any immediate dan-
ger. Please observe all the technical and hazard notic-
es in this operating manual.
2.2.2 Performing checks before starting work
!
WARNING
Defects or damage can put the safety of
operating personnel at risk and impair the functional-
ity of the machine.
• Before commencing work, check the machine for any
obvious external damage or defects.
• Do not commission the machine if you notice any dam-
age to or defects in the machine or to the conveyor hos-
es.
• Ensure that the damage and/or defects are rectified.
