FOREWORD
Dear MAI customer!
We wish to congratulate you on your purchase of
the MAI m400NT mortar mixing pump. The MAI
pump m400NT is a fully automatic mortar mixing
pump for continuous processing of all kinds of ma-
chine-processable anchor mortar and building site
cement.
The pump is driven by one motor only. A rubber
screw in the mixer transports the dry anchor mortar
to the mixing chamber where it is continually mixed
with water.
The water can either be supplied direct if the pres-
sure is high enough or an optional water pump can
be fitted, if required.
Once the material is thoroughly mixed, the entire
amount is then drawn in and pumped away by the
clampless, maintenance-free screw pump.
The most important features of the MAI pump
m400NT are the high quality of the components
used, the user-friendly layout of the controls and the
rugged design which proves its worth, day in and
day out on demanding building site applications.
User-friendly
oSimple to service and dismantle thanks to the
modular design.
oClearly structured operating elements.
oEconomical.
oThe patented MAI mixing and pumping tech-
nology guarantees continuous blending of dry
material, uniform mixing ratio, constant mixing
quality and therefore adequate processing.
OPERATING INSTRUCTIONS
These operating instructions contain the most im-
portant directions for a safe operation of the ma-
chine. The manual should therefore always be kept
in the tool box so that it is at hand when required.
Please read the operating instructions carefully
before starting the machine to familiarize yourself
with its handling and trouble-free operation of the
machine.
A working knowledge of the basic safety regulations
and instructions is the prerequisite for safe handling
and trouble-free operation of the machine.
Every single person working with the machine must
not only observe the operating instructions and the
safety regulations in particular, but also the applica-
ble rules and regulations governing accident pre-
vention at the location.
POTENTIAL HAZARDS
The MAI pump m400NT is built to the state of the
art and in accordance with recognized safety regu-
lations.
If not used properly, the machine
can however constitute a danger
to life and limb for the operator or
third parties, or adversely affect
the machine or other material re-
sources
!
DANGER
The machine may only be operated for the pre-
scribed use and if it is in perfect condition conform-
ing to the safety regulations. Faults that could affect
safety must be remedied immediately.

DIRECTIONS BEFORE
START-UP
To guarantee trouble-free start-up, ensure that all
the components have been cleaned properly and
are in perfect condition. Check that the machine is
horizontal and stable so that it cannot slip if moved
accidentally.
Check that all the cables and safety devices are
functioning correctly.
Ensure that the machine is horizontal and standing
safely.
Check that all the components have been mounted
properly.

CONNECTIONS BEFORE
START-UP
Connect the main power plug on the control cabinet
with the cable to the construction site distribution
board.
Plug the drive motor into the socket on the control
cabinet.
Connect the water supply hose (use a minimum
diameter of ¾”) to the coupling in the water system.
START-UP Switch on the machine by turning the master switch
to position “I”.
Close all the water supply and drain valves.
The machine may only be con-
nected to a construction site distri-
bution board fitted with a residual
current-operated circuit breaker.
Electrical protection: 3x25 A distri-
bution board, rated fault current
I=30mA
!
DANGER
Connect the water supply hose (minimum diameter
¾” for 4 bar min. dynamic water pressure). Slowly
open the water supply cock.
Connect the ~3X400V/50Hz ~3X220V/60Hz power
supply with the electricity cable (use only 5x4 mm²
H07RN cable).
Press the blue “WATER INJECTION” button and
set the required water volume by turning the knob
on the needle valve.
The water pressure must be at least approximately
2,5 bar when the valve is open (dynamic). If this is
not the case, the machine cannot be started or
stops automatically if already in operation.
Set the mode switch “REMOTE C – HAND - IN-
JECTION” to the “HAND” position. (All controls,
such as switches, indicators, alarms and buttons
are illustrated on page 11 and 16).

MAI International
GmbH
Turn the mode switch “REMOTE-HAND-
INJECTION” to position “HAND”. The vibrator
switch must be set on “ON” to prevent the dry mate-
rial from bridging at the bottom of the material hop-
per.
Undo the eccentric clamp on the mixing chamber.
Open the pump outlet by turning it to the side to
drain the water which was just sprayed into the
mixing chamber.
Place machine processable dry material in the hop-
per.
Close the pump outlet again and lock the eccentric
clamp.
The safety screen must not be
removed when the machine is
running or ready for operation.
!
WARNING
Press the blue “WATER INJECTION” button for
approx. 3 seconds to let a defined water volume
into the mixing chamber of the mortar mixing pump.
This is to prevent the eccentric worm pump from
running dry when the machine starts.
Start the machine by pressing the green “START”
button. Let the mortar mixing pump run until water
starts to come out of the front of the pump outlet.
The mixer motor must not be
opened or tilted when the machine
is running or ready for operation
(as long as the power supply is
connected and/or the master
switch is set to “ON”).

To prevent chocking, we recommend wetting the
inside walls of the hose with water or preferably
lime or cement slurry.
1.)
2.)
3.)
During the wetting process with
water it is absolutely necessary
that any excess water is com-
pletely drained from the hose oth-
erwise grains could be washed out
when the machine is started, es-
pecially in the case of coarse grain
materials, such as anchor mortar
with 4 mm maximum grain. This
could cause the hose to choke.
After 10 – 15 seconds the mortar consistency
should have adjusted to the value pre-set on the
water flow meter and be coming out of the coupling
on the pump outlet pulsating slightly but uniformly.
The consistency of the mortar can be adjusted to
the required application by changing the water flow
rate.
Lay the mortar hose so that it can be easily con-
nected before the machine is started.
If you are working with unknown
materials, experience has proved
that it is better to start with a rela-
tively fluid consistency and then
slowly reduce the water volume
with the machine running until the
required consistency is reached
(unknown materials: water flow
meter setting: approx. 600 li-
tre/hour).
NOTE
i
Connect the quick release coupling on the mortar
hose to the male union on the pump outlet.
