10.2 WATER CONNECTION (see fig. 1)
Connect the water hose (table 1) to the water mains.
-perform air purge through appropriate valve before each start
-the maximum water pressure must not exceed 5 bar
-With a mixer without water pump, the water supply must have a mini-
mum flow rate of at least 20 l / min and a minimum pressure of 2 bar.
-With a water pump mixer if the pump is not fed by water, the sealing
gasket burns.
11. START-UP
- During work start and stop the mixer exclusively by
means of the ON/OFF buttons.
- Load the pre-mixed dry material. Take the bags of material and
place them securely on the bag splitter grid (ref.10,fig.1), lift the
two end corners of the bag to completely empty the contents into
the hopper (fig.6).
- At this point position a suitable container below the material
outlet and start up the mixer by means of the ON/OFF switch.
The machine should now be in operation
To obtain the required material consistency:
Optimise the quantity of the water delivered by means of the valve,
while the mixer is in operation.
Make small adjustments of approx. 1/2 turn, every 15 seconds.
The machine is fitted with protection against power failure: if this
occurs, press the ON button to resume operation.
To stop the machine in the event of an emergency, press the red
button (OFF); all moving parts are shut down. Then disconnect
the plug from the power mains.
THERMAL CUTOUT PROTECTION:
- The electric motor is protected against overload by a
thermal cutout, the activation of which is indicated by total
shutdown of the machine. In this case, authorised personnel
should wait for the motors to cool and restart the unit by
means of the ON/OFF switch.
12. OPERATION
- The hopper safety grid must always be fitted.
The safety grille of the hopper is fixed by tightening the screw
(ref. 2) in the grille support (ref. 1) to which the grille is attached.
The screw (ref. 2) is held captive by the stop ring (ref. 3), so the grille
support (ref.1) remains permanently attached to the grille structure.
- Wear envisaged personal protection devices before
starting work.
12.1 Pauses during work
Interruptions exceeding 30 min should be avoided.
Prolonged shutdown can cause clogging in the mixing chamber
If no material exits the discharge outlet, this must be cleaned.
Stop the machine, proceed as described in para. 14, refit and
restart the unit.

13. MIXER CLEANING AND SHUTDOWN (see fig. 4)
At the end of the work shift turn off the machine by means of the
ON/OFF switch.
Remove the mixing chamber (ref.1) by turning it to release the
relative hooks (ref.2), together with the shaft (ref.3).
Empty and clean the mixing chamber and mixer with water and
dry both with paper.
Refit the shaft in its seat after ensuring that it is clean, then insert
the mixing chamber and hook up correctly.
At this point, on completion of machine cleaning, turn off the main
switch, disconnect the power plug, close the water delivery valve,
open the auxiliary valve and detach the delivery hose.
Before restarting the machine, ensure that all valves are closed
again.
If the machine is not to be used for several days, empty the hopper
completely.
- Caution! Before disassembling the mixer or removing
the grid, ensure that the main switch is set to OFF and the
plug is disconnected from the power supply.
14. MAINTENANCE (see fig. 1)
- Maintenance must be performed by adequately trained
personnel, after switching off the machine, disconnecting it
from the power supply and emptying the hopper.
Check daily that the water filter (table 2, ref.14) is clean.
Check weekly that the mixer shaft (ref. 8) is in good condition and
replace if necessary
Check weekly that the electric motors are free of dust and dirt and
if necessary clean using compressed air.
Check weekly that the plug and socket contacts are clean, dry
and rust free.
Every six months arrange for an inspection of the machine by an
authorised IMER service centre.
- Spent oil is a special waste. Therefore it must be disposed
of according to current legislation.
- Always keep notices and symbols on the machine legible.
15 SILICA DUST WARNING
Grinding/cutting/drilling of masonry, concrete, metal and other materials
with silica in their composition my give off dut or mists cintainig crystalli-
ne silica. Silica is a basic component of sand, quartz, brick clay, granite
and numerous other minerals and rocks. Repeated and/or substantial
inhalation of airborne crystalline silica can cause serious or fatal respira-
tory diseases, including silicosis. In addition, California and some other
authorities have listed respirable crystallinesilica as a substance known
to cause cancer. Whwn cutting such materials, always follow respiratory
precautions.
Use appropriate NIOSH-approved respiratory protection where dust
hazard may occur. Paper masks or surgical masks without a NIOSH
approval number are not recommended because they do little to protect
the worker. For more information about respirator programs, including
what respirators have received NIOSH approval as safe and effective,
please visit the NIOSH website at:
http://www.cdc.gov/niosh/topics/respirators
Observe OSHA regulations for respirator use (29 C:F.R. § 1910.134).
