Preliminary Checks; Important - IMER BOOSTER 15 Manuel D'utilisation Et D'entretien

12. PRELIMINARY CHECKS

Before operating the machine, check the engine oil, radiator cool-
ant, hydraulic fluid and diesel levels.
Check that the safety grill (Fig. 18 Ref. 1) on the hopper is securely
mounted, that the opening safety device is operational (Fig. 18
Ref. 2), and that the outlet is closed and locked (Fig. 3 Ref. 1).
Check that the upper hopper is closed and its nuts fully tightened
down (Fig. 18 Ref. 3).
Check that the lubricant tank (Fig. 18 Ref. 4) is filled with water, top
it up if necessary: not doing so quickly leads to serious damage to
the pumping pistons.

- IMPORTANT: at low temperatures the water in the lubri-
cant tank may freeze and thus damage the sensor mount grill
and the sensors themselves.
If there is any danger of this occurring, open the cap (Fig. 4 Ref. 5)
to drain the tank.
- The casing must be locked.
- Before starting the machine, make sure that no unauthor-
ised persons are closer than 2 m or within the radius of
action of the final pipe.
- Check that the emergency button is operational.
13. STARTING UP
Prepare a suitable quantity of grout.
Pumping up to 20 metres: 40-50 litres
Pumping more than 20 metres: 50-80 litres
Pour the grout into the tank:
Make sure the levers of the distributor (Fig. 19, Ref. 2-3) are all in
the middle position.
Make sure the emergency button is not pressed (Fig. 19, Ref. 1)
and release it if necessary.
Check that the switch (Fig. 19 Ref. 4) is in the LOC position, to
enable the local controls. Turn the selector (Fig. 19 Ref.5) to ON,
wait for the spark plug indicator light (Fig. 19 Ref. 6) to switch off
and then turn the switch to START (Fig. 19 Ref. 5): the Diesel
engine starts.
Turn the switch (Fig. 19 Ref. 7) to the right (arrow upwards): the
machine starts to pump. Use the flow switch (+/-) (Fig. 19 Ref. 8)
to adjust the flow rate as shown on the LED indicator bar (Fig. 21).
The flow rate can be set to twenty different positions, which repre-
sent the following percentages of the maximum flow rate (Fig. 21).
Otherwise the machine can be started using the electric remote
control, by setting the selector (Fig. 19 Ref. 4) to REM which
enables the remote control.
With the switch (Fig. 19 Ref. 4) set to REM, the machine is control-
led exclusively by means of the electric remote control. Depending
on the machine configuration, wait until the grout in the hopper
reaches the level of the mixer, or until the product no longer comes
out of the pipe. At this point shut down the machine with the
electric control, fill the hopper and start working. Adjust the quantity
of material delivered from the pipe or jet with pushbuttons (+) and
(-) (Fig. 19 Ref. 8).
The machine can be equipped with a set accelerant pump which
can operate either manually or automatically. To enable manual

operation, turn the switch (Fig. 20) to the right and hold it there for
3 seconds, then release it; the led for the selected function will light
up. In manual mode, the pump runs at maximum speed.
To enable automatic operation, turn the switch (Fig. 20) to the
left and hold it there for 3 seconds, then release it; the function
light lights up and the led indicator bar (Fig. 21) on the control
panel starts to flash to indicate the previous setting. To increase/
decrease the percentage of accelerant, use the switch (Fig. 20)
in small steps to the right/left respectively. If you do not operate
the switch for a few seconds, the led indicator bar (Fig. 21) stops
flashing and the previously set percentage is stored. The speed
of the accelerant pump is a function of the flow rate of the pistons
and the percentage set on the led bar. To deactivate manual
or automatic operation, turn the switch to the same position to
which it is set for a few seconds and release it. The accelerant
percentage is in the range of 1 to 5% of the weight of cement. The
pressure gauge (Fig. 19, Ref. 9) indicates the pressure of the S
valve's hydraulic circuit; it will rise to 160 bar in case of blockage.
Try operating the mixer with the distributor lever (Fig. 19 Ref. 2):
with the top lever the mixer turns correctly; with the bottom lever
it turns in the other direction. The pressure gauge (Fig. 19, Ref.
10) indicates the pressure of the mixer's hydraulic circuit; it will
rise to 140 bar in case of blockage. The RH (shorter) lever of the
distributor (Fig. 19, Ref. 3) is used for operating the hydraulically
controlled pressure water cleaner: it must be in the middle position
when the pressure water cleaner hoses are not connected to the
water supply. Otherwise the pressure water cleaner will quickly
become permanently damaged
In case of an emergency, press the red emergency button (Fig 19,
Ref. 1) to stop the machine. The BOOSTER 15 is also equipped
with throttle lever to
adjust the Diesel engine speed from 2400 to 2700 RPM.
