7.5 STARTING THE MACHINE
- Package an adequate amount of grout (water and cement):
• pumping up to 20 m - 40/50 litres
• pumping beyond 20 m - 50/80 litres
- Check the emergency button (FIG.36-REF.1) is not engaged.
- Insert the ignition key and turn it to ON
The pre-heating phase starts automatically, once the key has been turned. The LED (FIG.35-REF.10) on the console indicating
spark plugs pre-heating switches on. Wait for this LED to switch off. Once the pre-heating phase has been completed:
- Press the activation button (FIG.35-REF.2); the motor starts running.
- Pour the slurry into the hopper.
- Press the button to start the mixer. The mixer's direction of rotation can be reversed.
Before starting the pumping, be sure that, in the zone of unloading of the material, this operation doesn't
create danger.
- Using the manual accelerator, accelerate the engine slightly up to bottom ramp and activate pumping by using the selector
switch (upwards); act on the accelerator lever again, if required.
Press the selector switch downwards key to suck the mix: the mix is sucked by piping and re-introduced in the hopper. To
return to the pumping phase, press the selector switch upwards.
- Rotate the adjustment hand wheel (FIG.36-REF.2) of the hydraulic pump to reach a value of 6 - 10 pumping/minute.
- If the "safety intervention" indicator switches on, it means the hopper safety grid is open and the grid safety device has
intervened: hydraulic supply is interrupted and the controls are disabled.
The operator must check the pumping circuit manometer during the first few pumping cycles, for best perception of relation
between the effective work pressure and the maximum pressure.
The effective work pressure (on hydraulic circuit oil) varies based on used mix and layout of the piping line. The manometer
indicates the hydraulic cylinders' working pressure during pumping. The manometer indicates the hydraulic jacks' (controlling
the S valve) working pressure during S valve exchange; the manometer indicates peak pressure for a brief moment, when
jacks reach end run.
When the pumping barrels' inlets and/or wear plate surface from the hopper full of grout, pour the concrete and start pumping
at low flow rate.
- Activate the electric vibrator of the grid.
Flow rate can be increased to wanted value using the flow rate regulator, when the first concrete reaches the piping line's
outfeed.
The auxiliary circuit manometer indicates the services' work pressure (mixer, optional high pressure water jet machine), that
must be below 180 bar. Should the mix be operating and manometer show 180bar pressure, check there is nothing in the
hopper preventing mixer rotation.
Remote controls
Insert the plug into the connector's socket located on the machine's bodywork (see par. 5.4.2), if using the remote control via
cable.
If machine is provided with radio control, connect it to the connector's socket (see par. 5.4.3).
The LOCAL/REMOTE selector switch allows selecting the pumping controls from the control board (local) or from a remote
device [remote control (standard) or radio control (optional)].
