Connect the machine to the general grounding system of the construction site by means of the power cable having a
resistance not above 883 ohm. If this values is exceeded, the machine must be connected to an additional ground rod, linking
it to the special ground screw (ground rod, see figure 2) and to a water source. Make sure there is an area of respect of at
least 1000 mm around the machine.
During working the machine produces dust as well as solid and liquid rejects, which must be disposed of by specialized
companies.

The use of the machine by unauthorized personnel is not allowed.
5.3
Areas of respect and dimensions
The areas of respect around the machine shall be at least 1000mm.
to ensure good working and correct maintenance of the machine. The personnel shall move within this area with
the utmost care. Within the area of respect there is the work area for the operator. The work area for the operator
shall be at least 2 square meters. The machine is equipped with feet and holes provided for the fixing to the
ground. Fixing to the ground shall be carried out by means of screw anchors and/or special screw nuts.
Inside the area of respect the operators shall move with the utmost care and eliminate all kinds of obstacles
hindering the passage. The ground may become slippery because of the work residuals. Use the protective
equipment (safety shoes) and frequently clean the ground. Caution! The use of products with additives may
injuries the health. Carefully read the prescriptions of the product.
These products may also modify the quality of the
paint of the concrete mixer and damage its hydraulic parts.
Inside the work area of the machine provide hoisting means for the material to be used (cement) and the mixed material.
In case of voluminous products, make sure there are no interferences with the machine and the perimeter protections.
Ensure
good lightening inside the work area, in order to avoid shady areas, dangerous dazzling and stroboscopic effects.
5.4
Assembling the machine.
Use work gloves
during assembling and/or replacing the machine components.
Completely assemble the machine, in the French type version, by simply positioning it at the desired height by
means of the holes on the legs. Check the machine for possible damages during transport. Before doing this, cut off the
power supply to the machine.
5.5
Electric installation
The electric installation of the user must be in compliance with CEI 64.8,
Italian law n. 37/8 (in Italy) standards. The machine is fitted with an electric plug.
The plug must be connected to the installation of the user according to the maximum electrical input. Provide
the following:
- Equipotential grounding system, -
Automatic protection devices, to be coordinated
with the equipotential system, to ensure automatic cut-off.
The grounding connection shall be done by means of a self-extinguishing yellow-green cable, its minimum section
shall not be below the one of the supply cable. Ensure grounding of all the metallic parts of the machine.
Ensure the protection against lightning and/or electric discharges. The breaking capacity for single-phase
