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 and position it at the desired work height by means of the holes on the legs. Remove the
packing material from the machine and check the machine for possible damages during transport. Before doing this, cut off
the power supply to the machine.

Electric installation
The electric installation of the user must be in compliance with CEI 64.8
standards (Italian law n. 46/90). 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:
- Unipotential grounding system,
- Automatic protection devices, to be
coordinated with the unipotential 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. For installations on
construction sites, connect the grounding system of the construction site to the additional external earthing plug,
placed on one machine leg: use a copper cable with a minimum section of 35 square millimetres provided with cable
terminal and fix the cable terminal to the clamp on the leg with a screw nut (Fig. 2). Ensure good light and visibility of
the machine installation place, according to the work area, and avoid shady areas, dangerous dazzling and
stroboscopic
effects. The Company cannot accept any responsibility in case of wrong electric system or bad
grounding. The motors on the machine are protected by means of a magneto-thermal device. The motors are
provided with special devices to avoid accidental machine starts after electric cut off. After the intervention of the
thermal protections, reset the device with the START push-button.
All the elements and electric apparatus are protected according to the place of use, they have a protection grade of minimum
IP 54 (protection from dust and liquids).
The control panel is placed so that it is visible by the operator while using the machine. It is provided with a STOP push-button
for stopping the machine.
Follow the safety instructions shown in chapter SAFETY PRECAUTIONS.
