Before towing the machine (versions without mixer only and in
countries where this is admitted in observance of current stan-
dards) position the tiller correctly so that the attachment, with the
machine horizontal and the end section of the tiller horizontal, is
at the height of the towing hook, tighten the various elements of
the tiller fully down, hook up the safety cable, connect the lighting
cable, check the tyre pressure (...bar) and operation of the lighting
devices, ensure that there are no plastering machine elements or
other materials present (sacks of material, hoses, tools etc.), and
ensure correct conditions of the machine in general.

9. INSTALLATION
Position the plastering machine in a suitably ventilated envi-
ronment where it does not constitute an obstruction either during
use or cleaning at the end of the work shift and where a minimum
quantity of pipelines is required
Place the machine according to the application
- in a clear area if ready-to-use bags are fed into the machine or
if the optional mixer is installed.
- below the auxiliary mixer outlet in the case of mixes being mixed
on site
The machine must always be placed on a flat surface: a slight
downward inclination of the cam pump will aid outlet of the ma-
terial (fig 5).
Route machine pipelines as required by the product application,
avoid excessive bends or kinks on the hoses. If pipelines are routed
upwards, secure the lines to scaffolding or other support points.
Apply or connect the accessories and components as required
for the specific application.

10. CONNECTIONS
10.1 ELECTRICAL CONNECTION (see fig.6)
and electrical connection (socket, fuses, cable) correspond
to specifications in table 1.
The electrical power line must be fitted with protection against
current overload (e.g. by means of fuses or a thermal magnetic
cut-out) and against indirect contact (e.g. with a differential circuit
breaker (max. 30 mA). The electric cable wire size must take into
account the operating currents and length of the line to avoid
excessive voltage drops.
Avoid use of extension leads wound on drums. The power cable
must be suitable for frequent movements and with an abrasion
resistant sheath (e.g. type H07RN-F).
Before connecting the plastering machine to the electrical mains,
ensure that all safety devices are fitted and are in perfect con-
dition, and check in particular that the hopper grid is secured in
place, that the extension in good condition and that the plugs and
sockets are not wet.
Connect the plastering machine plug to the mains (fig. 6, ref. 1).
The 2P+T single phase 3P+T 3-phase and socket for remote
control 3P+T YELLOW must be mobile type IP67.
If the optional mixer is used, connect it to the plastering machine
socket (fig. 6, ref. 2).
10.2 AIR CONNECTION
FOR SPRAYING ONLY
Connect the air delivery directly to the jet as in the case of control
of the machine by means of the incorporated pneumatic control
(see para.4.2).
The machine can be controlled by means of the electric pendant
control supplied.
To restart the compressor if it does not resume operation au-
tomatically, press the red pushbutton on the power pressure
switch located inside the cabin (on both single and three-phase
versions, fig.6.1)
could damage the electric motor.
Ensure that there are no air leaks that cause repeated start-ups
at intervals of less than 15s; this will damage the electric com-
pressor motor.
