When the engine has warmed up for some minutes,
switch it off pulling the indicated head (40).
Set the gear lever (33) in position

Start again
the engine.
Make sure that the machine works correctly:
• Open and
close two
or three
times the
delivery
air cock
(37), to
m a k e
s u r e
that the
pneuma-
tic remote control works properly. The engine goes
to a minimum re-
volution and the
centrifuge joint cuts
the transmission to
the pumping group.
Start the machine
opening the delivery
air cock (37): the pump starts to push the slurry previou-
sly poured in the hopper.
With the by-pass lever (20) always in vertical position
(recycle of material into the hopper), check that the pump
is engaged.
If this does not happen switch off the machine
Make sure that the by-pass lever (20) is in vertical
position (recycle of material into the hopper).
Caution: the machine must always work with
material or water in the hopper.
Failing to do so the wear and tear of the piston will
increase dramatically.
In order to start the engine turn the key (39) in
position 1.
As soon as the engine has started close the air delivery
