Machine does not start
Acqua
Water pressure too low: the gauge shows pressure below 2 bar (green lamp on?), the
display shows the text H

Machine does not start
Air
- The air pressure, with jet valve completely open, does not fall below the minimum pres-
sure value on the machine pressure switch (table 1)

- Check that water is delive-
red from the supply hose
is clean
- Check that the water pump
is switched on
- If the pump collects from a
tank, check that it has been
primed and there are
no leaks from couplings
- Initial start-up not performed
correctly (see para.11)
low (see para.11)
- No water delivered to
mixing chamber
(water inlet obstructed,
water solenoid valve mal-
function)
- Check that the air hose is
not bent or obstructedo
- Check that the jet nozzle is
perfectly clean
- Check points listed
alongside
- Check points listed
alongside
- Check that water does not
continue to enter the mixing
chamber when the
machine is stationary
- Empty hopper (see para.11)
- Ensure that the electric
cable section is adequate
(see para.10.1)
- Check the current line to
the site panel and site panel
connector
- Check motors, electric
cables and connectors
- Check the air hose and
couplings in particular and
replace if necessary

- Check compressor relief
valve
- Check points listed alongsi-
water hose (at least 10-12
l/min if working with lime-
cement based plaster, at le-
ast 15-20 l/min with gypsum
based plasters) and replace
hose if necessary or collect
water from an auxiliary tank
