constructed by qualified technicians capable of
working in accordance with the requirements
of the regulations in force (earth connection,
fuses, differential security breaker, etc).
In case of failure to comply with one of the
regulations stated above, the manufacturer
declines all responsibility for the staff and
provides no warranty.
IMPORTANT: Regarding three-phase motors,
pay attention to the connection of the electric
cable to the plug (see electric diagram).

When the machine is running again, check that
the jet is even; otherwise, clean the nozzle to
remove any dirt. Wait a few seconds for the op-
erating pressure to be reached, then operate
the gun for two or three short bursts.
