3. Accidents prevention
3.1. The instructions furnished in this manual don’t replace in any way the norms related to the safety, to the
installation and the use, to the technical data or the norms in force in the nation of installation or use or the
norms dictated of the common sense.
3.2. Technicians or maintenance technicians are obliged to notify any possible defects or deteriorations that
are able, in any way, to compromise the original safety of the plant.
3.3. The serial high pressure cleaner is not equipped for working in environments characterized by particular
conditions of inflammability or explosiveness; flameproof equipment is supplied only and exclusively on
specific request. It is forbidden to install the high pressure cleaner in environments where inflammable
materials are present or with particles it suspended in the air: acids, inks, varnishes, resins, solvents, plastic
subjects, etc.; follow the norms imposed by the fire department.
3.4. The high pressure cleaner and its plant as the place and the environment, are forcedly exposed to the
water and the damp that injure the natural conditions of isolation of the plant. Don’t use therefore unsafe
electric cables, thorns or plugs, and sockets; check the integrity and the insulation of the electric cable,
t
ogether with the equipment of the operators. Don’t absolutely touch the thorn or the plugs with wet hands or
feet. To avoid accidental switching on, turn the interrupter on OFF before inserting or disconnecting the
power supply. Don’t pull the high pressure cleaner using the electrical cable or extract its thorn from the
socket.
3.5. Use with extreme care the chemical detergents not to deteriorate the environment (degradability
90%), parts or components of the machine, according to the updating of the legislative decree. Besides,
always check the degradability and the aggressiveness of the used detergents. Never use acids, inks,
solvents, liquid oily, varnishes, resins, etc…
3.6
. The “cold” starting of the high pressure cleaner can cause some serious damages to the pump and the
circuits; the standstill prolonged at temperatures under 0°C could cause breakups and damages to the
pump and the pipes; therefore the emptying of the machine is advisable.
3.7. Always protect the high pressure cleaner from the atmospheric agents, from the cold and from the frost.
3.8. Never direct the jet of water towards people (not even to clean their clothes or their shoes) or animals,
nor the machine itself or any objects under electrical tension.
3.9. Lance and gun, although equipped with proper hilts, have a modest counterblow (about 22N) to the
departure of the jet; hold them with strength with both hands. Never touch the jet of water during the
operation of the high pressure cleaner.
3.10. If some defects, damages or deteriorations on the machine are found, disconnect it immediately, and
call an assistance authorized center or the supplier.
3.11
. Don’t leave never, without overseeing, the high pressure cleaner working in presence of children.
3.12. ATTENTION: If used in the correct way and it is in a good state, the high pressure cleaner sends forth
a sonorous level of pressure (noisiness) of 101 dB.
3.13. The maximum level of vibrations of the lance during the operation is 22m/sec

3.14.
The high pressure cleaner has security devices for a safety use:
-Pressure switch
-Magnetothermic switch for motor protection
-By-pass valve
-Water Float (LASER MAX)
-Electric controls 24V
-Timed total stop system DSS
3.15. The high pressure cleaner is provided with a timed total stop system. If the pistol remains closed for
more than 10 sec., the motor will stop. The motor will start again by opening the pistol. In addition the
machine will stop after 10 false starts (due to micro-leaks) or after 60 minutes without use. In this case the
red light will blink. To restart the machine, turn OFF the switch Q1 and then, turn it ON again.
3.16. ATTENTION: The by-pass security valve allows to regulate the flow and the pressure of the water. In
addition it protects the pump from overpressure. The valve is set to the maximum allowed pressure and the
nut on the knob is sealed with paint. Replacements, reparations and new regulations must be made by
specific and authorized personnel.
3.17 ATTENTION: The magnetothermic switch protects the motor from overloads. In case of overload the
magnetothermic switch stops the motor. To restart the motor, turn OFF the main switch and then turn it ON
again. Replacements and reparations must be made by specific and authorized personnel with the machine
unplugged from the electricity network.
