Safety rules
Before operating the machine make sure that the connection to the power sup-
ply complies with the in force safety rules and the voltage and KW correspond
to the data stated onto the machine label. Never use the electropump if the
connection is not properly made. In case of extension cord, make sure that the
following conditions are respected: lenght of extension up to 50 m for wires
with section up to 4 sqmm; the section becomes 4 and 5 sqmm respectively in
case of 3-phase machines connected at 400 Volt.
The junction between the wire and the extension cord must be properly made
according to the rules.Before turning on the motor, make sure that the gun
trigger is locked on the off position, otherwise the high pressure water jet com-
ing out suddenly may turn the lance into a very harmful thing. If, for switching
the machines off , or for any other reason whatsoever the lance is let down
and the pump is running in By-pass, lock the gun trigger in the off position by
means of the special lock device provided in order to avoid incidental actioning.
Do not intervene on the machine and its accessories when operating.
Do not direct the water jet towards people, animals, frail objects or the ma-
chine itself
Warnings
• The electropump must be continuously and sufficiently fed with clean wa-
ter at volume that must be at least to that of the pump.
• Should the pump run in dry mode, the gaskets and may be seriously dam-
aged.
• Although the electrical equipment of the machines is protected against
water, never use the machines under the rain and never direct the water
against the pressure cleaner itself.
• Avoid operate the machine in places that are non aerated enough and care
not to cover it, thus reducing the necessary aereation inside.
• Do not let the electropump exposed to severe temperatures try protect it
against icing.
• Do not feed the machines with water having a temperature that exceeds 70
°C, otherwise this will inevitably cause seals damages.
• Carefully avoid to let the machines run in BY-Pass condition for longer than
4 hours * in order to prevent the recirculation By-Pass water from heating
