• Before using the pump, put on individual protective gear and devices to ensure adequate protection from wrong
manoeuvres with the jet of fluid under pressure.
•
WARNING
. Do not use the pump or the machine in which it is integrated near people if these are not wearing
personal protective equipment.
•
WARNING
. Do not direct high-pressure jets against yourself or other people to clean clothes or footwear.
•
WARNING
. High-pressure jets can be hazardous if incorrectly used. High-pressure jets must not be directed
against people, energized electrical appliances or the pump itself or the machine in which it is integrated.
• Never run the machine in which the pump is integrated in closed premises, if this is driven by an internal
combustion engine.
•
WARNING
. Explosion risk - Do not spray inflammable liquids.
• Read the
“o
peration
with
detergent
”
paragraph carefully.
• Keep clear of moving parts of the pump and of the machine in which it is integrated, even if these are adequately
protected.
• Do not remove the guards of the moving parts.
• Do not touch pipes containing liquids under pressure.
• Do not perform maintenance operations on the pump and on the machine in which it is integrated if this is
operating.
• Read the
“i
ntended
use
”
paragraph carefully.
• Do not modify in any way the installation conditions of the pump. In particular, do not modify the fastening,
the hydraulic connections and the guards.
• Do not open any taps on the pump unless these are connected to an accessory that prevents the accidental escape
of the pumped liquid.
• Do not deactivate or tamper with the controls and the safety devices and the pressure unloader/regulation valve.
• The connection of the machine in which the pump is integrated to the power mains must be made by a Professional
Electrician in accordance with the regulations applicable in the country of use.
During operation:
- always keep an eye on the pump and the machine in which it is integrated and out of the reach of children;
in particular, be very careful when using near nurseries, clinics and old-people’s homes, in case of children,
elderly people or disabled people without supervision;
- do not direct high-pressure jets against materials containing asbestos or other substances harmful for the
health;
- do not cover the pump and the machine in which it is integrated and do not place them where ventilation is
prevented (remember this above all when using the machine in closed environments);
- grip any spray gun tightly because when the lever is operated a reaction force of the high-pressure jet is
produced;
- when not in operation and before doing any jobs, perform the operations described in the
“s
top
”
paragraph;
- operating pressure must never exceed the maximum value set for the pump (see also
“s
peciFications
and
technical
data
”
paragraph);
- use adequate personal protective equipment to safeguard against noise emissions (e.g., ear muffs).
Perform the steps relating to the high-pressure operation indicated in the manual relating to the machine
in which the pump is integrated; unless otherwise indicated, in relation to the pump, the following should
be remembered.
a) To allow pump priming, reset the delivery pressure, and open one of the accessories. In the case of a high-
pressure cleaner, for example, simply keep the spray gun lever pressed.
b) Start the pump.
c) If the possibility exists of adjusting the delivery pressure, set the required pressure. In the case of models
with built-in regulation valve (pumps marked by K preceded by a dash and series AX and BX), pressure
adjustment can be achieved by means of the knob (15): when this is turned clockwise, pressure increases,
when turned anticlockwise, pressure is reduced.
WARNING
• Never touch the pressure unloader/regulation valve so as not to alter its setting: only adjust this valve by
means of the knob (15).
