• WARNING. Do not use the motor 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 motor pump itself or the machine in
which it is integrated.
• WARNING. Explosion risk - Do not spray inflammable liquids.
• Read the “
CHECKING AND CONNECTING UP TO THE HYDRAULIC CIRCUIT (OIL)
” paragraph
carefully.
• Read the “
PRECAUTIONS CONCERNING PUMPED CHEMICAL PRODUCTS
” paragraph carefully.
• Read the “ CHECKING AND CONNECTING UP TO THE WATER CIRCUIT (PUMPED FLUID) ” paragraph
carefully.
• Keep clear of moving parts of the motor 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 motor pump and on the machine in which it is
integrated if this is operating.
• Read the “
intended use
” paragraph carefully.
• Do not modify in any way the installation conditions of the motor pump. In particular, do not modify
the fastening, the hydraulic connections and the guards.
Perform the steps relating to the operation indicated in the manual relating to the machine
in which the motor pump is integrated; unless otherwise indicated, in relation to the motor
pump, the following should be remembered.
a) Before starting the motor pump, fill the suction circuit and pump with liquid. To do this, if the motor
pump has been installed correctly by the Manufacturer of the machine it is integrated in, simply
open the shut-off valve (m) of the fluid at suction. The air will be eliminated through the circuit (b).
b) Starting-up, adjusting rotation speed and stopping the hydraulic motor (u) are normally controlled
by the traction-engine’s hydraulic control unit to which the machine that incorporates the motor
pump is connected.
c) Pressure can be regulated via a device on the machine in which the motor pump is integrated, for
example valve (s).
d) A circuit (r) feeds the stirrer (c) that can be excluded by means of the valve (d).
e) Distribution of the fluid pumped through the nozzles (l) is normally controlled by a unit (f) that
works on the valve (s) and on the shut-off valves (h). The control unit receives information from
various sensors, among which the flow rate measuring device (i).

• Do not operate the motor pump:
-
dry
, i.e. without first having filled the suction circuit and the pump;
- if it is too noisy and/or fluid is dripping from it: in this case have it checked by a SkillED
TEchnician
;
- when exposed directly to sunlight, with ambient temperature above 35 °C (95 °F).
• Before using the motor pump, heat the oil of the hydraulic circuit, leaving it to circulate for about
10-15 min.
