INSTALLATION
1) Check the oil level that must bealways higher than the rod notch.
C
2) Connect the high pressure hose to
the outlet fitting (B), tightening the
B ferrule
completely and the other
end to the automatic gun (C).
3) If the electric current characteristics (Volt/Hz) correspond to those stated
on the label fixed to the machine, you can inser t the plug. The use of
extensions and loose plugs not to standards is prohibited. The
electrical system the machine is connected to must be made in
conformity with the laws in force in the Country of installation. It is
r ecommended to have a differential thermomagnetic switch with
sensitivity equal to 30 m A upstream from the power socket.
CAUTION :
The earth connection is compulsor y .
4) Connect the water supply hose (the
A
inner diameter must be not smaller
than 14 mm) to the pump inlet fitting
(A). Make sure that the suction filter
of the suction fitting is always
clean . The dirty filter causes a bad
water supply and consequently a
very bad pump operation with the
inevitable risk of a rapid wearing
out and breakage of the internal
mechanisms.

ROUTINE MAINTENANCE
The following operations must be done in order to avoid damages to
the mechanical components bearing the heavier work load and to keep your
water pressure cleaner performances efficient.
1) Important ! When the machine is new , the pump/motor set must berun
in for a shor t period. This running in consists of using the machine for
no more than 1 hour and to wait for 1 hour for its cooling;
this operation has to be done 4 or 5 times.
2) Check thepump and gear box oil level periodically , it must always be
higher than the rod notch. Change the pump oil after the first 25 working
hours, then every 300 hours. Use mineral base ISO 6743/4 (DIN
51524) hydraulic oil only , with ISO VG150 viscosity according to ISO
3448 (DIN 51519) standards.
3) Do not leave the machine at very low
temperatures. The frost can damage
the pump and the circuits.
In case of long stay at temperatures
lower than 0 C the operator must
empty the circuits and make
the pump run for some minutes
with antifreeze liquid reaching the
pump through the water suction hose.
Whereas, too high temperature can
cause the motor overheating when the
machine is working.
4) Do not suck corrosive liquids(paints, acids, solvents, very dense
liquids) as they could p permanently damage the pump. After the use of
detergents or other liquids, always suck clean water to avoid deposits
and scales.
5) Check and clean the water filter on the
pressure cleaner at least once a
month.
6) Park the machine on flat floo r .
When not used, the machine must be stored in places
protected from the atmospheric agents.
