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 be
run in for a short 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 the pump 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.
4) Do not suck corrosive liquids (paints, acids, solvents, very dense
liquids) as they could 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.
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
reaching the pump through the water
suction hose.

6) Park the machine on flat floor. When
not used, the machine must be stored in
places protected from the atmospheric
agents.
