components with a safety function must be carried out by an
authorised technical service centre only.
The manufacturer is not liable in case of tampering, changes, in-
correct repairs or maintenance carried out on the machine by a
third person not provided with the manufacturer's authorization.
All documents pertaining to the repair and planned service
interventions, as well as any certificates concerning the de-

from the water supply (by closing the tap) and the mains electri-
city supply (by turning off the omnipolar switch and unplugging
it from the mains socket) (see chapters on connecting to the
mains electricity and water supplies).
After completing the maintenance, before reconnecting the high
pressure washer to the mains electricity and water supplies,
make sure the panels are replaced correctly and fixed with
the screws.
Failure to do so may cause
a risk of electric shock.
PRECAUTIONS AGAINST
FROST
The cleaner must not be
exposed to frost.
If the cleaner is left in premises
where it is exposed to frost,
when work is over or for sto-
rage, antifreeze must be used
to prevent serious damage to
the hydraulic circuit.
OPERATIONS FOR USING ANTIFREEZE (fig. 14)

CHECKING PUMP OIL LEVEL AND OIL CHANGE
From time to time check the oil level in the high pressure pump
by means of the sight glass (fig. 15A) or the dipstick (fig. 15B).
If the oil has a milky appearance, call the technical service
centre immediately.
Change the oil after the first
50 hours' work and subse-
quently every 500 hours or
once a year.
Proceed as follows:
1) Unscrew the drain cap
situated under the pump (fig.
15C).
2) Unscrew the cap with the
dipstick (fig. 15).
3) Let all the oil drain off into
a container and deliver it to an
authorized oil collection and
disposal centre.
4) Replace the drain screw
and pour fresh oil in through
the filling cap on top (fig.
16A) until it reaches the level
indicated on the sight glass
(fig. 16B).
For water cleaners without
oil drain bung, contact our
technical service centre for
replacement.
Use only SAE 15 W40 oil.
