CHANGING THE HIGH PRESSURE NOZZLE.

The high pressure nozzle fitted on the lance must
be changed from time to time, as this component
is subject to normal wear during use. Wear may
generally be detected by a drop in the working
pressure of the cleaner. To replace it, consult your
supplier and/or dealer for instructions.

OPERATIONS FOR USING ANTIFREEZE (fig.
17).
1)

Turn off the water supply (tap), disconnect the

hose and run the cleaner until it is completely
empty.

Stop the water cleaner with the ON/OFF switch

in the “O” position (fig.10A).

Prepare a container with the solution of an-

tifreeze.

Immerse the tube in the container with the

anti-freeze solution.

Start the water cleaner with the ON/OFF switch

in the “I” position.

Start the cleaner and let it run until antifreeze

comes out through the lance.

Suck up antifreeze with the detergent intake

system too.

Switch off the cleaner and disconnect the electric

power by switching off the omnipolar switch,via
the omnipolar switch or by unplugging the plug
from the socket.

Anti-freeze may cause environmental pol-
lution. Always follow the instructions given

CHECKING PUMP OIL LEVEL AND OIL CHAN-
GE.

From time to time check the oil level in the high
pressure pump by means of the sight glass (fig.
18A) or the dipstick (fig. 18B).
If the oil has a milky appearance, call the technical
service centre immediately.
Change the oil after the first 50 hours' work and
subsequently every 500 hours or once a year.
Proceed as follows:

Unscrew the drain cap situated under the pump

(fig. 18C).

Unscrew the cap with the dipstick (fig. 18).

Let all the oil drain off into a container and

deliver it to an authorized oil collection and di-
sposal centre.

Replace the drain screw and pour fresh oil

in through the filling cap on top (fig. 19A) until
it reaches the level indicated on the sight glass
(fig. 19B).

For water cleaners without oil drain bung,
contact our technical service centre for re-
placement.
Use only SAE 15 W40 oil.
CLEANING THE WATER FILTER

Clean the water intake filter regularly and free it
from any impurities (fig. 20).

TABLE OF EXTRAORDINARY MAINTENANCE
TO BE PERFORMED BY THE TECHNICAL
SERVICE CENTRE.

IMPORTANT:

These intervals refer to normal working condi-

tions. For heavy duty use decrease the interval

for each job.

For maintenance and/or repairs, use only
original spare parts which offer the grea-

test characteristics of quality and reliability.

Failure to use original spare parts absol-

ves the manufacturer from all liability and

transfers it to the person carrying out the

operation.

PERIODS OF INACTIVITY

If the machine is to remain inactive for a long
period, disconnect the supply sources, drain the
tank(s) of all the operating fluids and protect any
parts that could be damaged by the accumulation
of dust.
Grease the parts that could be damaged by drying
out, such as the supply hoses.
