ADVICE ON USING DETERGENTS
USE OF THE DOUBLE LAN-
CE. (fig.11) (if available).
The double lance allows the
operator to select a low or high
pressure jet. The pressure is
selected with the gun in pos.
1. High pressure: pos. 2. Low
pressure.
REGULATING PRESSURE
AND USING STEAM.
This chapter concerns only
those models provided with
the “pressure regulating” de-
vice. The pressure regulator,
fig. 12, allows the operator to
adjust the working pressure.
When knob C is turned in
an anti-clockwise direction
(B) (minimum), the working
pressure is reduced.
USING STEAM.
Use the steam nozzle (supplied as an accessory).
Turn the thermostat knob “B” (fig. 8) to steam position to obtain
an increase in the temperature of the water at delivery.
At work temperatures higher than 95°C (203°F), the work
pressure must be < 32 bar (460 PSI).
Danger
During use with boiling water, "Steam Phase", keep away
from the openings for fumes discharge (risk of burning).
When you have finished using the "Steam Phase", turn the
thermostat knob "B" to position "0" (fig. 8) and let the ma-
chine cool down for about 3minutes with the gunturned on.
Warning
This cleaner has been designed for use with the detergents
supplied or recommended by the manufacturer.
The use of other detergents or chemicals may influence the
safety of the cleaner.
1) For environmental compatibility, we recommend a reaso-
nable use of detergents, according to the instructions on the
pack.
2) From the range of recommended products, choose the
one most suited to the washing job to be done and dilute it
with water according to the instructions on the pack or in the
catalogue of the detergents most suited for the type of hot or
cold water cleaner.
3) Ask your dealer for the detergents catalogue.
OPERATING PHASES FOR CORRECT CLEANING WITH
DETERGENTS.
1) Prepare the solution of detergent at the concentration
most suitable for the type of dirt and the surface that is to be
washed.
2) Start the cleaner, turn on the detergent tap, and spray the dirty
surface with the diluted product, working from bottom to top.
Let it react for a few minutes.
3) Rinse the whole surface well from top to bottom with hot or
cold water at high pressure.
4) After use with detergent, rinse the high pressure water circuit
by operating the pump for one minute with the detergent tap
completely closed.
Danger
For maintenance of the boiler, high pressure pump, the electrical
parts and all parts with a safety function, you must apply to our
Technical service centre.
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.

the instructions given on the pack. (Dispose of carefully.)
CHECKING PUMP OIL LE-
VEL AND OIL CHANGE
From time to time check the
oil level in the high pressure
pump by means of the sight
glass (fig. 14A) or the dipstick
(fig. 14B).
If the oil has a milky appearan-
ce, 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.
14C).
2) Unscrew the cap with the
dipstick (fig. 14).
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

PERIODS OF INACTIVITY
SCRAPPING
CHANGING THE NOZZLE
The high pressure nozzle fitted on the lance must be chan-
ged 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.
TABLE OF ROUTINE MAINTENANCE TO BE PER-
FORMED BY THE USER
DESCALING
Descaling must be carried out from time to time because the
