STANDARD OPERATION WITH HOT WATER (AT HIGH PRESSURE)
• Check the nozzle support head (30) is not set for the distribution of detergent. Also refer to
THE CLEANER WITH DETERGENT"
• Unscrew the cap (7) and fill the tank with automotive gas oil, making sure the fuel does not spill over.We
recommend using a funnel reserved exclusively for this purpose (maximum tank capacity 18 l / 4,8 US gal).
Replace the cap.
• Turn the high pressure cleaner on again by turning the master switch (1) to
• Select the temperature required using the temperature adjustment knob (41).
• Press the cleaner gun lever (22) and check the nozzle spray is even without dripping.
• If necessary, adjust the pressure using the knob (8). Turn it clockwise to increase the pressure; turn it
anticlockwise to reduce the pressure.
• You can check the pressure level on the pressure gauge (13).
• When the fuel is low, the burner will stop working and the warning light (44) will light up.
• The burner will only start working approximately 3 seconds after the cleaner gun has been opened and
will stop working when the cleaner gun is closed or after it has reached the set temperature.
• If the flame goes out, the burner will stop working and the warning light (49) will light up ("EXTRA"
version only).
• If you want to switch from hot water operation to cold water operation, turn the master switch (1) to
the position.
(MAXIMUM PRESSURE 32 bar 464 psi - ONLY EXTRA)
The EXTRA series high pressure cleaners were designed in compliance with category II of Directive for
pressure equipment (PED). The compliance with this requirement is assured by a special electronic device
that constantly checks:
• that for temperatures above 110 °C/230 °F, the pressure set is below 32 bar/464 psi;
• that for pressures above 32 bar/464 psi, the temperature set is no greater than 110 °C/230 °F.
If the above limits are exceeded, the burner stops and the warning light (48) comes on.
Steam operation will only resume if the pressure is reduced to below 32 bar/464 psi.
• Turn the high pressure cleaner on again by turning the master switch (1) to
to below 32 bar/464 psi by turning the knob (8) anticlockwise.
• Set the temperature between 110°C/230°F and 140°C/284°F using the temperature adjustment knob (41).
• Press the cleaner gun lever (22) and wait for steam to be produced.
• If the burner stops working during use of the cleaner and the warning light (48) lights up, turn the knob (8)
anticlockwise to lower the pressure below 32 bar/464 psi.
• You can check the pressure level on the pressure gauge (13).
• When the fuel is low, the burner will stop working and the warning light (44) will light up.
• The burner will only start working approximately 3 seconds after the cleaner gun has been opened and
will stop working when the cleaner gun is closed or when it reaches the set temperature.
• If the flame goes out, the burner will stop working and the warning light (49) will light up.
The Manufacturer recommends the use of detergents which are at least 90% biodegradable.
Refer to the label on the detergent for instructions on how to use it.
• Turn the master switch (1) to "0" .
• Suction from the high pressure water cleaner tank: take the cap off (11) and, being careful not to
spill any of the liquid (we suggest using a funnel and keeping it for this purpose), fill the tank (maximum
capacity is 3.5 l/0.9 US gal), following the dosage directions given on the detergent pack; put the cap
back on.
• Suction from an external tank: remove the cap (55) and put the fitting (56) of the external detergent
tank suctioning hose (57) in the coupling (54) (also see Fig. 5); put the hose (57) in the external tank
