Directive 97/23/EC 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 (25).

• Press the cleaner gun lever (24) and wait for steam to be produced.

• If the burner stops working during use of the cleaner and the warning light (32) 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 (10).

• When the fuel is low, the burner will stop working and the warning light (28) 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.

by-pass operating mode, and if it remains in this condition it will stop automatically after approximately

13 seconds (Total Stop).
