OPERATION AND USE
6.7.7 Cleaning of heavily dirty, hard or dingy flooring
CAUTION
Do not products that are: “Static dissipative detergents” as can
damage the brushes and plastic parts of the appliance.
To clean very dirty or caked flooring, proceed as follows:
1)
Use an all-purpose concentrated non-foaming and non-acid detergent (pH max. 9).
2) Fit the supplied grey brushes for medium dirt or the black brushes (option) for heavy dirt.
3) Raise the recovery tank by turning the knob 6 and set it to “ 1 ”. In this setting the recovery
system will not work and the liquid poured onto the floor will require a more emulsified
solution, and therefore, it will allow the detergent to be more effective (soaking).
4) Press the lever to dispense a large amount of detergent consisting of product/water,
preferably warm at a temperature of 35/40°C.
5)
Move the appliance forward on the entire wet surface, in all directions or following
precise tracks.
6) Stop the appliance and turn the knob to “0” to lower the tank and re-activate the dirty
water recovery system. Resume moving the appliance forward on the entire wet surface.
CAUTION
After cleaning heavily dirty flooring, clean the appliance and brushes
very accurately.
Do not use the dirty appliance to spread the wax.
