Never perform any maintenance operations without first disconnecting the batteries
Maintenance on the electrical circuit and all other operations not explicitly
described in this manual must be performed by specialised personnel only, in
compliance with current safety legislation and as described in the maintenance
9.1. Maintenance - General rules
Performing regular maintenance according to the Manufacturer's instructions improves
performance and extends the working life of the machine.
When cleaning the machine, respect the following:
• avoid the use of water cleaners. Water could penetrate the electrical compartment or
motors leading to damage or the risk of short circuit;
• do not use steam to avoid the heat warping plastic parts;
• do not use hydrocarbons or solvents as they could damage the cowling and rubber
parts.
9.2. Routine maintenance
9.2.1 Suction motor air filter and float: cleaning
• Raise the cover (fig. G, ref. 2) of the collection tank;
• make sure the collection tank (fig. B, ref. 2) is empty;
• clean the collection tank float (fig. G ref. 3), making sure not to aim the water jet directly
against the float;
• remove the suction motor air filter from the float support (fig. G ref. 1) inside the
collection tank at the top;
• clean the filter with running water or the detergent used on the machine;
• dry the filter thoroughly before replacing it in the support. Make sure the filter is
correctly located in its housing;
• Close the collection tank cover.
9.2.2 Detergent solution filter: cleaning
• Before cleaning the filter, close the tap (fig. H ref. 2) upstream of the filter.
• Unscrew the filter cap (fig. H ref. 1);
• Remove the filter from its housing by pulling downwards;
• Clean the filter with running water or the detergent used on the machine;
• Replace the filter in its housing
• Screw up the filter cap
9.2.3 Squeegee blades: replacing
The squeegee blades collect the film of water and detergent from the floor and prepare
the way for perfect drying. With time, the constant rubbing makes the edge of the blade in
contact with the floor rounded and cracked, reducing the drying efficiency and requiring it
to be replaced.
Turning or replacing the blades:
• remove the squeegee (fig. B ref. 6) from its support (fig. E ref. 3) by completely
unscrewing the two knobs (fig. E ref. 2)
• remove the sleeve of the suction hose (fig. E, ref. 1) from the squeegee;
• release the clip or unscrew the bolt (fig. I ref. 3 or 6);
