IMPORTANT
In the case of gel batteries, use a charger specific for gel batteries only.
• Charge the batteries as described in the battery charger manual;
• at the end of charging, disconnect the connectors;
• reconnect the battery wiring connector to the machine connector (machine with external
battery charger).
9. MAINTENANCE INSTRUCTIONS
! DANGER
Never perform any maintenance operations without first unplugging the machine
from the mains (cable version) or disconnecting the batteries.
In cable models, the operator must be able to verify from any position that the
machine remains unplugged from the mains socket while maintenance is being
carried out.
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
manual.
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 high pressure washers. 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 Float switch: cleaning
• Remove the dirty water tank cap and clean the float switch (fig. I, ref. 1). Make sure it
runs freely on the pin.
• clean the detergent tank filter (CT30 ONLY) (fig. N).
9.2.2 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:
• lower the squeegee by means of the squeegee lever (fig. D, ref. 2);
• tip the machine backwards and rest the handle on the floor.
• remove the suction hose sleeve (fig. E, ref. 4) from the squeegee;
• remove the squeegee (fig. E ref. 1) from its mount by completely unscrewing the two
knobs (fig. E ref. 2)
• remove the blade retainers and blades by unscrewing the knobs (fig. E, ref. 5);
• reuse the same blade by reversing the edge in contact with the floor until both edges
are worn out, or replace with a new blade, fitting it onto the screws on the body of the
squeegee;
