motor ( Photo 16 - C ) wherever foreseen and the
brush motor ( Photo 16 - D ).
When one of these breakers trips automatically, the
disabled function can be reactivated by fully depress-
ing the button of the breaker.
When the thermal breakers trip, especially when the
machine is used during the first few weeks, it might
not be caused by actual machine malfunctions. How-
ever, a specialized technician should check the device
if the relative breaker continues to trip.

PERIODIC MAINTENANCE
For all the operations described herein, refer to the
instructions and detailed warnings in the relative
sections.
7.9.1. DAILY OPERATIONS
Disassemble and check the brush or the pad driver
disk (with the abrasive pad assembled).
Check that there are no foreign bodies that may
impede the movement or efficiency of all cleaning
parts.
Check the squeegee: clean the blades and check their
condition/wear.
If Pb-Acid batteries are used, carefully carry out the
operations described by the battery manufacturer.
Charge the batteries.
7.9.2. WEEKLY OPERATIONS
Check and, if necessary, replace the splash guard.
Carefully check the profile of the squeegee blades
and replace them, if necessary.
Check that the suction hoses and conduits are not
clogged;
Thoroughly clean the solution and recovery tanks.
For other models with the Pb-Acid battery: check the
level of the electrolyte in all elements and, if neces-
sary, top up with distilled water. Refer to the battery
manufacturer's detailed instructions.
Lift the filter compartment cover and check under
the impermeable sponge filter for any signs of liquid;
if there is any, drain it off into the dirty water tank.
7.9.3. OPERATIONS AT EXTENDED INTERVALS
Even though the machine was built with great preci-
sion and conforms to the most severe quality tests,
the electrical and mechanical parts will inevitably be
subjected to wear and aging after extended periods
of use.
For safe and problem-free operation, your machine
should be carefully checked every year by our author-
ized technical service centre (or by a specialist in the
sector familiar with all the pertinent safety regula-
