screws, chips, cords or similar items, has become jam-
med.
Check that the brushes are flat as they work on the
surface (check for any irregular wear on the brushes
or on the abrasive disks). If necessary, adjust the slant
of the action on the floor.
Use only the accessories recommended by the manu-
facturer: other products may reduce operating safety.
8.5 MACHINE BODY
Use a sponge or a soft cloth to clean the exterior of the
machine and, if necessary, a soft brush to eliminate
tough dirt. The machine's shockproof surface is rough
to make it harder to see scratches caused during use.
However, this does not make it easier to remove tou-
gh stains on the surface. Steam machines can be used
but it's prohibited to use hoses with running water or
a high-pressure cleaner.
8.6 BATTERIES
8.6.1 PB-ACID
Carry out maintenance operations in accordance with
the manufacturer's instructions and with all the other in-
structions provided in this manual.
Exposing the element plates (not completely immersed
in the acid solution) will lead to rapid oxidation and irre-
parably reduce the element's operating capacities.
An overflowing acid solution may corrode the machine.
Use battery chargers recommended by the manufac-
turer and, in any case, those that are suitable for the
type of battery to be charged.
Always charge batteries in well-ventilated rooms: the-
re is an explosion risk!
The use of gel or maintenance-free batteries is highly
recommended.
8.6.2 GEL
Carry out maintenance operations in accordance with
the manufacturer's instructions and with all the other
instructions provided in this manual.
Use only those battery chargers recommended by the
manufacturer.
8.7 FUSES AND THERMAL BREAKERS
The machine is equipped with electric protection
devices on the main operating components to avoid
costly malfunctions.
Thermal cutouts are installed to protect the drive mo-
tor wherever foreseen and the brush motor.
When one of these breakers trips automatically, the
disabled function can be reactivated by fully depres-
sing the breaker that tripped.
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. Howe-
ver, a specialised technician should check the device if
the relative breaker continues to trip.
8.8 PERIODIC MAINTENANCE
For all the operations described herein, refer to the
instructions and detailed warnings in the relative sec-
tions.
8.9 RECOMMENDED SPARE PARTS
You'll always be able to use your machine as efficien-
tly as possible by maintaining a stock of the most
common consumable materials and by scheduling
routine and extraordinary maintenance. Contact your
dealer for a list of these spare parts.
9. OPERATING CHECKS

The batteries are dead.
Charge the batteries.
9.2 THE BRUSHES DON'T ROTATE
The brush motor switch is not selected.
Press the button to activate the brushes.

the reset breaker (the first from the top).
The transmission belt is broken.
Replace it.
The motor relay or the brush motor is broken.
Replace it.
9.3 NOT ENOUGH OR TOO MUCH DETERGENT
