Weber Clean Track NANOscrub Manuel D'instructions page 46

Remove and clean the brush or the abrasive pad
disk.
• To avoid damaging the floor and the machine,
carefully check if foreign matter, such as metallic
parts, screws, chips, cords or similar items, has be-
come jammed.
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
manufacturer: other products may reduce operat-
ing safety.
8.6 MACHINE BODY
Use a sponge or a soft cloth to clean the exterior of
the machine and, if necessary, a soft brush to elimi-
nate 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 tough stains on the surface. It is prohib-
ited to use steam machines, hoses with run-
ning water and high-pressure cleaners.
8.7 BATTERIES
PB-Acid batteries
Carry out maintenance operations in accordance
with the manufacturer's instructions and with all the
other instructions provided in this manual.
Exposing the element plates (not completely im-
mersed in the acid solution) will lead to rapid oxida-
tion and irreparably reduce the element's operating
capacities.
An overflowing acid solution may corrode the ma-
chine.
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:
there is an explosion risk!
The use of gel or maintenance-free batteries is
highly recommended.
GEL batteries
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.
8.8 THERMAL BREAKERS
The machine is equipped with electric protection
devices on the main operating components to avoid
costly malfunctions.
Thermal breakers are installed to protect the suction
motor ( Photo 16 - C ) wherever foreseen and the
8 - MAINTENANCE INFORMATIONS
brush motor ( Photo 16 - D ).
When one of these breakers trips automatically, the
disabled function can be reactivated by fully de-
pressing 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 de-
vice if the relative breaker continues to trip.
8.9 PERIODIC MAINTENANCE
For all the operations described herein, refer to the
instructions and detailed warnings in the relative
sections.
8.9.1 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.
8.9.2 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.
8.9.3 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 au-
thorized technical service centre (or by a specialist
in the sector familiar with all the pertinent safety
regulations contained in this manual).
This type of work may have to be carried out more
frequently if the machine operates in particular/dif-
ficult situations and/or if required maintenance was
