Cleaning Machines KF66B, Manual

or similar tool to do this.
Water hotter than 50°, a high-pressure cleaner or
excessively powerful sprays may damage the tanks
and the machine.
Leave the plugs of the tanks open (only while the
machine is not being used) so that they can dry and
thus prevent the formation of foul odours.
8.2 SUCTION HOSE
Detach the suction hose from the squeegee.
Now you can wash the hose and remove any
obstructions.
Firmly insert the hose on the squeegee body.
8.3 SQUEEGEE
Do not handle the squeegee with bare hands: wear
gloves and any safety clothing needed to carry out the
operation.
Detach the squeegee from the machine and clean it
under running water using a sponge or a brush.
Check the efficiency and the wear on the strips in
contact with the floor. They are designed to scrape the
film of detergent and water on the floor and to isolate
that portion of the surface to enhance the vacuum of
the suction motor: this ensures that the machine will
dry very efficiently. Working constantly in this manner
tends to round or to deteriorate the sharp edge of the
strip, thus reducing drying efficiently. This is why the
squeegee strips must be replaced.
To replace the worn straps, follow the instructions in
the relative section. Turn the straps around to wear
down the other sharp corners or to install new ones.
8.4 ACCESSORIES
Remove and clean the brushes or the scraper disks.
To avoid damaging the floor and the machine,
carefully check if foreign matter, such as metallic parts,
screws, chips, cords or similar items, has become
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 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 tough
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
instructions provided in this manual.
Exposing the element plates (not completely immersed
in the acid solution) will lead to rapid oxidation and
irreparably reduce the element’s operating capacities.
An overflowing acid solution may corrode the machine.
Use battery chargers recommended by the manufacturer
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.
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 motor
wherever foreseen and the brush motor.
When one of these breakers trips automatically, the
disabled function can be reactivated by fully depressing
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. However,
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 sections.
8.8.1 DAILY OPERATIONS
Disassemble and check the brushes or the scraper
disks (with the abrasive disks mounted).
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.
8.8.2 WEEKLY OPERATIONS
Check and, if necessary, replace or adjust the height
of 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;
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.
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 necessary,
top up with distilled water. Refer to the battery
