squeegee touching the floor. When the washing and
drying operation has finished. The last operation is
to turn off the motors. When the washing operation
has finished, the recovery tank has to be emptied
of the dirty water through the outlet tube. It is a good
rule to thoroughly clean the recovery tank once a
week.
The squeegee has to be regulated to perfection to
dry the floor perfectly. The correct pressure is reached
when the edge of the back blade touches the floor
with an inclination of approximately 60/45°. If the
pressure is too high the back blade touches the floor
with the side surface and not with the edge, if it is
too low the edge does not work well and leaks water,
leaving damp puddles on the floor.
The perfect drying of the floor will indicate the right
regulation of the squeegee and perhaps it will be
necessary to try several times before reaching this
point. It is important however to remember that often
the drying is influenced by the bad functioning of
the suction plant. If this should happen, it is necessary
to:
· Thoroughly clean the suction tubes, the inlets
and the squeegee itself.
· Check the functioning of the suction motor.
· Check that the inspection opening of the tank is
tightly closed.
· Clean perfectly the suction motor filter.
Rotate the brush in one of the two directions until
it falls off. To insert the new brush, place it under
the male joint on the machine, put the brushes
support down and turn on the brushes motor.
The electric machine may be turned on only if the
voltage indicated on the tag corresponds with the
available voltage and that the electrical outlet is
grounded (earthed).
Do not damage the feed cable; do not crush or pull
on it. Do not run over the feed cable with the machine.
The cable could wind up in moving parts causing a
short circuit.
- The electric machine has parts,
which are connected to the current; contact with
these could cause grave injuries or even death.
· Before executing any type of operation on the
machine always disconnect it from the electrical
source.
· Never touch electric cables that are defective or
worn.
· Before gaining access to the electrical system it is
always necessary to disconnect the machine from
the electrical source.
· In the case of defective, damaged, or cracked
electric cables, replace immediately with authentic
replacement parts.
· The network of connections must be protected
from water spray.
· Use of extension cords for the machine’s network
connections is not allowed in any case.
· The electrical system to which the machine is
connected must be equipped with a cut-out box.
· It is absolutely forbidden to use the machine in
proximity to swimming pools or stretches of water.
In case of emergency:
· Immediately disconnect the machine from the
electrical source.
· Immediately apply proper first-aid.
If an accident should occur the machine must not
be put into operation until a technician authorised
by the manufacturer has examined it.
– Every maintenance or repair
intervention that is not described in the following
pages must be carried out by specialised personnel,
authorised by the manufacturer.
Clean the recovery tank.
Check the cleanliness of the suction hose and of
the squeegee.
Check the suction filter
-
Check the condition of the brushes.
Check the condition of the rubber blades of the
squeegee.
Check the suction motor.
-
Check the conditions of the washing solution inlet
valve.
-
Check the conditions of the carbon plates for every
motor.
As it is a known fact that there is a direct relationship
between the specific weight of the electrolyte and
the state of the battery charge, the measurement
of the specific weight of the electrolyte is taken as
an effective correct control of the state of the battery
charge. When the battery is charged and in normal
conditions, with the electrolyte at the right level, the
density of the electrolyte will be about 1.260 kg/lt
(30° Bè) referred to 30°. If instead the density is
15
