batteries).
or
Pb 24 (check card set for lead
batteries).
3. The battery charge level indicator is
digital and remains fixed on the
display. The battery charge level
starts from 100, which indicates 100%
of the total charge and decreases in
10’s to 10. When the charge level
reaches 20%, the display starts
blinking.
ATTENTION:
After a few seconds when the four
lines start blinking, all the functions
stop automatically. With the remaining
charge it is possible to finish the
drying operation before proceeding to

4. The writing GE24 appears flashing.
5. When the writing stops flashing, the
setting is modified.
To change the setting from gel
batteries to lead batteries, repeat the
procedure pressing button (3) instead
of button (6).
HOUR METER
The machine is equipped with an hour
meter located on the same display (1)
as the battery charge level indicator.
Hold the button (13), the first data
indicates the working hours and after
a few seconds the working minutes
are shown.
SQUEEGEE ASSEMBLY
1. Keep the squeegee support (1)
slightly lifted from the floor.
2. Insert the threaded parts of the two
bolts (4) sliding them inside the two
slots on the support placed on the
upper part of the squeegee (2).
3. Put the washers (3) into position,
there are two for each bolt, so that
they are assembled one under and
the other over each of the two slots
present on the support.
4. Secure the squeegee by rotating
the two levers (4) clockwise.
5. Insert the squeegee hose (5) into
its coupling, follow the picture for
positioning.
SQUEEGEE ADJUSTMENT
In order to achieve good drying
results, the rear rubber of the
squeegee must be bent equally in
length. To adjust, it is necessary to
put the machine in operation and
therefore the vacuum motor has to be
switched on and the brushes have to
function together with the detergent
solution.
The lower part of the rubber is overly
bent
Take off the pressure by rotating the
wing nut (6) counterclockwise.
The lower part of the rubber is not
bent enough
Increase the pressure rotating the
wing nut (6) clockwise. Check that the
wheels that adjust the height are not
resting on the floor, in this case adjust
them as indicated in paragraph
"Height adjustment".
The bend is not equal
Adjust the squeegee inclination
rotating the wing nut counterclockwise
(7) to increase the bend in the central
part, or clockwise to increase the
bend on the outer part.
Height adjustment
Once the pressure and inclination of
the squeegee have been adjusted, it
is necessary to fix this optimum
condition ensuring the wheels only
slightly touch the floor. Rotate
counterclockwise the bolts (8) to lower
the wheels or clockwise to raise them.
Both wheels must be adjusted to the
same height.
ATTENTION:
Every type of floor requires a
specific adjustment. For example,
concrete floors (where the friction
results will be high) need little
pressure, while smooth floors
(ceramics) need higher pressure.
If the cleaning operations are made
always on the same type of floor, the
adjustment can change only in
function of the rubber wear.
SPLASH GUARD ASSEMBLY
The two splash guards have to be
assembled onto the brushes base
group as indicated in the following
figures. Insert the metal strips inside
the slots present on the rubber. Place
the round hole at the extremity of the
strip onto the screw (1) place in the
front part of the brushes base group.
Secure the strips through the nut
blocking it.
Secure the coupling lever (2) in the
rear part of the brushes base group to
the ring placed at the extremity of the
metal strip still free. Repeat as above
for both splash guard rubbers.
The splash guard must slightly touch
the floor when the brushes are
assembled.
To remove the splash guard follow the
above instructions in reverse.

10
ASSEMBLING THE BRUSHES
To assemble the brushes it is
necessary that the brushes base is in
the lifted position. If it is not lifted,
proceed as follows:
Without the operator seated, turn the
key switch clockwise, the display
comes on and after 3 seconds all
working groups switch off
automatically and are lifted from the
floor.
Switch off the machine turning the key
counterclockwise.
ATTENTION:
Carrying out brush operations with
the electric supply on may cause
injury.
With the base of the brushes in the
lifted position, insert the brushes into
their plate seat underneath the
brushes base turning them until the
three metal buttons are properly
seated in their slots; rotate the
brushes to push the button towards
the coupling spring until they are
locked.
The figure shows the rotating direction
for brushes coupling.
For a longer life of the brushes we
suggest to daily alternate their
position. Whenever brushes do
become deformed we suggest to
reassemble them in the same position,
in order to avoid that the different
inclination of the bristles causes
excessive motor overload or
troublesome vibrations.
ATTENTION:
Use only brushes supplied with the
machine or ones indicated in the
paragraph “RECOMMENDED
BRUSHES”. The use of other brushes
can affect the cleaning result.
FLOOR CLEANING
RECOVERY TANK

RECOMMENDED BRUSHES
Brushes must be chosen depending on floor type and dirt to be removed.
The material and bristle diameter are the elements that distinguish different types of brushes.
MATERIAL CHARACTERISTICS
PPL (Polypropylene) Good wear resistance. Maintains characteristics with hot water up to 50°C. It is not hygroscopic.
NYLON Excellent wear resistance, even with hot water. It is hygroscopic.
TYNEX Nylon bristles with grains of abrasive material. Use with caution in order not to mark the floor or
ruin the polishing.
BRISTLES
THICKNESS
Thicker bristles are more rigid and must be used on smooth floor or floor with small joints. On
irregular floors with deep joints or relieves, it is recommended to use softer bristles which
penetrate more easily and deeper. Please be aware that when brush bristles are worn out and
therefore too small, they become rigid and unable to penetrate and clean deeper. This may also
happen with thicker bristles creating brush vibration.
PAD HOLDER
It has anchor points which permit the blocking of the abrasive pad during work. The pad is recommended to clean smooth floors.
