3. The batteries charge level indica-
tor (1) is digital. The battery charge
level starts at 90, which indicates
the 90% of the total charge and
decreases by 10’s. When the charge
level reaches 20%, the display
starts blinking, and you are near the
end of work time.
ATTENTION:
After a few seconds of the four
lines, the brush motor stops au-
tomatically. With the remaining
charge it is possible to nish the
drying operation before proceeding
to the recharge station.
Hour meter
The machine is equipped with an
hour meter located in the same
display as the battery charge level
indicator (1). Keeping the but-
ton (8) pressed for more than 3
seconds, will display the working
hours. Continue holding and after
a few seconds the working minutes
are shown.
Squeegee assembly
1. Hold the squeegee support (1)
slightly off of the oor.
2. Insert the two stud bolts (3)
placed on the upper part of the
squeegee (2) inside the slots on the
support.
3. Lock the squeegee by rotating
the lever (4) clockwise.
4. Insert the squeegee hose (5) into
its coupling on the squeegee as-
sembly.
Adjustment of the squeegee
In order to have a perfect drying
result by the squeegee, the rear
rubber must have the lower bend-
ing uniformly adjusted across its
full length. For the adjustment, it
is necessary to put the unit in an
operating mode, the suction motor
has to be switched on and the brush
have to function together with the
solution.
If the lower part of the rubber is
bent too much
Take off the pressure rotating the
wing nut (6) counterclockwise.
If the lower part of the rubber is not
bent enough
Increase the pressure rotating the
wing nut (6) clockwise.
If the bending is not uniform across
the whole rubber
Adjust the squeegee inclination by
rotating counterclockwise the wing
nut (7) to increase the bending in
the central part, or clockwise to
increase the bending on the ex-
tremities.
Height adjustment
Once the pressure and inclination
of the squeegee have been adjusted,
it is necessary to maintain this
optimum condition by making the
wheels slightly touch the oor. Ro-
tate the at knob (8) counterclock-
wise to lower the wheels or clock-
wise to raise them. Both wheels
must be adjusted in the same.
https://harrissupplyind.com-ToOrderPartsCall608-268-8080

14
ATTENTION:
Every type of oor requires a
specic adjustment. For example,
concrete oors (where the friction
tends to be high) need little pres-
sure, while smooth oors (ceram-
ics) need higher pressure.
If the cleaning operations are
always made on the same type of
oor, the adjustment can change
only as the rubbers wear.
Splash guard assembly
The two splashguards have to be
assembled onto the brush base
group. Insert the metal strips inside
the suitable slots on the rubber.
Place the round hole at the at
end of the strip onto the screw
(1) placed in the front part of the
brush base group. Secure the strips
through the nut locking it.
Lock the coupling levers (2) in the
rear part of the brush base group to
the rings placed at the ends of the
metal strips still free. Repeat for the
other splashguard. Ensure that the
gap between the two rubbers in the
front part of the brush base group is
to reduced to a minimum.
With brush assembled, the splash-
guard must slightly touch the oor.
Brush assembly
The machines that have the electri-
cal brush base lifting:
1. Switch on the machine by turn-
ing the key (9) clockwise.
2. Press the push button (7) of up/
down brush base to lift the brush.
3. Turn off the unit by turning the
key (9) counterclockwise
ATTENTION:
To carry out brush assembly opera-
tions with the electric supply on,
may cause damages to hands.
With the brush base group in lifted
position, insert the brush into their
plate seat underneath the brush
base turning them until the three
metal buttons are properly seated
in their slots; rotate the brush to
push the button towards the cou-
pling spring until they are locked in
place.
The gure shows the rotating direc-
tion for brush coupling.
We suggest to daily alternate the
brush position for a longer brush
life. Whenever a brush becomes
deformed, we suggest installing
them in the same position. This will
avoid motor overload or vibrations
from the different inclination of the
bristles.
ATTENTION:
Use only brush supplied with the
machine or the ones indicated in
the paragraph “RECOMMENDED
BRUSH”. The use of other brush
can compromise security.
Floor Cleaning
Connecting the batteries to the
machine Once the battery charging
has been completed:
1. Disconnect the connector (3)
from the battery charger (1).
https://harrissupplyind.com-ToOrderPartsCall608-268-8080

15
To do this, it is necessary to reach
the battery compartment as indi-
cated under paragraph “ACCESS
TO THE BATTERY COMPART-
MENT”.
2. Connect the machine connector
(2) to the batteries.
3. Close the battery compartment.
Recovery tank
Check that the cover of the suction
lter (1) is correctly secured, after
rotating the levers (2) and that the
suction motor hose (3) is correctly
connected to it.
Verify also that the squeegee hose
couplings (4) are correctly inserted
into the seats, that the exhaust hose
plug (5) placed in the front part of
the machine is closed and that the
inspection cap (6) is closed as well.
DETERGENT SOLUTION TANK
The capacity of the detergent solu-
tion tank is indicated in the techni-
cal data.
Open the screw plug placed in the
rear left part of the machine and
ll the detergent solution tank with
clean water at a maximum temper-
ature of 50°C. Add the liquid deter-
gent in the percentage and condi-
tions foreseen by the manufacturer.
To avoid excessive foam presence,
which could cause problems to the
suction motor, use the minimum
percentage of detergent. Screw
down the plug to close the tank.
ATTENTION:
Use always low foam detergent. To
avoid foam pres¬ence, before start-
ing working operation, introduce
into the recovery tank a minimum
quantity of anti-foam product.
Never use pure acid.
STARTING OF THE MACHINE
1.Turn the key (9) clockwise.
2.Check the battery type and the
charge level on the display (1).
3.Press the brushes motor switch
(6).

and the squeegee starts to dry.
10.During the rst metres/feet,
check that the squeegee adjustment
guarantees a perfect drying action
and that the detergent solution ow
is appropriate. It has to be sufcient
to wet the oor uniformly avoid-
ing the leakage of detergent from
the splash guards. Always consider
that the correct quantity of solution
detergent depends on type of oor,
dirtiness and machine speed.

The traction of the machine is
given through an electronically
controlled motor.
To move the machine, turn the key
(9) clockwise, then rotate the drive
control levers (12) placed on the
handle bar, when pressed forward
you activate the forward drive,
when pulled backwards the reverse
movement is activated. The control
acts in a progressive way, the
further the levers are pushed the
faster the unit goes, therefore it is
possible to graduate the speed
depending on the job requirement
by rotating the lever to whatever is
necessary. When going in reverse
the speed is reduced.
Speed adjustment
Two values of the maximum drive
speed in forward movement can be
chosen. Press the switch forward
for fast speed and rearward for
slow speed.
Set the desired speed through the
speed selection switch (2).
ATTENTION:
When moving the machine
backwards, make sure that the
squeegee is lifted.
Security device reverse movement
A large-sized push button (13),
placed on the rear of the machine
is for the automatic drive reversal.
If the operator unintentionally
remains blocked between the
machine and an obstacle, this push
button forces the control to reverse
the machine when it touches the
operator.
Working brake
To stop the machine during normal
working situation, it is sufcient to
release the drive control levers
(12), as the machine is equipped

immediately. The emergency brake
also functions as a parking brake.
To start to work again, release the
lever by unlocking the parking
button on the lever itself and
pushing on the drive control levers
(12).
Adjustment of the brush pressure
Through the knob (1) it is possible
to adjust the brush pressure on the
cleaning surface.
By turning the knob clockwise the
pressure increases, rotating it
counterclockwise, decreases the
pressure.
This device allows a more efcient
cleaning action on very difcult
and dirty surfaces.
The control of the adjustment of
the brush pressure is possible
through a sliding indication. It’s
position shows the value indicated
on the label placed in
correspondence of the slots where
it slides.
On the 24-Volt machines the
indicator is placed in the rear part
of the frame inside the battery
compartment.
ATTENTION:
In order not to overload the brush
motor, reduce the brush pressure
going from smooth oors to rough
ones (ex. concrete).
