end of work time.

ATTENTION:
After a few seconds of the four
lines, the brush motor stops au­tomatically. With the remaining

charge it is possible to nish the

drying operation before proceeding
to the recharge station.

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 as­sembly.

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.

Hour meter
The machine is equipped with an
hour meter located in the same
display as the battery charge level
indicator (1). Keeping the but­ton (8) pressed for more than 3
seconds, will display the working
hours. Continue holding and after
a few seconds the working minutes
are shown.

Adjustment of the squeegee
In order to have a perfect drying
result by the squeegee, the rear
rubber must have the lower bend­ing 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 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 ex­tremities.
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. Ro­tate the at knob (8) counterclock-

wise to lower the wheels or clock­wise to raise them. Both wheels
must be adjusted in the same.

in their slots; rotate the brush to

https://harrissupplyind.com - To Order Parts Call 608-268-8080

push the button towards the cou­pling spring until they are locked in
place.
The gure shows the rotating direc­tion for brush coupling.

ATTENTION:

Every type of oor requires a
specic adjustment. For example,
concrete oors (where the friction

tends to be high) need little pres­sure, while smooth oors (ceram­ics) 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 electri­cal brush base lifting:

1. Switch on the machine by turn­ing 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 opera­tions 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

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).

14

To do this, it is necessary to reach

https://harrissupplyind.com - To Order Parts Call 608-268-8080

the battery compartment as indi­cated under paragraph “ACCESS
TO THE BATTERY COMPART­MENT”.

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 solu­tion tank is indicated in the techni­cal 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 temper­ature of 50°C. Add the liquid deter­gent in the percentage and condi­tions 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 start­ing working operation, introduce
into the recovery tank a minimum
quantity of anti-foam product.
Never use pure acid.

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.

RECOMMENDED BRUSH

Brush must be chosen depending on type of oor and dirt to be removed. The employed material and the bristle

diameter are the elements that distinguish different types of brush.

MATERIAL CHARACTERISTICS
PPL (Polypropylene) Good wear resistance. Maintains a characteristic with hot water up to 140°F (60°C). It is

not hygroscopic.
NYLON Excellent wear resistance, even with hot water over 60°C. It is hygroscopic. It looses its physical

characteristics over time.

TYNEX Nylon bristles with grains of abrasive material. Use with caution in order not to mark the oor or ruin

the polishing.

BRISTLES THICKNESS Thicker bristles are more rigid and must be used on smooth oor or oor with small
joints. On irregular oors 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 is equipped with anchor points that permit the locking of the abrasive pad. The pad is rec-

ommended to clean smooth oors.
