USE OF THE MACHINE

CHOOSING THE DETERGENT SOLUTION

For a good cleaning of the floor, it is important to choose the proper detergent solution. If
necessary, ask the supplier or a competent person for the proper solution. Keep in mind that a too
strong chemical agent can compromise the long life of each machine. It is necessary to use a low­sudsing detergent solution, or an antifoaming additive, in order not to damage the vacuum motor. If
it is impossible to get these products, use some vinegar to avoid foam, pouring 50cc of it in the
recovery tank before scrubbing.

SCRUBBING

The scrubbing operation is very delicate, as the operator’s experience must be used to decide upon
the brush type, the requirement of a possible double scrubbing operation, the right cleanser choice
and the right machine adjustments: if only one of these factors is inadequate, the scrubbing
operation can give very poor results. If the floor is very dirty or difficult to be cleaned, a double
scrubbing operation is recommended. In this first phase, the squeegee must be lifted and the brushes
must be in working position. Start the brushes and pass the machine over a surface of some tenth sq.
mt. Let the detergent solution on the floor to dissolve the dirt, then pass the machine again. For this
second machine passage, lower the brushes and bring the squeegee in contact with the floor.
Look at the floor after this second passage and decide if the scrubbing operation was enough or if an
additional operation is required. To perform the scrubbing procedure, turn the brush motor ignition
switch to pos. 1, brushes motor start. The brushes will be lowered to the floor pushing on the brush
plate lowering block. Now operate immediately the lever to apply the detergent water, and adjust it
accordingly. Put the run selector (fig.2) in its forward position and press the pedal (fig.3) so that the
machine moves forward and starts scrubbing. The water dosage must be adjusted to get the whole
surface completely wet after the brush passage, but without any excess, that could generate
splashes, stream or flows out of the squeegee. If no double scrubbing is not performed, lower the
squeegee after placing the run switch in forward position. The squeegee is lowered by means of the
pedal. The vacuum motors are operated by means of the switch. Once the scrubbing and drying
procedure are finished, first of all close the water with the lever , then lift the brushes by means of
the pedal and the squeegee by means of the pedal. Finally, turn the motors off.

WATER FILLING AND DISCHARGE, TANK CLEANING

Before every scrubbing operation, open the door and fill the solution tank with the right quantity of
water and cleanser. The tank is made of polyethylene resistant to all acid and basic solution and to
all dissolvents found on the market. At the end of the scrubbing operation, discharge the dirty water
from the tank by means of the hose. Accurately clean the tank at least once per week.

9

SQUEEGEE ADJUSTMENT

The squeegee must be perfectly adjusted to get a perfect floor drying ( fig. 8).
The main characteristic of this type of squeegee is to pick-up the water from the floor and convey to
the vacuum hose, but it must be parallel to the floor. To rightly adjust the squeegee operate as
follow:

• Extract the key from the control dashboard to avoid accidental start of the machine.

• To adjust the squeegee slope operate the knob (fig 3).

• The right pressure is got when the edge of the rear blade touches the floor with a slating of

approx. 60°-45° referring to the floor.

Fig. 3

Note that often drying is negatively affected by a wrong suction operation. If the suction hose
doesn’t work well, drying will continue to be bad, even with all adjustments attempts. In this case:
a- accurately clean the suction hoses, their inlets and filters and the squeegee itself.
b- check the vacuum motors operation.
c- confirm that all inspection openings of the tank are closed.

BRUSHES REPLACEMENT

Before replacing the brushes, extract the key from the control dashboard, this avoiding that any
accidental ignition of some motors could cause damages

• First of all remove the brush carter (fig.4) , doing tractive force towards outside direction on the

carter . In this way you release the carter positioning locks (fig.4)

• Turn the brush into counter clockwise direction so you remove the brush clamping pins from

their house. To fit in the new brush you must put the brush clamping pins into the coupling hole
and turn the brush. After fitting in the brush, you must place the carter into its grooves and
press.
