USE OF THE MACHINE
SAFETY SYSTEM
The machine is equipped with double safety system for emergency stop:
•Mushroom push button . In emergency case press down this button.
•Socket (fig. 3), the same is also used to charge the battery. In emergency case, the socket must
be pull out from the plug using its handle (fig 4).
Before learning how to use the machine, the operator should be familiar with the use of this safety
system, to automatically use it in case of emergency. Never reset the safety system before having
solved the failure, if necessary with the help of a specialized technician.

REVERSE SPEED SAFETY
To avoid operator crushing when machine run in reverse speed, there is a safety (fig.5), that is a
great surface lever. When it touch the operator it disconnect immediately the reverse speed and
insert forward speed. In this way we reduce at the minimum the shock or the operator crushing,
caused by a wrong manoeuvre. Fig. 5
BRAKE
The machine is provided with a parking and an emergency brake as well.(fig.7).
•The emergency brake is controlled by a lever (pos. 3).
•The parking brake is inserted pulling the lever. To disconnect it press down the lever.

INSTALLING THE BATTERY CHARGER
•Install the battery charger in a ventilated and dry place, far from heat sources and corrosive
environments.
•Protect the mains with a delayed switch or with a load fuse higher than the max. power
consumption of the battery charger.
•Observe the polarity of the battery socket (black cables are identified by symbols + and -).
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 low-
sudsing 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.
STARTING AND PREPARING THE MACHINE
If the scrubber is connected to the battery charger (having finished the charge operation), detach the
battery charger plug from the socket (located on the machine) coming from the battery . Then,
connect the plug of the machine to this latter. Close the battery cover again. The machine should be
operated by turning the master key switch. Then, proceed with the water loading described under
the paragraph (par.). Perform the scrubbing once the work place has been reached.
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 on, lower the brushes by screw jack switch, and operate the water adjusting lever. Water
should be metered so as to grant a well-wet surface after the brushes, however without causing any
splashes or overflows from the squeegee due to an excessive quantity of water. If 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.

Fig.6 Fig.7
SQUEEGEE ADJUSTMENT
The squeegee must be perfectly adjusted to get a perfect floor drying ( fig. 8).
The main caracteristic of this type of squeegee is to pick-up the water from the floor and convey to
the vacuum hose, but it must be paralle 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 pression operate the screw nut: unscrewing if you desire to decrease the pression,
or screwing if you desire to increase the pression.
•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. If it is necessary to change the blades slope, it is
necessary to operate the ring nuts.

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 knobs (fig.) by unscrewing them, then extract the brush covering carter
•Rotate each brush until its knob (fig.) can be reached, then extract it and remove the brush fallen
on the ground.
•To insert the new brush, place the hexagon of the female joint (fig.) under the male joint located
on the motor, then lift the brush vertically by rotating it until its automatic insertion has been
reached.
•After placing the brushes, insert the carter and screw the knobs again.
