3.1 General description
The machine is a sweeping scrubber, which can be used in civil and industrial
environments for sweeping, washing and drying flat, horizontal, smooth or moderately
rough floors, with even surfaces and free from obstacles. It is available either in the
version with battery or with cable to meet with any requirements of autonomy and weight.
The scrubber distributes on the floor an adequately dosed solution of water and detergent,
and brushes it to remove dirt. Choosing with care the right cleaning detergent and brushes
(or abrasive discs or rollers) in the wide range of accessories available, the machine can
adapt itself to all kinds of combinations of floors and dirt.
With the liquid suction system incorporated in the machine, the floor can also be dried
after washing. Drying is performed by means of the underpressure in the recovery tank
generated by the suction motor. The floor cleaner, connected to the tank, collects the dirty
water.

repair.
Otherwise, the material must be disposed of in compliance with the laws in force.
!DANGER
Failure to observe these instructions could cause possibly serious damage to
people and things and invalidates the guarantee.
5.4 Feeding batteries
Two different batteries can be fitted on this machine:
Tubular leak-proof batteries: these batteries require the periodical check of the
electrolyte level. When it is necessary, top up with distilled water alone until the plates
are covered; do not overfill (max. 5 mm. above the plates).
Gel batteries: this kind of batteries requires no maintenance.
The technical specifications must correspond to those indicated in the paragraph
concerning the machine technical data: actually, the use of heavier storage batteries can
cause serious problems to the machine controllability and overheat the drive motor,

ENGLISH
10
whereas storage batteries with a lower capacity require recharges more frequently.
They must be kept charged, dry and clean, with their connections tight.
i INFORMATION

hazards of accidents, keep away from possible free flames, do not short-circuit the
battery poles, cause sparks or smoke.
The batteries are normally supplied filled with acid and ready-for-use.
If batteries without acid are to be used, before mounting them on the machine, it is
necessary to make them active as follows:
After taking off the battery plugs, fill up all elements with a solution of specific
sulphuric acid, until the cells are thoroughly covered (fill each element at least twice);
Let them rest for about 4-5 hours, to give time to air bubbles to come up to the
surface and the plates to absorb the electrolyte;
Check that the electrolyte level is still above the plates, otherwise top up with the
solution of sulphuric acid;
Reclose the plugs;
Install the storage batteries on the machine (following the procedure described below).
It is now necessary to perform a first recharging before having the machine start; to
do so stick to the instructions written in the respective paragraph.
5.4.2 Batteries: installation and connection
!DANGER
Check that the key switch on the control panel is at the position “0” (off).
Mind you connect only the clips marked with the symbol “+” to the positive poles.
Do not check the battery charge by creating sparkles.
Stick scrupulously to the instructions described below, as any short circuits of the
batteries may cause them to explode.
1) Stop the machine and press the emergency button (fig. A, ref. 1);
2) Make sure that the two tanks are empty (empty them, if necessary: see respective
paragraph);
3) Unhook the recovery tank (fig. B, ref. 2) from the solution tank (fig. B, ref. 1) acting on
the blocking hook (fig. B, ref. 10), placed on right side of the machine;
4) Lift the recovery tank, by making it turn backwards around about 90°: in this way you
have access to the battery compartment (embedded in the solution tank) from the
upper side;
