WARNING
Check that the electric plant is provided with a suitable ground line and that the
plugs (and any reducers being used) guarantee the continuity of the ground lead
wires.
!
DANGER
The non-observance of the prescribed rules can cause serious damages to persons
and things and the invalidity of the guarantee.

Feeding batteries (models with battery)
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 brush motor,
whereas storage batteries with a lower capacity require recharges more frequently.
They must be kept charged, dry and clean, with their connections tight.
5.5.1 Batteries: preparation
!
DANGER
On installing or performing any kind of maintenance on the batteries wear the
necessary accessories (e.g. protective gloves, goggles, overalls, etc.) to limit the
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.
5.5.2 Batteries: installation and connection
!
DANGER
Check that all switches on the control panel are 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) Make sure that the two tanks are empty (empty them, if necessary: see respective
paragraph);
