Otherwise, the material must be disposed of in compliance with the laws in force.
5.4 Electric connections and grounding (models with cable)
On the identification plate (fig. 1) the electric characteristics of the machine are written:
make sure that the frequency and line tension are the same of those of the environment
where you are going to work.
As far as voltage is concerned, the models showing a voltage of 230 V on the plate can be
used for voltages ranging from 220 to 240 V. The same is true for the models showing a
voltage value of 115 V, which can be used for voltages ranging from 110 to 120 V. The
frequency indicated on the plate must always correspond to that of the mains.
*IMPORTANT
Make sure the mains circuit is suitably earthed and that the sockets (and any
adaptors used) ensure the continuity of the earth conductors.
!DANGER
Failure to observe these instructions could cause possibly serious damage to
people and things and invalidates the guarantee.
5.5 Feeding batteries
Two different batteries can be fitted on this machine:
ENGLISH 9

•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,
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
Follow the instructions below to set the type of battery installed on the machine’s
hardware or software.
Battery models: on the back of the control panel, move the bridge (fig. 14) to select the
type of battery installed on the machine (ACID-LEAD/GEL)
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 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) Make sure that the two tanks are empty (empty them, if necessary: see respective
paragraph);
2) Unhook the recovery tank (fig. 2, ref. 2) from the solution tank (fig. 2, ref. 7) acting on
the blocking hook, placed on front of the machine;
3) 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;
4) Insert the batteries in the compartment, orienting them as shown in the drawing printed
on the solution tank in the compartment.
