WARNING!
Make sure the mains system is suitably earthed and that sockets ensure the continuity of the earth
conductors.
DANGER
Failure to observe these instructions could cause serious injury to persons or damage to property, as well
as invalidating the warranty.
Power supply batteries (battery powered versions)
DANGER
Installation and connection / removal of the batteries must be carried out by an IPC-approved technician
(hereinafter referred to as qualified personnel).
Two different types of battery can be installed on these machines:
► tubular leak-proof batteries: the electrolyte level must be checked regularly. When necessary, top up
with distilled water until the plates are covered. Do not over-fill (5 mm max. above the plates).
► gel batteries: this type of battery is maintenance-free.Technical characteristics must correspond to
those indicated in the machine technical specifications section. The use of heavier batteries could
seriously jeopardise manoeuvrability and lead to the brush motor overheating. Batteries with a lower
capacity and weight will require charging more frequently. Batteries must be kept charged, dry, clean
and with tight terminals.
Batteries: preparation
DANGER
During installation of the batteries or any type of battery maintenance, the skilled technician must be
provided with the necessary personal protection devices (gloves, goggles, overalls, etc) to limit the risk
of accidents. Keep away from naked flames, do not short circuit the battery poles, do not generate sparks
and do not smoke.
Batteries are normally supplied filled with acid and ready for use.
If the batteries in use are dry charged, they must be activated before being installed in the machine. Proceed as
follows:
► remove the caps and fill all elements with specific sulphuric acid solution (see the table below) until the
plates are entirely covered (this requires at least a couple of passes for each element);
Ambient temperature

% Sulphuric acid % Distilled water
> + 35°C > + 95°F 25% 75%
from 0°C to + 35°C from +32°F to + 95°F 30% 70%
from 0°C to - 20°C from +32°F to - 4°F 40% 60%
< - 20°C < + 4°F 45% 55%
►
leave for 4-5 hours to allow the air bubbles to come to the surface and the plates to absorb the electro-
lyte;
►
make sure the level of electrolyte is still above the plates and if necessary top up with sulphuric acid
solution;
►
close the caps;
► mount the batteries on the machine (following the procedure described below).
Before starting up the machine for the first time, charge the batteries as follows.
Batteries: installation and connection
DANGER
Check that all switches on the control panel are in the "0" (off) position.
Make sure you connect the terminals marked with a "+" to the positive poles of the battery. Do not check
the battery charge by sparking.
Meticulously follow the instructions given below as short circuiting the batteries could cause them to
explode.
