Electrical connections and earth (cable models)
The electrical characteristics of the machine are given on the rating plate. Make sure the frequency and voltage
correspond to those of the mains supply where the machine will be operated. As far as voltage is concerned,
models where the rating plate specifies a voltage of 230 V can be used with voltages of between 220 V and 240
V. Similarly, models rated at 115 V can be used at between 110 V and 120 V. The frequency on the plate must
always correspond to the mains voltage.
Make sure the mains circuit is suitably earthed and that the sockets (and any adaptors used) ensure the
Failure to observe these instructions could cause possibly serious damage to people and things and
Power supply batteries (battery models)
Two different types of battery may 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 requires no maintenance.
The technical characteristics must correspond to those indicated in the paragraph on the technical specification of
the machine. 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.
They must be kept charged, dry and clean and the connections must be tight.
Batteries: preparation
During installation of the batteries or any type of battery maintenance, the operator must be provided
with the necessary personal protection devices (gloves, goggles overalls, etc) to limit the risk of accident.
Keep away from naked flames, avoid short circuiting the battery poles, avoid sparks and do not smoke.
The batteries are normally supplied filled with acid and ready for use.
If the batteries are dry, before mounting them on the machine, proceed as follows:
►
remove the caps and fill all elements with specific sulphuric acid solution until the plates are entirely
covered (this requires at least a couple of passes for each element);
►
leave for 4-5 hours to allow the air bubbles to come to the surface and the plates to absorb the elec-
trolyte;
►
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
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
Meticulously follow the instructions given below as short circuiting the batteries could cause them to
►
Make sure the dirty water tank is empty and empty if necessary (see relevant paragraph).
►
Remove the dirty water tank (fig. B, ref. 1) off the detergent tank by pulling it upwards, making sure you
have previously removed the suction hose and dirty water tank drain hose from their housings.
►
Place the batteries in the battery compartment.
Mount the batteries on the machine using lifting means suitable for their weight.
►
Connect the battery wiring and bridge terminals to the battery poles.
