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. 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.
5.5.1. Batteries: preparation
! DANGER
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 electrolyte;
• 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.
5.5.2. 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.
• Make sure the dirty water tank is empty and empty if necessary (see relevant
paragraph).
• Lift 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.
