Warning: these operations must be carried out with the machine off and the key switched
off.
All periodic or extraordinary maintenance operations must be performed by skilled per-
sonnel, or by an authorised service centre.
Note:
The battery life will depend on the level or periodic maintenance (checking the electro-
lyte level and density). If the machine does not run for a long time (ex. 4 to 6 weeks) it
will be necessary to recharge the batteries to make sure that their voltage does not go
under 9,5 Volt. Infact unused batteries get a self-discharge.
