The machine cleaning can be carried out by non-specialized personnel. However, the person in charge of the cleaning should be familiar with the energy source cut-off main controls and the main features of the machine to avoid any dangerous situation. The machine maintenance should be carried out by highly skilled personnel, with a deep knowledge of the machine and its components. Any cleaning and maintenance operation should be carried out with the machine off. Wait for all the parts to stop and cool down. [. . . ] This means, first and foremost: having a temporary storage authorization. Store in perfectly sealed plastic containers with a capacity at least equal to the volume of the battery electrolyte. On no account should rain water leak into the containers. NOTE Pay the greatest attention when disconnecting the conductors which are live even when the ignition switch is in the "0" position. [. . . ]
