at least once per week) to ensure the battery is filled to the max. marking with acid.
► In the event of the following, do not start the device or switch it off immediately and
have the battery checked by an authorised workshop:
Uneven acid levels or high water consumption in individual cells
Impermissible warming of the battery to above 55 °C (131 °F).
