water and consult a doctor without delay.

Batteries which do not require maintenance should not be opened.
q
It is advisable to add distilled water just before starting work, in order to prevent if from freezing.

Check that the terminals and connection cables are not rusted; if necessary, clean and protect them
with antioxidant grease.
