aged.

not corroded or damaged.
Make sure that the breather hose is not
clogged or damaged.Checking the electrolyte level
Make sure that the electrolyte level is be-
tween the maximum and minimum level
marks.
If the electrolyte level is low, add distilled wa-
ter to raise it to the specified level. NOTICE:

the battery, otherwise battery life could be
shortened.

tery. If you charge the battery yourself, be
sure to read and follow the instructions pro-
vided with the battery tester and charger you

battery hastily. Battery life could be short-
ened.
