Checking battery (for electric start
models)

WARNING

EWM00330

Battery electrolytic fluid is dangerous; it
contains sulfuric acid and therefore is
poisonous and highly caustic.
Always follow these preventive mea-
sures:

●

Avoid bodily contact with electrolytic

fluid as it can cause severe burns or
permanent eye injury.

●

Wear protective eye gear when han-
dling or working near batteries.

Antidote (EXTERNAL):

●

SKIN - Flush with water.

●

EYES - Flush with water for 15 minutes
and get immediate medical attention.

Antidote (INTERNAL):

●

Drink large quantities of water or milk
followed by milk of magnesia, beaten
egg, or vegetable oil. Get immediate
medical attention.

Batteries also generate explosive hydro-
gen gas; therefore, you should always
follow these preventive measures:

●

Charge batteries in a well-ventilated ar-
ea.

●

Keep batteries away from fire, sparks,
or open flames (for example: welding
equipment, lighted cigarettes, and so
on.)

●

DO NOT SMOKE when charging or han-
dling batteries.

KEEP BATTERIES AND ELECTROLYTIC

FLUID OUT OF REACH OF CHILDREN.

CAUTION:

ECM00360

●

A poorly maintained battery will quickly
deteriorate.

●

Ordinary tap water contains minerals
harmful to a battery, and should not be

used for topping up.

Check the electrolyte level at least once
a month. Fill to the manufacturer’s rec-
ommended level when necessary. Top
up only with distilled water (or pure de-
ionized water suitable to use in batter-
ies).
