6.8.2 Battery charging
Improper handling can result in explosion
when the battery is charged. Follow the in-
struction,
see
“
Battery
”
on page 6-30
and the
instruction of charger, and proceed the proce-
dure below:
●
Regulate the charger to the voltage appli-
cable to the battery. Incorrect voltage can
over heat the charger and cause explo-
sion.
●
Connect the charger's positive clip (+) to
the battery's positive terminal (+). Connect
the charger's negative clip (-) to the bat-
tery's negative terminal (-). The wire clips
must be
fi
xed.
●
Regulate the charging current to 1/10 of
the rated capacity of battery. In case of
quick charging, regulate the charging cur-
rent to a level below the rated capacity of
battery. Larger charging current may cause
leakage or evaporation of electrolyte,
hence
fi
re and explosion.
●
If the battery electrolyte freezes, do not
charge the battery, or use an alternate
power supply to start the engine. Charging
a frozen battery may cause electrolyte to
catch on
fi
re and the battery to explode.
