PRECAUTIONS WHEN CHARGING BATTERY 3
When charging the battery, if the battery is not handled cor-
rectly, there is danger that the battery may explode. Always
follow the instructions in “IF BATTERY IS DISCHARGED (3-
142)“ and the instruction manual accompanying the charger,
and do as follows.
q
Set the voltage of the charger to match the voltage of the
battery to be charged. If the correct voltage is not selected,
the charger may overheat and cause an explosion.
q
Connect the positive (+) charger clip of the charger to the
positive (+) terminal of the battery, then connect the nega-
tive (-) charger clip of the charger to the negative (-) termi-
nal of the battery. Be sure to attach the clips securely.
q
Set the charging current to 1/10 of the value of the rated battery capacity; when carrying out rapid charging,
set it to less than the rated battery capacity.
If the charger current is too high, the electrolyte will leak or dry up, and this may cause the battery to catch fire
and explode.
q
If the battery electrolyte is frozen, do not charge the battery or start the engine with a different power source.
There is a danger that this will ignite the battery electrolyte and cause the battery to explode.
STARTING ENGINE WITH BOOSTER CABLE 3
When starting the engine with a booster cable, do as follows:
REMOVAL, INSTALLATION OF BATTERY CABLE
1. Open the battery cover (1).
2. Before removing the battery, remove the ground cable
(normally connected to the negative (-) terminal). If any tool
touches between the positive terminal and the chassis,
there is danger of sparks being generated. Loosen the nut
of the terminal and remove the wires from the battery.
3. When installing, connect the ground cable last.
Insert the terminal cable on the battery, then tighten the
nut.
Tightening torque: 9.8 to 19.6 N·m (1.0 to 2.0 kgf·m)
4. Close battery cover (1).
