Exterior
Make sure that the 12-volt battery terminals are not corroded
and that there are no loose connections, cracks, or loose
clamps.
■
Before recharging
When recharging, the 12-volt battery produces hydrogen gas which is flam-
mable and explosive. Therefore, observe the following precautions before
recharging:
●
If recharging with the 12-volt battery installed on the vehicle, be sure to
disconnect the ground cable.
●
Make sure the power switch on the charger is off when connecting and
disconnecting the charger cables to the 12-volt battery.
