WARNING
When checking or handling the battery, stop the engine and
turn the starting switch key to the OFF position before
starting.
The battery generates hydrogen gas, so there is danger of
explosion. Do not bring lighted cigarettes near the battery, or
do anything that will cause sparks.
Battery electrolyte is dilute sulphuric acid, and it will attack
your clothes and skin. If it gets on your clothes or on your
skin, wash it immediately off with large amounts of water. If
it gets in your eyes, wash it out with fresh water, and consult
a doctor.
When handling battery, always wear protective goggles.
When removing the battery, first disconnect the cable from
the ground (normally, from the negative 0 terminal). When
installing, install the positive @terminal first. If a tool touches
the cable connecting the positive terminal and the chassis,
there is danger that it will cause sparks.
If the terminals are loose, there is danger that the defective
contact may generate sparks that will cause an explosion.
When installing the terminals, install them tightly.
When removing or installing, check which is the positive @
terminal and negative @ terminal.
When removing,
disconnect the
cable from the
ground terminal
first.
