6.1 Maintenance of Battery
Do not connect the cable reversely
If a booster cable has to be used or when cables are connected at battery replacement, be careful not
to connect (+) and (–) terminals backwards. Such a wrong-connection will cause spark and damage
each component.
Handling battery
Keep flames away from battery.
Battery may generate hydrogen gas and may explode.
Therefore, recharging should be done at a well-ventilated
place.
Do not spark near the battery nor light a match, nor bring
lit cigarette and match close to the battery.
Do not check the battery by short-circuiting the positive
and negative terminals with a metallic piece.
Never operate the machine nor charge the batteries with the
battery liquid level being kept lower than the "LOWER" level.
Continuing operation at this lower level will cause deterioration
of such parts as pole plates etc., and also it may cause
explosion as well as reduction of battery life. Add distilled
water so that the liquid level may reach the middle level
between the "UPPER" and "LOWER" level without any delay.
Do not charge the frozen battery. Otherwise it may explode. If
the battery is frozen, warm it up until the battery temperature
becomes 61°F to 86°F (16°C to 30°C).
Battery electrolyte is dilute sulfuric acid.
In case of mishandling, it could cause skin burning.
When you deal with a battery, please be sure to wear
protection implements, such as protection glasses and a
glove.
When such battery electrolyte contacts your clothes or
skin, wash it away with large amount of water
immediately.
If the battery electrolyte gets into your eyes, wash it away
immediately with plenty of water and see a doctor at once,
because it is feared that eyesight might be lost.
Dispose of battery, observing local regulations.
