6.1 Maintenance of 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 16°C to 30°C.

Battery electrolyte is dilute sulfuric acid.
In case of mishandling, it could cause skin burning.

Wear protective gloves and safety glasses when handling a
battery.
 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 .


Never reverse the cable connections. － When a booster-cable is unavoidably used or when a set of
cables is connected after a battery change, be sure to correctly connect the electric terminals (+) and (–).
Reversely-connected cables will cause sparks or damage to components .
