5.5.4 Maintenance of Battery
Battery may generate hydrogen gas and can explode. Therefore, recharging should be done in a
well-ventilated place.

Do not check the battery by short-circuiting the positive and negative terminals with a piece of
metal.

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 LEVEL" and "LOWER LEVEL"
without any delay.

Wear protective gloves and safety glasses when handling the 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.
