5.4.4 Maintenance of Battery
Battery may generate hydrogen gas and may explode. Therefore, recharging should be done at a
well-ventilated place.
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 low battery liquid. Continuing operation
at this lower level will cause deterioration of some parts, reduction of battery life, and also it may
cause explosions. Add distilled water so that the liquid level is between the “UPPER LEVEL” and
“LOWER LEVEL” if the level is too low.
Wear protective gloves and safety glasses when handling a battery.
If battery electrolytes contact your clothes or skin, wash it away with a large amount of water
immediately.
If the battery electrolytes get into your eyes, flush them immediately with plenty of water and see
a doctor at once. Severe damage to eyes and vision may result.
