6.6 Maintenance Every 300 Hours
6.6.1 Check Battery
Keep flames away from the battery.
Batteries may generate hydrogen gas and may explode.
Therefore, recharging should be done in a
well-ventilated place.
Do not allow sparks, lighted match, or lit cigarette
close to the battery.
Do not check the battery by short-circuiting the positive
and negative terminals with a metallic object.
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℃ to
30℃).
Battery electrolyte is diluted sulfuric acid.
In case of mishandling, it could cause skin burning.
Wear protective gloves and safety glasses when
handling a battery.
If battery electrolyte contacts your clothes or skin, rinse
with large amounts of water immediately.
If the battery electrolyte gets into your eyes, rinse
immediately with plenty of water and see a doctor at
once, because eyesight could be damaged.
Dispose of battery, observing local regulations.
If jumper cables must be used or when cables are re-connected at battery replacement, be
careful not to connect (+) and (-) terminals backwards. Such a miss-connection will cause a
spark or damage each component.
If there seems to be a problem in starting an engine due to a dead battery, carry out
checking by following the procedures below:
(1) Enclosed type battery:
Check the indicator on top surface of the battery.
If the indicator shows that charge is needed, recharge the battery immediately.
(2) Ordinary type battery:
Measure specific gravity of battery electrolyte, and if it shows below 1.24, recharge the
battery immediately.
Refer to 7.2 for method of specific gravity measurement and recharging the battery.
