(3) Charging attentions
When charge the equipped storage battery:
●
Disconnect the distribution line of battery before charging.
●
Charge at ventilated place.
●
Disconnect the negative wire first when disconnecting the distribution line of battery.
(If there is any tool between positive pole and machine, electrical spark may be produced,
leading to extreme risk.)
When connecting the distribution line of storage battery, connect the positive wire first and
negative wire finally.
●
Ensure sufficient ventilation during charging.
Keep away from ignition source or forbid any actions producing electrical spark because
charging produces inflammable gas.
●
Re-charge the storage battery after intervals if storage battery is extremely hot, i.e. electrolyte
temperature is above 45
℃
.
●
Stop charging immediately as storage battery is full.
There are following disadvantages if the charging continues when storage battery is full.
1) Over-heat of storage battery
2) Reduction of electrolyte
3) Abnormality of storage battery
●
Connect the positive wire prior to negative wire.
●
Incorrect wiring may damage the engine.
