16. TROUBLESHOOTING 16.3.2 PRECAUTIONS FOR CHARGING BATTERY CHARGING BATTERY WHEN MOUNTED ON MACHINE When charging the battery, if the battery is not handled correctly, there is a hazard that the battery may explode. Always follow the instructions of “16.3 IF BATTERY DISCHARGED” and the instruction manual accompanying the charger, and do as follows. Set the voltage of the charger to match the voltage of the battery to be charged. If the voltage is not selected correctly, the charger may overheat and cause an explosion.
Connect the positive + charger clip of the charger to the positive + terminal of the battery, then connect the negative - charger clip of the charger to the negative - terminal of the battery. Be sure to fix the clips securely. Set the charging current to 1/10 of the value of the rated battery capacity; when carrying out rapid charging, set it to less than the rated battery capacity. If the charger current is too high, the electrolyte will leak or dry up, and this may cause the battery to catch fire and explode. If the battery electrolyte is frozen, do not charge the battery or start the engine with a different power source.
There is a hazard that this will ignite the battery electrolyte and cause the battery to explode. Do not use or charge the battery if the battery electrolyte level is below the LOWER LEVEL line. This may cause an explosion. Always check the battery electrolyte level periodically and add distilled water to bring the electrolyte level to the UPPER LEVEL line. 2-109
