WARNING: Failure to follow these safety precautions may lead to a serious accident. SAFETY CHARGING BATTERY ! If the battery is handled incorrectly when it is being charged, there is danger that the battery may explode, so follow the instructions in HANDLING BATTERY and in the instruction manual for the charger, and always observe the following precautions. ! Carry out the charging in a well-ventilated place, and remove the battery caps. This disperses the hydrogen gas and prevents explosion. ! Set the voltage on the charger to match the voltage on the battery to be charged.
If the voltage setting is wrong, it will cause the charger to overheat and catch fire, and this may lead to an explosion. Connect the positive ( [ ) charging clip of the charger to the positive ( [ ) terminal of the battery, then connect the negative ( - ) charging clip to the negative ( - ) D terminal of the battery. Be sure to tighten both terminals securely. ! If the battery charge is less than 1/10 of the rated charge, and high speed charging is carried out, set to a value below the rated capacity of the battery. ! If there is an excessive flow of charging current, it may cause leakage or evaporation of the electrolyte, whichmay catch fire and explode. 1-23
