WARNING – RISK OF EXPLOSIVE GASES
Working in the vicinity of a lead-acid battery is dangerous. Batteries
generate explosive gases during normal battery operation. For this
reason, it is of the utmost importance that you follow the instructions
each time you use the charger.
PERSONAL PRECAUTIONS:
■ Consider having another person close by when working with a
lead-acid battery.
■ Have plenty of fresh water and soap in case battery acid encounters
eyes, skin or clothing.
