Battery Float Charger
Use battery float charger jack to keep the starting battery
charged and ready for use. Battery charging should be done
in a dry location, such as inside a garage.

which is located next to the start switch. Plug battery
charger into a 120 Volt AC wall receptacle.
2. Unplug charger from unit and wall outlet when
generator is being started and while it is in operation.
3. Keep this charger plugged in when generator is not in
use to prolong battery life. The charger has a built in
float equalizer and will not overcharge the battery, even
when plugged in for an extended period of time.
