2.12 CHARGING THE BATTERY (ELECTRIC START
UNITS ONLY)
 Storage batteries give off explosive hydrogen

gas while recharging. An explosive mixture will
remain around the battery for a long time after
it has been charged. The slightest spark can
ignite the hydrogen and cause an explosion.
Such an explosion can shatter the battery and
cause blindness or other serious injury.
Do not permit smoking, open flame, sparks
or any other source of heat around a battery.
Wear protective goggles, rubber apron and
rubber gloves when working around a battery.
Battery electrolyte fluid is an extremely
corrosive sulfuric acid solution that can cause
severe burns. If spill occurs flush area with
clear water immediately.
The battery shipped with the generator has been fully charged.
A battery may lose some of its charge when not in use for
prolonged periods of time. If the battery is unable to crank the
engine, plug in the 12V charger included in the accessory box
(see section "Charging the Battery"). RUNNING THE GENERATOR
DOES NOT CHARGE THE BATTERY.
Use battery charger plug to keep the battery charged and ready for
use. Battery charging should be done in a dry location.
1. Plug charger into "Battery Charger Input" jack, located on the
control panel. Plug wall receptacle end of the battery charger
into a 120 Volt AC wall outlet (Figure 11).
2. Unplug battery charger from wall outlet and control panel jack
when generator is going to be in use.
Do not use the battery charger for more than 48 hours at one
charge.
