2.12 CHARGING THEBATTERY (ELECTRIC START
UNITS O NLY)
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.
NOTE:
The battery shippedwith the generator has been fully charged.
A battery may 10se some of its charge when not in use for
pr0i0ngedperiodsof time. if the battery is unable to crank the
engine, plug in the 12V charger includedin the accessorybox.
RUNNING THE GENERATOR DOES NOT CHARGE THE BATTERY.
Use battery chargerplug to keepthe battery chargedand readyfor
use. Batterycharging should be done in a dry location.
1. Plug charger into "Battery ChargerInput"jack, located on the
control panel.Plug wall receptacleend of the battery charger
into a 120 Volt AC walt outlet.
2. Unplugbattery chargerfrom walt outlet and control paneljack
when generatoris going to be in use.
NOTE:

any capableperson or repair shop. Additionally,emissions critical
maintenance must be performed as scheduled in order for the
Emissions Warranty to be valid. Emissions critical maintenance
consists of servicing the air filter and spark plugs in accordance
with the MaintenanceSchedule.
3.2 MAINTENANCE S CHEDULE
Follow the calendar intervals. More frequent service is required
when operatingin adverseconditions noted below.
CheckOilLevel At EachUse
Change Oil $ *Every100 hoursor EverySeason
Check ValveClearance ***Every Season
Service Air Filter ** Every200 hoursor EverySeason
Replace SparkPlug EverySeason
:i: Changeoil after first 30 hours of operation then every season.
* Changeoil and oil filter every month when operating under heavy load or in high
temperatures.
** Clean more often under dirty or dusty operating conditions. Replaceair filter
parts if they cannot be adequately cleaned.
*** Check valve clearance and adjust if necessary after first 50 hours of
operation and every 100 hours thereafter.
