2.4.1 GROUNDINGTHEGENERATORWHENUSEDASA
PORTABLE
This generator has an equipment ground that connects the
generatorframe componentsto the ground terminals on the AC
output receptacles (see NEC 250.34 (A) for explanation).This
allows the generatorto be used as a portablewithout grounding
theframe ofthe generatoras specifiedin NEC250.34.
SpecialRequirements
There may be Federalor State OccupationalSafety and Health
Administration(OSHA)regulations,localcodes,or ordinancesthat
applyto the intendeduse ofthe generator.
Pleaseconsult a qualified electrician, electricalinspector, or the
local agencyhavingjurisdiction:
* In some areas, generators are requiredto be registeredwith
local utilitycompanies.
* If the generatoris used at a construction site, there may be
additionalregulationswhich must be observed.
2.4.2 CONNECT/NGTHEGENERATORTOABU/LD/NG'$
ELECTR/CALSYSTEM
Connectionsfor standby power to a building's electricalsystem
must be made by a qualifiedelectricianand in strict compliance
with all national and local electrical codes and laws. The
connectionmust isolatethe generatorpowerfrom utility poweror
otheralternativepowersources.
NOTE:
Because the generatorequipment ground is bonded to the AC
neutral wires in the generator(see Figure8), either a 3-pole
transferswitch or a 2 pole transferswitch with a switching
neutral kit is requiredto connectthis generatorto a building
load. in this application the generator becomes a separately
derived system(see NEC250.20 (D)), and mustbe grounded
in accordance with the national or local electrical code
requirements.
GroundingtheGeneratorina BuildingStandbyApplication
_ he National Electrical Code requires that the
frame and external electrically conductive parts
of this generator be properly connected to an
approved earth ground.
Local electrical codes may also require proper grounding of the
unit (Figure 10). For that purpose, connecting a No. 10 AWG
(AmericanWire Gauge)strandedcopperwireto the groundinglug
and to an earth=drivencopperor brass groundingrod (electrode)
provides adequateprotection against electricalshock. However,
local codes mayvary widely.Consultwith a localelectrician for
grounding requirementsinthe area.
Proper groundingof the generator will help preventelectrical
shockintheeventof a groundfault condition inthe generatoror in
connectedelectricaldevices.Propergroundingalsohelpsdissipate
static electricity,which often buildsup in ungroundeddevices.
Figure 10- Grounding theGenerator
2.5 DON'TOVEBLOADTHEGENEBATOB
Overloadinga generatorin excess of its ratedwattage capacity
can result in damageto the generatorand to connectedelectrical
devices.Observethefollowing to preventoverloadingthe unit:
* Addupthetotal wattageofall electricaldevicesto beconnected
at one time. This total should NOT be greater than the
generator'swattagecapacity.
* Theratedwattageof lights can betaken from light bulbs. The
ratedwattageof tools, appliancesand motors can usually be
found on a data labelor decalaffixedto the device.
* If the appliance,toot or motor does not give wattage,multiply
voltstimes ampereratingto determinewatts (volts x amps =
watts).
* Someelectric motors, such as induction types, require about
threetimes morewatts of powerfor startingthan for running.
This surge of power lasts only a few seconds when starting
suchmotors. Makesureto allowfor high startingwattagewhen
selectingelectricaldevicesto connectto the generator:
1. Figurethe watts neededto start the largestmotor.
2. Add to that figure the running watts of all other connected
loads.
TheWattageReferenceGuideis providedto assist in determining
how many itemsthegeneratorcanoperateat onetime.
NOTE:
All figures are approximate.See data label on appliancefor
wattage requirements.

2.7.2 ADD/NGGASOLINE
NEVER fill fuel tank indoors. Avoid spilling
gasoline on hot engine. Allow engine to cool
entirely before adding fuel. NEVER fill fuel tank
when engine is running or hot. DO NOT light
a cigarette or smoke when filling the fuel tank.
Gasoline is highly flammable and its vapors are
EXPLOSIVE.
Do not overfill the fuel tank. Always leave room
for fuel expansion. If the fuel tank is overfilled,
fuel can over flow onto a hot engine and cause
fire or an explosion. Wipe up any spilled fuel
immediately.
1. UseregularUNLEADEDgasolinewith thegeneratorengine.Do
not usepremiumgasoline.Do notmix oil with gasoline.
2. Cleanareaaroundfuelfill cap, removecap.
3. Slowly add unleaded regular gasoline to fuel tank. Fill to
bottom of screenfilter. Be carefulnottooverfill (Figure11).
4. Installfuelcap andwipe up any spilledgasoline.
IMPORTANT:Itis importantto preventgum depositsfrom forming
in fuel system parts such as the carburetor,fuel hose or tank
during storage. Alcohol-blendedfuels (called gasohol, ethanol
or methanol)can attract moisture, which leadsto separationand
formationof acids duringstorage.Acidicgascandamagethefuel

2.12 CHARGINGTHEBATTERY(ELECTRICSTART
UNITSONLY)
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.
_tDo not permit smoking, flame, sparks
open
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 shipped withthe generator hasbeen fully charged.
A battery may lose some of its chargewhen not in use for
prolongedperiodsof time. If the battery is unable to crankthe
engine,plugin the12V chargerincludedin the accessory box.
