SAFETYRULES
This generator set was designed and manufacturedfor spe-
chic applications. Do not attempt to modifythe unit or use it
for any application it was not designed for. Ifyou have any
questions about your generator's application, ask your
Oeater!Oisfributoror consutt the factory.
The manufacturer could not possiblyanticipate every cir-
cumstance that might involve a hazard. For that reason
warningsinthe Manualand warningson tags or decals affixed
tothe unit are not all-inclusive. Ifyou intendto handle, oper-
ateorservicethe unitbyaprocedureor methodnotspecifically
recommendedby the manufacturer,first make sure that such
a procedure or methodwill not render this equipment unsafe
or posea threatto you and others.
Read this manual carefullyand become familiar with your
generator set. Know its applications, its limitations and any
hazards involved.
. The generator producesavery powerful voltagethat can
cause extremelydangerouselectricalshock. Avoidcontact
with bare wires, terminals, etc. Neverpermitany unquali-
fied personto operate or service the generator.
• Never handle any kind of electrical cord or device while
standing in water, while barefoot or while hands or feet are
wet. Dangerous electrical shock will result.
• The National ElectricCode requires the frame and exter-
nal electrically conductive parts of generator be properly
connected to an approved earth ground. Local electrical
codes may alsorequire proper grounding ofthe generator.
Consult with a localelectricianfor grounding requirements
in your area.
• Use a ground fault circuit interrupter in any damp or highly
conductive area (such as metal decking or steel work).
• Donot use any worn, bare, frayed or otherwise _ma_ed
electricalcord sets with the generator. Using any defective
cord set may result in electrical shock or damage to equip-
ment and/or property
• Operategenerator only on level surfaces and where it will
not be exposed to excessive moisture, dirt, dust or corro-
sive vapors.

local codes may vary widely. Consult with a local electrician
for grounding requirements in your area. Besure to keep the
ground wireattached while you connect the electrode.
Properly grounding the generator helps prevent electrical
shock ifa ground fault conditions exists in the generator or in
connectedelectricaldevices, Propergroundingalso helpsdis-
sipate static electricity, which often builds up in ungrounded
devices.
BEFORESTARTINGTHE ENGINE
Perform the following tasks beforetrying to start the genera-
tor engine:
• ADD ENGINEOIL BEFOREINITIAL START
Removeone ofthe yellow Oil Fill Caps (Figure 2 on page 4)
andadd engineoiluntiloillevelis atpointofoverflowing,Check
engine oillevelbeforestarting each time thereafter. Ifoil level
is belowpoint of overflowing, fill to proper level.
GROUNDINGTHE GENERATOR
The National Electric Code requires the frame and external
electrically conductive parts of generator be properly con-
nectedtoapproved earth ground. Localelectrical codes may
also require proper grounding of the unit. Forthat purpose,
a GROUNDINGWINGSCREW (Figure 1) isprovided onthe
cradleframe.

NOTE: The generator's revolving field rides on a pre-lubri-
cared and sealed ball bearing that requires no additional
lubrication forthe life of the bearing.

OPERATINGTHE GENERATOR
• STARTINGTHE ENGINE
o Disconnectall electrical loads from the generator.
• Openthe fuel shut-off valve.
• Referto the engine manual.
Extended Life Generator
Engine-generatorruns at high governedspeedwith Idle Con-
trol Switch ON(-) only when an electrical load is connected
to the generator and turned on. When the electrical load is
disconnected,an Electromagnetisenergized topulltheengine
throttle control against its idle stop. Engine then runs at
reduced(idle) speed.
The Electromagnet cannot be energized with Idle Control
Switch OFF,since its power circuit is open. Engine runs at
high governed speed (about 3600 rpm) whether load(s) are
connected or not.
• ADJUSTING IDLE CONTROL
Youcan adjust and set the idle Control on the engine-gener-
atoras follows:
o With unit running and warmed up, turn the idle control bolt
clockwise(fasterspeed),or counterclockwise(slowerspeed)
until the engine speed is between 40 and 45 Hz. (2400 ~
2700 rpm). See Figure 3.

• LocktheIdleControlJam Nutagainsttheidlecontrolbracket,
while making certain the engine speed is still within the
range of 40 to 45 Hz.
NOTE: Engine idlespeeds of less than 40 Hz could cause
the engine to stall if you applysudden block loads.
• CHARGING A BATTERY

12-volt automotive or utility style storage battery. Do not use
the unitto charge any 6-volt batteries. Do not use the unit to

volt batteries, proceed as follows:
• Checkfluid levelinall batterycells. If necessary, add ONLY
distilled waterto cover separators in battery cells. DO NOT
USETAP WATER.
• If the battery is equipped withvent caps, make sure they
are installed and are tight.
• If necessary, clean battery posts or terminals.

• Start engine (see"Starting the Engine" on Page4). Letthe
engine run while battery recharges.
• When battery has charged, shut down engine (see "Stop-

NOTE: Use an automotive hydrometerto test battery state
of charge and condition. Followthe hydrometer manufactur-

CORDSETSFOR RECEPTACLES
This generatorisequippedwiththe following receptacles:
• TWO 120-VOLT,15 AMP RECEPTACLES
Each receptacle is protected against overloadby a 15-amp
push-to-rasettype f circuitbreaker. Use each receptacleto
operate t20 volts; singlephase 60 Hz, AC electrical loads
requiringupto 1800watts (1.8kW) at 15ampsof current.Use
cord setsthat are rated 125 volts at 15 amps (orgreater).
• 120-VOLT,30 AMP LOCKINGTYPE
RECEPTACLE
Use NEMA L5-30Ptype plugwiththis receptacle. Generac
providesa plug as part ofthe optional accessoriesthatgo with
the4000 XL (Part # 84894). Connect a 3-wire cord set rated
125 volts at 30 AC amps to the ptug according to Figure 6.
Use this receptacle to operate 120 volts AC, 60 Hz, single
phase loads requiring up to 4000 watts(4.0 kW) of power at
30 AC amps. The outlet is protected by a 30 amp push-to-
reset circuit breaker.

orderonefrom Generec(Part# 84893).Connect a 4-wira cord
set rated 250 volts at 20 AC amps (or greater) according to
Figure 7. You can use the same 4-wire cord if the you plan
only to runa 120 voltsload. This receptacle powers 120/240
voltsAC,60 Hz,singlephase loads requiring upto 4000 watts

• GENERATORMAINTENANCE
Generator maintenance consistsof keeping the unit clean
and dry. Operate and store the unit in a clean dry environ-
ment where it will not be exposed to excessive dust, dirt,
moisture or any corrosive vapors. Cooling air slots in the
generator mustnot become cloggedwith snow,leaves or any
other foreign material.
Check the cleanlinessof the generatorfrequently andclean
when dust, dirt, oil, moisture or otherforeign substances are
visible on itsexterior surface.
NOTE: We DONOTrecommendusinga gardenhoseto clean
generator.Watercanenterenginefuelsystemandcauseprob-
lems. Inaddition, if water enters generatorthrough cooling
airslots, someof thewater willberetainedin voidsand cracks
of the rotor and stator winding insulation. Water and dirt
buildup on the generator internal windings will eventually
decrease the insulationresistanceof these windings.
• TO CLEAN THE GENERATOR
• Use a damp cloth to wipeexterior surfaces clean.
• Soft,bristle brush may beused to loosen caked on dirt or
oil.
, A vacuum cleaner may be used to pick up loose dirt and
debris.
• Lowpressureair(notto exceed25 psi) maybe usedto blow
awaydirt. Inspect cooling air slots and openingon gener-
ator. Theseopeningsmustbekeptclean and unobstructed.
SERVICEAND ADJUSTMENTS
Referto engine manual for information.
STORAGEINSTRUCTIONS

and allowedto runatleast30 minutes. Ifthis cannot be done
and you must store the unit for more than 30 days, use the
following guidelines to prepare itfor storage.
• GENERATOR
• Clean the generator as outlinedin "ToClean the Genera-
tor'.
