Bon't Overload Generator
You must make sureyour generator cansupply enough
rated (running) and surge (starting) watts for the items you
will power at the same time. Followthese simple steps:
1. Selectthe itemsyou will power at the same time.
2. Totalthe rated(running) watts ofthese items. This is the
amount of poweryour generatormust produceto keep
your items running. SeeWattageReferenceGuide.
3. Estimatehow many surge (starting) watts you will need.
Surge wattageis the short burst of power neededto
start electric motor-driven tools or appliancessuch asa
circular saw or refrigerator. Becausenot all motors start
atthe sametime, total surgewatts can be estimatedby
adding only the item(s) with the highest additionalsurge
watts to the total ratedwattsfrom step 2.

Power Management
To prolong the life of your generatorand attacheddevices, it
is important to take carewhen addingelectrical loadsto your
generator. Thereshould be nothing connected to the
generator outlets before starting its engine.Thecorrect and
safe way to managegeneratorpower isto sequentiallyadd
loads asfollows:
1. With nothing connectedto the generator,start the
engine asdescribed in this manual.
2. Hug in andturn on the first load, preferablythe largest
load you have.
3. Permit the generatoroutput to stabilize (engine runs
smoothly and attacheddeviceoperates properly).
4. Hug in andturn on the next load.
5. Again, permit the generatorto stabilize.
6. Repeatsteps 4 and 5 for eachadditional load.
NEVERadd more loadsthan the generatorcapacity.Take
special careto consider surge loads in generator capacity,as
described above.

General Recemmendatiens
Regular maintenancewill improve the performance and
extendthe life of the generator. Seeany authorizeddealer for
service.
Thegenerator's warranty doesnot cover items that have
been subjectedto operator abuseor negligence.To receive
full valuefrom the warranty, the operator must maintainthe
generator asinstructed in this manual.
Someadjustments will needto be made periodically to
properly maintain your generator.
All serviceand adjustments should be made at bast once
eachseason.Follow the requirementsin the Maintenance
Schedulechart above.
HOTICE Oncea year you should cleanor replacethe spark
plug and replacethe air filter. A new spark plug and cleanair
filter assure proper fueloairmixture and help your engine run
better and last longer.
Emissiens Centrei
Maintenance, replacement, er repair ef the emissiens

However,to obtain "no charge" emissions control service,
the work must be performed by a factory authorized dealer,
Seethe Emissions !@rranty,
Generater Maintenance
Generatormaintenanceconsists of keepingthe unit clean
and dry. Operateand store the unit in a clean dry
environment where it will not be exposedto excessivedust,
dirt, moisture, or any corrosive vapors. Coolingair slots in
the generator must not become cloggedwith snow, leaves,
or any other foreign material.
HOTICE DONOTusewater or other liquids to clean
generator. Liquids canenter engine fuel system, causing
poor performance and/or failure to occur, in addition, if
liquid enters generator through cooling air slots, some of the
liquid will be retainedin voids and cracks of the rotor and
stator winding insulation. Liquid and dirt buildup on the
generator internalwindings will eventuallydecreasethe
insulation resistanceof these windings.
Cleaning
Daily or before use, look around and underneaththe
generatorfor signs of oil or fuel leaks.Cleanaccumulated
debris from inside and outside the generator. Keepthe
linkage, spring and other engine controls clean. Keepthe
areaaround and behind the muffler free from any
combustible debris, inspect cooling air slots and openings
on generator, Theseopenings must be kept cleanand
unobstructed.
Engine parts should be kept cleanto reducethe risk of
overheating and ignition of accumulateddebris:
o Use a damp cloth to wipe exterior surfaces clean.
HOTICE improper treatment of generator could damage it
and shorten its life.
o DO NOTexposegenerator to excessivemoisture, dust, dirt, or
corrosive vapors.
o DONOTinsert any objects through cooling slots.
o Use a soft bristle brush to loosen cakedon dirt or oil.
o Use a vacuum cleanerto pick up loose dirt and debris.

We recommendthe useof Briggs & Stratton Warranty
Certified oils for best performance. Otherhigh-quality
detergent oils are acceptableif classified for serviceSF, SG.
SH, SJ or higher. DONOTuse specialadditives.
Outdoor temperatures determine the proper oil viscosity for
the engine. Usethe chart to selectthe best viscosity for the
outdoor temperature rangeexpected.
Checking Oil Level
Oil levelshould be checked prior to each useor at bast
every 8 hours of operation. Keepoil levelmaintained.
1. Make sure generatoris on a levelsurface.
2. Cleanarea around oil fill. removeoil cap/dipstick and

° Cleanthe generator as outlined in Cleaning.
° Checkthat cooling air slots and openingson generator
are open and unobstructed.
LongTerm Storage instructions
Fuelcan becomestale when stored over 30 days.Stab fuel
causesacid and gum deposits to form in the fuel system or
on essentialcarburetor parts. To keepfuel fresh, use Briggs
& Stratton FRESHSTART@fuel stabilizer, availableasa
liquid additive or a drip concentrate cartridge.
Thereis no needto drain gasolinefrom the engine if a fuel
stabilizer is added according to instructions. Runthe engine
for 2 minutesto circulate the stabilizerthroughout the fuel
system. The engine andfuel canthen be stored up to
24 months.
if gasoline in the engine hasnot beentreated with a fuel
stabilizer, it must be drained into an approvedcontainer. Run
the engine until it stops from lack of fuel. The useof a fuel
stabilizer in the storage container is recommendedto
maintain freshness.
