3. Estimate how many surge (starting) wattsyou will need.

Surge wattageis the short burst of power neededto
start electric motor-driven tools orappliancessuch as a
circular saw or refrigerator. Becausenot all motors start
at the sametime, total surge watts can be estimatedby
adding only the item(s) with the highestadditional surge
watts to the total rated watts from step 2.

Power Mlanagement

To prolong the life of your generatorandattacheddevices, it
is important to take carewhen adding electrical loadsto your
generator. Thereshould be nothing connectedto the
generator outlets before starting its engine.Thecorrect and
safe way to managegenerator power isto sequentiallyadd

loads as follows:

1. With nothing connectedto the generator, start the

engine as describedin this manual.

2. Plug in and turn on the first load, preferably the largest

load you have.

3. Permit the generatoroutput to stabilize (engine runs

smoothly and attacheddeviceoperates properly).

4. Plug inand turn on the next load.

5. Again, permit the generatorto stabilize.

6. Repeatsteps 4 and 5 for eachadditional load.

GeneralRecommendations

Regularmaintenancewill improve the performanceand
extend the life of the generator.Seeany authorized dealer for
service.

Thegenerator's warranty does not cover items that have
been subjectedto operator abuse or negligence.To receive
full value from the warranty,the operator must maintain the
generatoras instructed in this manual.

Someadjustments will needto be made periodically to
properly maintain your generator.

All serviceand adjustments should bemade at least once
eachseason. Follow the requirements inthe Maintenance

Schedulechart above.
NOTE:Oncea year you should cleanor replacethe spark

plug and replacethe air filter. A new spark plug and clean air
filter assure proper fuel-air mixture and help your engine run
better and last longer.

EmissionsControl
Maintenance, replacement,or repair of the emissions

controldevicesandsystemsmay be performedbyany
non-roadengine repair establishmentor individual.

However,to obtain "no charge" emissions control service,
the work must be performed by afactory authorized dealer.

Seethe Emissions Warranty.

GeneratorMaintenance

Generatormaintenanceconsists of keepingthe unit clean
and dry. Operateand storethe unit in a cleandry
environment where it will not beexposedto excessive dust,
dirt, moisture, or any corrosive vapors. Coolingair slots in
the generator must not become clogged with snow, leaves,
or any other foreign material.

NOTE:DO NOTusewater or other liquids to clean generator.
Liquids can enter enginefuel system, causing poor

performanceand/or failure to occur. Inaddition, if liquid
enters generatorthrough cooling air slots, some of the liquid

will be retained in voids and cracks of the rotor and stator
winding insulation. Liquid and dirt buildup on the generator

internal windings will eventuallydecreasethe insulation
resistance of thesewindings.

Cleaning

Daily or before use,look around andunderneath the
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 clean to reducethe risk of

overheating and ignition of accumulateddebris:

• Use a damp cloth to wipe exterior surfaces clean.

NOTICE: Improper treatment of generator can damage it
and shorten its life.

• DONOTexpose generator to excessive moisture, dust, dirt, or
corrosive vapors.

• DONOTinsert any objects through cooling slots.

• Use a soft bristle brush to loosen cakedon dirt or oil.

• Use a vacuum cleanerto pick up loose dirt and debris.

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 minutes to circulate the stabilizerthroughout the fuel
system. Theengineand fuel can then be stored up to

24 months.

If gasoline in the engine hasnot beentreated with a fuel
stabilizer, it must be drained into an approved container. Run
the engineuntil it stops from lack of fuel. The useof a fuel
stabilizer in the storage container is recommendedto

maintain freshness.

ChangeEngineOil

While engineis still warm, drain oil from crankcase.Refill
with recommendedgrade. See Changing EngineOil.

OtherStorageTips:

1. DO NOTstore fuel from one seasonto another unless it
has beentreated as described in Long TermStorage

Instructions.

2. Replacefuel container if it starts to rust. Rust and/or
dirt in fuel can causeproblems if it's used with this

unit.
