3.4 GENERALRECOMMENDATIONS
Thewarranty of the generatordoes not cover itemsthat havebeen
subjected to operator abuse or negligence.To receivefull value
from the warranty, the operator must maintain the generator as
instructed inthis manual.
Some adjustments wilt need to be made periodically to properly
maintainthe generator.
All adjustments in the Maintenancesection of this manual should
be madeat leastonce eachseason. Followthe requirementsinthe
"MaintenanceSchedule".
NOTE:
Once a year replace the spark plug and replace the air filter.
A new spark plug and clean air filter assure properfuel-air
mixtureand helpthe engine run better and last longer.
3.4.1 GENERATORMAINTENANCE
Generatormaintenanceconsists of keepingthe unit clean and dry.
Operateand storethe unit in a clean dry environmentwhereit will
not be exposedto excessive dust, dirt, moisture or any corrosive
vapors.Coolingair slots in the generatormust not becomeclogged
with snow, leaves,or any otherforeign material.
Checkthe cleanlinessof the generatorfrequently and clean when
dust, dirt, oil, moisture or other foreign substances arevisible on
its exteriorsurface.
,&,CAUTION!
,_ Never insert any object or tool through the air
cooling slots, even if the engine is not running.
NOTE:
DO NOTusea gardenhose to cleangenerator. Water canenter
theenginefuel systemand causeproblems,in addition, ifwater
enters thegenerator throughcoolingair slots,somewaterwill
be retainedin voidsand crevicesof the rotorand stator winding
insulation.Water and dirt buildup on the generator internal
windingswill eventually decreasetheinsulationresistanceof
thesewindings.

* Usea damp cloth to wipe exteriorsurfaces clean.
. A soft, bristle brush may be usedto loosen caked on dirt, oil,
etc.
. A vacuumcleanermay be usedto pick up loose dirt anddebris.
. Low pressure air (not to exceed 25 psi) may be used to
blow away dirt. Inspect cooling air slots and openings on the
generator.Theseopeningsmust bekeptcleanandunobstructed.
3.4.3 ENGINEMAINTENANCE
When working on the generator, always
disconnect spark plug wire from spark plug and
keep wire away from spark plug.
3.4.4 CHECKINGOILLEVEL
Seethe "BeforeStarting the Generator"sectionfor informationon
checkingthe oil level.The oil level should be checkedbefore each
use, or at least every eight hours of operation. Keepthe oil level
maintained.
3.4.5 CHANGINGTHEOIL
Changethe oil after every 100 hours. If running this unit under
dirty or dusty conditions, or in extremelyhot weather,changethe
oil more often.
,A CAUTION!
,_Hot oil may cause burns. Allow engine to
cool before draining oil. Avoid prolonged
or repeated skin exposure with used oil.
Thoroughly wash exposed areas with soap.

3.4.6 REPLACINGTHESPARKPLUG
Use ChampionN9YCspark plug or equivalent.Replacetheplug
every 200 hours.This will help the engine start easier and run
better.
1. Stop the engineand pull the spark plug wire off of the spark
plug.
2. Cleanthe area aroundthe spark plug and remove it from the
cylinder head.
3. Set the spark plug's gap to 0.70-0.80 mm (0.028-0.031 in.).
Install the correctly gappedspark plug into the cylinder head
(Figure14).
