3.2.3 EMISSIONSINFORMATION
The Environmental Protection Agency (EPA) requires that this
generator comply with exhaust emission standards. The engine
used in this generator is certified to meet the applicable EPA
emission levels. It is important to follow the maintenance
specifications provided in this manuals to ensurethat the engine
complies with the applicableemission standardsfor the duration
of the engine'slife. The emissioncontrol system on this generator
consists of the following:
* Air Induction system * Ignition System
Intake Pipe/Manifold - Spark Plug
Air Cleaner _ Ignition Coil
* Exhaust System * Fuel System
Exhaustmanifold _ Carburetor
Muffler
The Emissions Compliance Period referred to on the Emissions
Compliance Label indicates the number of operating hours
for which the engine has been shown to meet EPA emission
requirements.
3.3 GENERAL RECOMMENDATIONS
Thewarranty of the generatordoes not cover items that have been
subjected to operator abuse or negligence.To receive full value
from the warranty, the operator must maintain the generator as
instructed in this manual.
Some adjustments will need to be made periodically to properly
maintain the generator.
All adjustments in the Maintenancesection of this manual should
be made at leastonce each season.Followthe requirementsin the
"MaintenanceSchedule".
NOTE:
Once a year replace the spark plug and replace the air filter.
A new spark plug and clean air filter assure proper fuel-air
mixture and help the engine run better and last longer.
3.3.1 GENERATOR M AINTENANCE
Generatormaintenanceconsists of keepingthe unit clean and dry.
Operateand store the unit in a clean dry environmentwhere it will
not be exposedto excessivedust, dirt, moisture or any corrosive
vapors. Cooling air slots in the generator must not become
clogged with snow, leaves,or any other foreign material.
Checkthe cleanlinessof the generatorfrequently and clean when
dust, dirt, oil, moisture or other foreign substances are visible on
its exteriorsurface.
A.CAUTION!
_h Never insert any object or tool through the air
cooling slots, even if the engine is not running.
NOTE:
DO NOTuse a garden hoseto clean generator. Water can enter
the engine fuel systemand causeproblems.In addition, if water
enters the generator throughcoolingair slots,some water will
be retainedin voidsand crevicesof the rotorand statorwinding
insulation. Water and dirt buildup on the generator internal
windingswill eventually decreasetheinsulationresistanceof
these windings.
3.3.2 TOCLEANTHEGENERATOR
* Use a damp cloth to wipe exteriorsurfaces clean.
* A soft, bristle brush may be used to loosen caked on dirt, oil,
etc.
* A vacuum cleanermay be usedto pick up loose dirt and debris.
* Low pressure air (not to exceed 25 psi) may be used to
blow away dirt. Inspect cooling air slots and openings
on the generator. These openings must be kept clean and
unobstructed.
3.3.3 ENGINE MAINTENANCE
/_When working on the generator, always
disconnect spark plug wire from spark plug and
keep wire away from spark plug.
3.3.4 CHECKING OILLEVEL
Seethe "Before Starting the Generator"sectionfor informationon
checkingthe oil level. The oil levelshould be checkedbefore each
use, or at least every eight hours of operation. Keepthe oil level
maintained.
3.3.5 CHANGING THEOIL
Changethe oil after every 100 hours. If running this unit under
dirty or dusty conditions, or in extremely hot weather,changethe
oil more often.
,&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.
Use thefollowinginstructions to changethe oil after the engine
coolsdown:
* Cleanarea around oil drain plug.
* Removeoil drain plug from engine and oil fill plug to drain oil
completely into a suitable container.
* When oil has completely drained, install oil drain plug and
tighten securely.
* Fill engine with recommended oil. (See "Before Starting the
Generator"for oil recommendations).
