3.2.3 EMISSIONS INFORMATION

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 ensure that the engine
complies with the applicable emission standards for the duration
of the engine's life. The emission control system on this generator
consists of the following:
• Air Induction system
~ Intake Pipe/Manifold
~ Air Cleaner
• Exhaust System
~ Exhaust manifold
~ 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

The warranty of the generator does 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 Maintenance section of this manual should
be made at least once each season. Follow the requirements in the
"Maintenance Schedule".
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 MAINTENANCE

Generator maintenance consists of keeping the unit clean and dry.
Operate and store the unit in a clean dry environment where it will
not be exposed to excessive dust, dirt, moisture or any corrosive
vapors. Cooling air slots in the generator must not become
clogged with snow, leaves, or any other foreign material.
Check the cleanliness of the generator frequently and clean when
dust, dirt, oil, moisture or other foreign substances are visible on
its exterior surface.
• Ignition System
~ Spark Plug
~ Ignition Coil
• Fuel System
~ Carburetor
NOTE:
Never insert any object or tool through the air

cooling slots, even if the engine is not running.
DO NOT use a garden hose to clean generator. Water can enter
the engine fuel system and cause problems. In addition, if water
enters the generator through cooling air slots, some water will
be retained in voids and crevices of the rotor and stator winding
insulation. Water and dirt buildup on the generator internal
windings will eventually decrease the insulation resistance of
these windings.

3.3.2 TO CLEAN THE GENERATOR

• Use a damp cloth to wipe exterior surfaces clean.
• A soft, bristle brush may be used to loosen caked on dirt, oil,
etc.
• A vacuum cleaner may be used to 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 OIL LEVEL

See the "Before Starting the Generator" section for information on
checking the oil level. The oil level should be checked before each
use, or at least every eight hours of operation. Keep the oil level
maintained.

3.3.5 CHANGING THE OIL

Change the oil after every 100 hours. If running this unit under
dirty or dusty conditions, or in extremely hot weather, change the
oil more often.
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 the following instructions to change the oil after the engine
cools down:
• Clean area around oil drain plug.
• Remove oil 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).
