3.3.3 EMISSIONS INFORMATION

The Environmental Protection Agency (and California Air Resource
Board for generators certified to CA standards) require(s) that
this generator comply with exhaust and evaporative emission
standards. Locate the emissions compliance decal on the engine
to determine what standards the generator meets. This generator
is certified to operate on gasoline. The emission control system
includes the following components (if equipped):
• Air Induction System
Intake Pipe / Manifold
Air Cleaner
• Fuel System
Carburetor
Fuel Tank / Cap
Fuel Lines
Evaporative Vent Lines
Carbon Canister

3.4 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".
• Ignition System
~ Spark Plug
~ Ignition Module
• Exhaust System
~ Exhaust Manifold
~ Muffler
~ Pulsed Air Valve
~ Catalyst
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.

3.4.1 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.
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.

3.4.2 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.

3.4.3 ENGINE MAINTENANCE

 When working on the generator, always
disconnect negative cable from battery. Also
disconnect spark plug wire from spark plug and
keep wire away from spark plug.

3.4.4 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.

3.4.5 CHANGING THE OIL

Change the oil after the first 30 hours of operation. Change the
oil every 100 hours or every season thereafter. If running this
unit under dirty or dusty conditions, or in extremely hot weather,
change the oil more often.
