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.

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 the 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 (Figure 6).

3.3.5 CHANGING THE OIL

Change the oil after the first 20 hours of operation, then every 50
hours thereafter. 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:
1. See the KNOW THE GENERATOR section for component
location.
2. Clean area around oil drain plug.
3. Remove oil drain plug from engine and oil fill plug to drain oil
completely into a suitable container.
4. When oil has completely drained, install oil drain plug and tighten
securely.
5. Fill engine with recommended oil. (See "Before Starting the
Generator" for oil recommendations).
6. Wipe up any spilled oil.
7. Dispose of used oil at a proper collection center.

3.3.6 REPLACING THE SPARK PLUG

Use spark plug F6TC, NGK BP6IS or Champion RN11YC. Replace
the plug once each year. This will help the engine start easier and
run better.
1. Stop the engine and pull the spark plug wire off of the spark plug.
2. Clean the area around the spark plug and remove it from the
cylinder head.
3. Set the spark plug's gap to 0.76 mm (0.030 in.). Install the
correctly gapped spark plug into the cylinder head and torque to
15 ft/lbs. (Figure 8).
