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.
3.4.1 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.
n
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.

NOTE:
3.4.3 ENGINE MAINTENANCE
When working on the generator, always 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 every 100 hours. If running this unit under dirty
or dusty conditions, or in extremely hot weather, change the oil more
often.
n
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. Clean area around oil drain plug.
2. Remove oil drain plug from engine and oil fill plug to drain oil
completely into a suitable container.
3. When oil has completely drained, install oil drain plug and tighten
securely.
4. Fill engine with recommended oil. (See "Before Starting the
Generator" for oil recommendations).
5. Wipe up any spilled oil.
6. Dispose of used oil at a proper collection center.
3.4.6 REPLACING THE SPARK PLUG
Use Champion N9YC spark plug or equivalent. Replace the plug
every 200 hours. 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 0.70-0.80 mm (0.028-0.031 in.). Install
the correctly gapped spark plug into the cylinder head (Figure
13).
