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".
Once a year replace the spark plug(s) and replace the air filter.
A new spark plug(s) and a 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
the negative cable from the battery (if equipped). Also
disconnect spark plug wire(s) from spark plug(s) and
keep wire(s) away from spark plug(s).
NOTE:
NOTE:

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 AND OIL FILTER

Change the oil and oil filter 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.
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 (or dipstick)
to drain oil completely into a suitable container.
3. When oil has completely drained, install oil drain plug and
tighten securely.
4. Place a suitable container beneath the oil filter and turn filter
counterclockwise to remove. Discard according to local
regulations.
5. Coat gasket of new filter with clean engine oil. Turn filter
clockwise until gasket contacts lightly with filter adapter. Then
tighten an additional 3/4 turn.
6. Fill engine with recommended oil. (See "Before Starting the
Generator" for oil recommendations).
7. Wipe up any spilled oil.
8. Replace oil fill plug (or dipstick).
9. Dispose of used oil at a proper collection center.

3.4.6 REPLACING THE SPARK PLUG(S)

See Engine Specifications for recommended spark plug(s).
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(s) off of the spark
plug(s).
2. Clean the area around the spark plug(s) and remove it from the
cylinder head(s).
3. Set the spark plug's gap to 0.70-0.80 mm (0.028-0.031 in.).
Install the correctly gapped spark plug(s) into the cylinder
head(s) (Figure 21).
