Maintenance
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.
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.

NOTE:
3.4.6 REPLACING THE SPARK PLUG
See Engine Specifications for recommended spark plug. 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 0.70-0.80 mm (0.028-0.031 in.).
Install the correctly gapped spark plug into the cylinder head
(Figure 13).

3.4.7 BATTERY REPLACEMENT
The battery shipped with the generator has been fully charged.
A battery may lose some of its charge when not in use for
prolonged periods of time. If the battery is unable to crank
the engine, plug in the 12V charger included in the accessory
box (see the Charging a Battery section). RUNNING THE
GENERATOR DOES NOT CHARGE THE BATTERY. Refer to the
Battery Cable Connection section.
