3.4.5 CHANGING THE OIL AND OIL FILTER
Change the oil and filter after the first 30 hours of operation. Change the
oil every 100 hours thereafter. If running this unit under dirty or dusty
conditions, or in extremely hot weather, change the oil more often.
Use the following instructions to change the oil after the engine cools
down:
1. Clean area around oil drain hose and plug.
2. Remove oil drain plug from end of hose 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. 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 oil sump with recommended oil. (See “Before Starting the
Generator” for oil recommendations).
7. Wipe up any spilled oil.
8. Dispose of used oil at a proper collection center.
3.4.6 REPLACING THE SPARK PLUGS
Use Champion RC14YC spark plug or equivalent. The correct air gap is
1.01 mm (0.040 in.). Replace the plugs 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 1.01 mm (0.040 in.). Install the correctly
gapped spark plug into the cylinder head.

3.5 SERVICE AIR CLEANER
The engine will not run properly and may be damaged if using a dirty
air cleaner. Clean or replace the air cleaner paper filter every 200 hours
or once a year. Clean or replace more often if operating under dusty
conditions. Clean foam pre-cleaner every month or more often under
dusty conditions.
To clean or replace paper air filter:
1. Remove air cleaner cover and remove paper filter.
2. Clean paper filter by tapping it gently on a solid surface. If the filter is
too dirty, replace it with a new one. Dispose of the old filter properly.
3. Clean air cleaner cover. Next insert new paper filter into the base of
the air cleaner. Re-install air cleaner cover.

3.6 CLEAN SPARK ARRESTOR SCREEN
The engine exhaust muffler has a spark arrestor screen. Inspect and clean
the screen at least once each year (Figure 22). If unit is used regularly,
inspect and clean more often.
NOTE:
If using the generator on any forest-covered, brush-covered or grass-
covered unimproved land, it must equipped with a spark arrestor. The
spark arrestor must be maintained in good condition by the owner/
operator.
Clean and inspect the spark arrestor as follows:
1. Remove the screen retaining bracket by removing the screw.
2. Slide the spark arrestor screen out from the tail pipe.
3. Inspect screen and replace if torn, perforated or otherwise damaged.
DO NOT USE a defective screen. If screen is not damaged, clean it
with commercial solvent.
4. Replace the screen and the retaining bracket.
