8. Screw the new filter on by hand, until its gasket
lightly contacts the oil filter adapter. Then, tighten
the filter an additional 3/4 to one turn.
9. Remove the dipstick, and wipe it dry with a clean,
lint-free cloth. This will be used later to check the
oil level.
10. Remove the oil-fill plug, and slowly add the
proper type and amount of recommended oil (see
"Engine Oil Requirements"). Periodically use the
dipstick to check the oil level and continue to fill
the crankcase until the oil reaches the dipstick
"FULL " mark. DO NOT FILL ABOVE THE "FULL "
MARK.
11. Install the oil-fill plug and the dipstick.
12. Reinstall the air filter.
13. Reattach the front service door or front panel;
make sure the latches are fully engaged and the
bolts are fully tightened.
14. Start the engine, and check for leaks.
Check the oil level and fill to the "FULL " mark,
after checking for leaks. The filter will retain some
oil.

SERVICING THE ENGINE
AIR FILTER
To access the engine air filter (Figure 3.2), remove
the front service door, located beneath the unit, by
retracting the two latches and pivoting the door
downward. Loosen the hose clamp at the base of
the air filter and remove the filter. Place the hose
clamp on the new filter and install it, making sure it
is positioned properly before reattaching the service
door. Make sure the service door latches are fully
engaged.

SPARK ARRESTOR MUFFLER
The exhaust muffler supplied with the generator
is a spark arrestor type. The exhaust mufflers for
recreational vehicle generators do not have a spark
arrestor screen, but are of the more efficient "toroid"
or "swirl" type. To remove carbon and combustion
deposits from the muffler, proceed as follows (see
Figure 3.3):
1. Place the unit above a noncombustible surface,
and ensure that the generator exhaust piping is
cool.
2. Remove the two screws holding the spark arres-
tor access plate to the rear floor pan.
3. Remove the spark arrestor access plate and gas-
ket.
4. Remove the hex pipe cap from the end of the
spark arrestor cleanout pipe.
5. Thread on a 3/8" NPT pipe coupling and pipe
nipple to extend the cleanout pipe at least 10
inches (250 mm) below the rear floor pan; addi-
tional piping may be added to direct the muffler
exhaust away from the cooling air discharge flow
beneath the unit.
Figure 3.3 – Spark Arrestor Muffler Maintenance
6. Start and run the engine for approximately 15
minutes.
7. Shut down the engine, and allow the piping to
cool.
8. Remove the 3/8" NPT coupling and piping.
9. Apply a graphite-base, anti-seize compound to
the cleanout pipe threads.
10. Reinstall the hex pipe cap, spark arrestor access
plate, gasket, and two screws.
The exhaust system of this product gets
extremely hot and remains hot after shutdown.
High grass, weeds, brush, leaves, etc., must
remain clear of the exhaust. Such materials may
ignite and burn from the heat of the exhaust
system.
