MAINTENANCE
WARNING!
Running the engine with a dirty, damaged or missing air filter element can result in danger to
the operator and cause the engine to wear out prematurely.
NOTE:
Make sure to drain your carburetor before
storing the generator for long periods of time.
DRAINING THE CARBURETOR
Drain the carburetor after every use and before storing
the generator
(refer to page 27, Table 4). Draining the
carburetor can help prevent build-up and blockages caused
by stagnant fuel inside of the carburetor.
NOTE:
We recommend draining the carburetor after every
session in which gasoline was used. If you drained the car-
buretor previously, and only used LPG as fuel, you do not
need to drain the carburetor.
1. Prepare an approved gasoline-storage container under
the carburetor to collect the drained fuel.
2. The carburetor can be accessed from the backside of
the generator between the engine and the air filter. To drain
the carburetor, open up the carburetor drain screw with a
Phillips-head screwdriver (not included) and drain out any
gasoline that has built up inside. See Fig. 19.
3. Once the fuel has drained, close the drain screw.
INSPECTING/CLEANING THE AIR FILTER
Inspect and clean the air filter every 50 hours of operation
(refer to page 27, Table 4). Routine maintenance of
the air filter helps maintain proper airflow to the carburetor. Occasionally check that the air filter is free of excessive
dirt. Clean air filter more frequently in dirty or dusty conditions.
1. Remove the air filter cover by unscrewing the cover lock
knob at the bottom of the air filter cover. See Fig. 20.
2. Remove the foam, sponge-like air filter element from the
casing. Wipe excessive oil and any dirt from inside of the
air filter casing.
3. Check the foam, sponge-like air filter element.
a)
Good elements
can be washed in soapy water. Dry
the element in clean cloth (do not twist it). Add a few
drops of engine oil to the air filter element and spread it
evenly. A small amount of oil left in the element is normal
and necessary for the engine to work properly.
b)
Damaged elements
should be replaced with a new
one. Replacement air filters can be purchased from

by searching part number
GN400i-1002.
4. Reinstall the air filter element and air filter cover.
