MAINTENANCE
DRAINING THE CARBURETOR
Drain the carburetor after every use and before storing the gen-
erator
(refer to page 28, Table 4).
Draining the carburetor can
help prevent build-up and blockages caused by stagnant fuel in-
side of the carburetor.
1. Prepare an approved gasoline-storage container under the
carburetor to collect drained fuel. Close the fuel valve (Fig. 20).
2. The carburetor can be accessed from the backside of the gen-
erator between the engine and air filter. To drain the carburetor,
open up the carburetor drain screw (Fig. 21) with a Phillips-head
screwdriver and drain out any gasoline that has built up inside.
3. Once the fuel has drained, close the drain screw.
NOTE:
Make sure to drain your carburetor before storing the
generator for long periods of time.
INSPECTING / CLEANING THE AIR FILTER
Inspect and clean the air filter every 50 hours of operation (refer
to page 28, 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.
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.
1. Remove the air filter cover by loosening the clasps at the top
and bottom of the air filter cover (Fig. 22 - 1).
2. Remove the foam, sponge-like air filter elements from the
casing. Wipe excessive oil and any dirt from inside of the air
filter casing.
3. Check the foam, sponge-like air filter elements.
a) Good elements can be washed in soapy water. Dry the ele-
ments in clean cloth (do not twist it). Add a few drops of engine
oil to the air filter elements and spread them evenly. A small
amount of oil left in the elements 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
wenproducts.com by searching
part number
GN9500-138.
4. Reinstall the air filter element and air filter elements. The coarse element goes on the inside (toward the carbu-
retor) and the fine element on the outside (toward the air filter cover). Replace the cover.
