DRAINING THE CARBURETOR
Drain the carburetor after every use and before storing
the generator (refer to page 23, Table 4). Draining the
carburetor can help prevent build-up and blockages caused
by stagnant fuel inside of 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 and drain out any gasoline that
has built up inside. See Fig. 16.
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 23, 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 unscrewing the cover lock
knob at the bottom of the air filter cover. See Fig. 17.
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 wen-
products.com by searching part number P54178-1.
4. Reinstall the air filter element and air filter cover.
MAINTENANCE
NOTE: Make sure to drain your carburetor before
