AIR FILTER MAINTENANCE
Check every 50 hours of operation (refer to Table 4 - Recommended Maintenance Schedule).
Routine maintenance of the air filter helps maintain proper airflow to the carburetor. Occasionally check that the air
cleaner is free of excessive dirt.
To inspect and clean the air filter:
1. Remove the air filter cover (Fig. 20 - 1) by unscrewing the
cover lock knob (Fig. 20 - 2) at the bottom of the air filter
cover.
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 neces-
sary 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 DF8000X-137.
4. Reinstall the air filter element and air filter cover.
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.
SPARK ARRESTOR MAINTENANCE
Inspect and clean the spark arrestor every 100 hours of operation. The spark arrester is located outside the muffler,
which gets very hot during operation. Allow the engine to cool completely before servicing the spark arrester. To
inspect and clean the spark arrester:
1. Remove the two Phillips-head screws that secure the spark
arrestor to the muffler (Fig. 21 - 1).
2. Remove the spark arrestor screen.
3. Carefully clean and remove the carbon deposits from the
spark arrestor screen with a wire brush. Replace the spark
arrestor if it is damaged (replacement spark arrestors can be
purchased from wenproducts.com by searching the part no.
DF8000X-027.1).
4. Reinstall the spark arrestor in the muffler and secure it in
place with the screws.
