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. Using a Phillips-head screwdriver, unscrew the top two
screws (Fig. 19 - 1) and remove the service panel on the op-
posite side of the recoil starter.
2. Take the cover off of the air cleaner (Fig. 21). Remove the
sponge-like air filter element from the casing. Wipe excessive
oil and any dirt from inside of the air filter casing.
3. Check and clean the foam air filter element. 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.
If the air filter element has been damaged, replace it with a new one. Replacement air filters can be ordered from
wenproducts.com by searching part no. 56380i-1001B.1.
4. Reinstall the air cleaner element, air cleaner cover and service panel.
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. 22).
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.
56380i-1115).
4. Reinstall the spark arrestor in the muffler and secure it in
place with the screws.
