AIR FILTER MAINTENANCE
Check every 50 hours of operation (refer to Recommended Maintenance Schedule).
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
To inspect and clean the air filter:
1. Remove the air filter cover (Fig. 17) by undoing the clasps at the
top and bottom of the air filter cover.
2. 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). A small amount of oil left in the element is normal and necessary
for the engine to work properly.
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. DF475-166.1.
4. Reinstall the air filter element and air filter cover.
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.
SPARK ARRESTOR MAINTENANCE
The spark arrestor is located outside the muffler, which gets very hot
during operation. Allow the engine to cool completely before servic-
ing the spark arrestor. To inspect and clean the spark arrestor:
1. Remove the screws holding the cover plate which retains the end
of the spark arrestor to the muffler (Fig. 18 - 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.
4. Reinstall the spark arrestor in the muffler and secure it in place with
the screws.
