FILTER ELEMENTS - CLEANING AND INSPECTION

The air cleaner is a dual element
type.
Clean the primary (outer) element only. Do
not attempt to clean the secondary (Inner)
element. If there is visible dirt on the secondary
element, replace both primary and secondary
elements. See "Filter Elements - Replacement" for
normal change Interval.
To clean air filter element:
1. Remove element from air cleaner canister.
