Servicing the Primary Filter
• If the primary filter is dirty, bent, or damaged,
replace it.
• Do not clean the primary filter.
Servicing the Inner Filter
Replace the inner filter, never clean it.
Important: Never attempt to clean the safety filter.
If the safety filter is dirty, then the primary filter is
damaged. Replace both filters.
Installing the Filters
Important: To prevent engine damage, always
operate the engine with both air filters and cover
installed.
1. If installing new filters, check each filter for shipping
damage. Do not use a damaged filter.
2. If the inner filter is being replaced, carefully slide it
into the filter body (Figure 49).
3. Carefully slide the primary filter over the inner filter
(Figure 49).
Note: Ensure that the primary filter is fully seated
by pushing on its outer rim while installing it.
Important: Do not press on the soft inside area
of the filter.
4. Position the air cleaner cover so that the breather
valve does not interfere with the throttle mechanism
(Figure 50).
