to the rubber seal.

and 24hp Engines Only)
Do not clean the secondary filter, replace it.
Important: Never attempt to clean the secondary
filter. If the secondary filter is dirty, then the

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 secondary filter (22hp and 24hp Engines Only)
is being replaced, carefully slide it into the filter body
(Figure 44).
3. Carefully slide the primary filter over the secondary
filter (Figure 44). Ensure that it is fully seated by
pushing on the outer rim of the filter while installing
it.
