Inspecting the Filters
1. Inspect the inner filter. If it is dirty, replace both
the inner and outer filters.
Important:
Do not attempt to clean the inner
filter. If the inner filter is dirty, then the outer
filter is damaged.

into the filter while shining a bright light on the
outside of the filter. If the outer filter is dirty, bent,
or damaged, replace it.
Note:
Holes in the filter appear as bright spots.
Do not clean the outer filter.
Installing the Filters
Important:
To prevent engine damage, always
operate the engine with both air filters and the
cover installed.
1. If you are installing new filters, check each filter
for shipping damage.
Note:
Do not use a damaged filter.
2. If you are replacing the inner filter, carefully slide
it into the filter body (
