3. Clean the inside of the air cleaner cover with
compressed air.
4. Gently slide the primary filter out of the air cleaner
body (Figure 5). Avoid knocking the filter into the
side of the body. Do not remove the safety filter,
unless you intend to replace it as well.
5. Inspect the primary filter for damage by looking
into the filter while shining a bright light on the
outside of the filter. Holes in the filter will appear
as bright spots. If the filter is damaged discard it.
Never attempt to clean the safety filter. If
the safety filter is dirty, then the primary filter is
damaged and you should replace both filters.
Cleaning the Primary Filter
Blow compressed air from the inside to the outside of
the primary filter.
Do not exceed 100 psi and keep the
hose at least 2 inches from the filter. Replace air filters
if they are damaged or cannot be cleaned.
Installing the Filters
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 safety filter is being replaced, carefully slide
it into the filter body (Figure 5).
3. Carefully slide the primary filter over the safety
filter (Figure 5). Ensure that it is fully seated by
pushing on the outer rim of the filter while
installing it.
Do not press on the soft inside area of
the filter.
4. Install the air cleaner cover with the side indicated
as UP facing up and secure the latches (Figure 5).
