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
3. Carefully slide the primary filter over the safety
filter (Figure 56).
Note:
Ensure that the primary filter is fully
seated by pushing on the outer rim while
installing it.
Important:
Do not press on the soft, inside
area of the filter.
4. Install the air-cleaner cover and secure the
latches (Figure 56).
