operate the engine with both air filters and the

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

filter (Figure 46).

Ensure that the primary filter is fully
seated by pushing on the outer rim while

damage the engine.

for all moving parts to stop before leaving the

oil has had time to drain into the sump.
