1. Open the hood.
2. Check the air filter-blockage indicator ( Figure

Replacing the Primary Air
Filter
Service Interval: Every 500 hours
Check the air-cleaner body for damage that could
cause an air leak. Replace the air-cleaner body if
damaged. Check the whole intake system for leaks,
damage, or loose hose clamps.
Note:
Service the primary air filter when the
filter-blockage indicator ( Figure 49 ) is red. Changing
the air filter frequently increases the chance of dirt
entering the engine when the filter is removed.
Important:
Be sure that the cover is seated
correctly and seals with the air-cleaner body.
1. Before removing the air-filter cover, use low
pressure air (40 psi, clean and dry) to help
remove large accumulations of debris packed
outside of the filter canister.
Note:
This cleaning process prevents debris
from migrating into the intake when the filter is
removed.
Important:
Avoid using high-pressure air
which could force dirt through the filter into
the intake tract.

checking the sealing end of the filter and the
body.
Important:
Do not use a damaged element.
5. Insert the new filter by applying pressure to the
outer rim of the element to seat it in the canister.
Important:
Do not apply pressure to the
flexible center of the filter.
