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 (
) is red. Changing
the air filter frequently increases the chance of dirt
entering the engine when the filter is removed.
Important:
Ensure that the cover is seated
correctly and seals with the air-cleaner body.
1.
Prepare the machine for maintenance; refer to
Preparing the Machine for Maintenance (page

.
2.
Unlatch and open the hood.
3.
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.

Important:
Do not clean and reuse a used
element because of possible damage to the
filter element.
6.
Inspect the new filter for shipping damage,
checking the sealing end of the filter and the
body.
Important:
Do not use a damaged element.
7.
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.
8.
Clean the dirt ejection port located in the air-filter
cover. Remove the rubber outlet valve from the
cover, clean the cavity in the valve, and install
the outlet valve into the air-filter cover.
9.
Align the dirt ejection port air-filter cover between
3 o’clock to 5 o’clock when viewed from the end,
assemble the cover to the canister, and secure
the cover.
10.
Close and latch the hood.
Replacing the Safety Filter
The air filter has a secondary, safety filter element
inside the primary air filter to prevent dislodged
dust and other items from entering the engine while
changing the main element.
Replace the safety filter; never clean it.
Important:
Never attempt to clean the safety
filter. If the safety filter is dirty, then the primary
filter is damaged. Replace both filters.
