Servicing the Air-Cleaner Filter
elements
Service Interval: Every 400 hours
Every 400 hours
The air-intake system on this machine is continuously
monitored by an air-restriction sensor that will display
an advisory when the air filter needs to be replaced.
Do not replace the elements until this occurs.
Important:
Replace the secondary filter element
only every 3 primary filter services. Do not remove
the secondary element when cleaning or replacing
the primary element. The inner element prevents
dust from entering the engine when you service
the primary element.
Important:
Do not operate the engine without the
air-cleaner elements as this would allow foreign
material to enter the engine and damage it.
1. Release the latches securing the air-cleaner
cover to the air-cleaner body

2. Remove the cover from the air-cleaner body.
3. Before removing the filter, use low-pressure
air (275 kPa or 40 psi, clean and dry) to help
remove large accumulations of debris packed
between the outside of the primary filter and the
canister.
Note:
Avoid using high-pressure air that could
force dirt through the filter into the intake. This
cleaning process prevents debris from migrating
into the intake when the primary filter is removed.
4. Remove the primary filter
Note:
Do not clean the used element due to the
possibility of damage to the filter media.
Note:
Replace the secondary filter every 3
primary filter services
(Figure 96).

5. Inspect the new filter for shipping damage,
checking the sealing end of the filter and the
body.
Important:
Do not use a damaged element.
6. 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, as this may
damage the filter.
7. Clean the dirt-ejection port located in the
removable cover.
8. Remove the rubber outlet valve from the cover,
clean the cavity, and replace the outlet valve.
9. Install the cover orienting the rubber outlet valve
in a downward position—approximately between
the 5 o'clock and 7 o'clock position when viewed
from the end.
10. Secure the cover latches.
