2. Before removing the filter, use low pressure air (40 psi,
clean and dry) to help remove large accumulations of
debris packed between the outside of the primary filter
and the canister.
Important
Avoid using high pressure air which could
force dirt through the filter into the intake tract. This
cleaning process prevents debris from migrating into the
intake when the primary filter is removed.
3. Remove and replace the primary filter.
Note: Cleaning of the used element is not recommended
due to the possibility of damage to the filter media.
4. Inspect the new filter for shipping damage, 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.

cover. Remove the rubber outlet valve from the cover,
clean the cavity, and replace the outlet valve.

downward position–between approximately 5:00 to
7:00 when viewed from the end.
