Inspect the new filter carefully, paying attention to
the inside of the open end, which is the
sealing area. NEVER install a damaged
filter. A new Donaldson radial seal
filter may have a dry lubricant on the
seal to aid installation.

If you're servicing the safety filter, this should be seated into
position before installing the primary filter.
Insert the new filter carefully. Seat
the filter by hand, making certain it is
completely into the air cleaner housing
before securing the cover in place.
The critical sealing area will stretch
slightly, adjust itself and distribute the sealing pressure evenly. To
complete a tight seal, apply pressure by hand at the outer rim of
the filter, not the flexible center. (Avoid pushing on the center of the
urethane end cap.) No cover pressure is required to hold the seal.
NEVER use the service cover to push the filter into place! Using the
cover to push the filter in could cause damage to the housing, cover
fasteners and will void the warranty.
If the service cover hits the filter before it is fully in place, remove
the cover and push the filter (by hand) further into the air cleaner
and try again. The cover should go on with no extra force.
Once the filter is in place, secure the service cover.
