This servicing information is provided as a best practices guide. It is not intended to replace or supersede the
service instructions supplied by your engine or vehicle manufacturer.
Check the Restriction
Replace the filter only when the restriction level
has reached the maximum recommended by
the engine or equipment manufacturer or on a
regular service schedule.
Clean out the Vacuator
™
Valve
If your air cleaner is equipped with a Vacuator
™
Valve, visually check and physically squeeze it.
Make sure the valve is flexible and not inverted,
damaged or plugged.
Remove the Primary filter
Shut off the engine. Unfasten or unlatch the
service cover. For the FPG Alexin
™
models, the
cover is unlocked with a yellow “finger”, twisted
to the left and removed from the filter housing.
The RadialSeal
™
filter fits tightly over the outlet
tube and there will be some initial resistance,
similar to breaking the seal on a jar. Gently move
the end of the filter back and forth to break the
seal, then rotate while pulling straight out. Avoid
knocking the filter against the housing.
Visually Check the Safety Filter
and Clean Both Surfaces of the
outlet tube
If your air cleaner has a safety filter, visually
check it while in place for signs of damage. Do
not remove the safety filter unless it is damaged
or due for replacement. Also verify that the
safety filter is properly seated in the housing.
The safety filter should be replaced every three
primary filter changes. Use a clean damp cloth
to wipe both the filter sealing surface and the
inside of the outlet tube. Ensure that the outlet
tube sealing area is undamaged.
Contaminant on the sealing surface could hinder
an effective seal and cause leakage. If the safety
filter is to be replaced, avoid leaving the outlet
tube exposed to the air. If there is to be a delay
in installing the new safety filter, cover the air
cleaner outlet tube to avoid admitting any dust.
