Service Instructions
Check the Restriction
Check the restriction level of the
air cleaner filter service indicator.
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
Remove the Vacuator Valve and clean
out any dust found in the drop tube.
Reinstall Vacuator Valve or replace if
found worn or damaged.
Gently Remove the Old
Filter
Shut off the engine. Loosen and
retain the wing nut bolt, remove bolt
and washer. Replace both if damaged
or worn.
Using the metal handle, pull the
dirty filter gently from the housing.
Accidental bumping will shake dirt
loose inside the filter housing.
Visually Check the Safety
Filter
Visually check the safety filter without
removing it. Replace if damaged or
every three primary filter changes.
Also verify that the safety filter is
properly seated in the housing.
If the safety filter is to be replaced,
it should be done immediately or the
clean air outlet should be sealed. Use
a clean cloth to avoid contaminant
being introduced to the engine during
service.

it looks like any of these images. A damaged or
