NOTE: Do not use compressed air if there is oil or soot in
the element.
If the cartridge is greasy:
Clean it in water, with suitable detergent. (Consult your
CASE CONSTRUCTION dealer).
Instructions for using the detergent are printed on the
package.
NOTE: Dry the element out completely before installing it.
It is advisable to keep a clean spare element ready that can
be installed on the air cleaner while the cleaned element is
drying.
Inspecting the element
Check the element for damage by placing an inspection
lamp inside the element.
NOTE: Change the element if light can be seen through a
hole, however small.
5. Clean the inside of the air cleaner case, and attach the
primary element.
6. Attach the cover (with the "TOP" display facing up), and
lock the fasteners.
NOTICE: The mass air flow (MAF) sensor is mounted on the inlet duct of the air cleaner. Output of the engine may
be restricted if any dust is attached to the MAF sensor or failure of sensing part of the MAF sensor due to usage of
retailed cleaning fluid.
Pay attention not to allow dust to invade the inlet duct when replacing the air cleaner element. Also, pay attention not
to spray retailed cleaning fluids to the MAF sensor when using them.
