NOTICE

Always replace the secondary filter element. Never attempt to reuse it by cleaning.

The secondary filter element should be replaced at the time the primary element is serviced for the third time.

The secondary filter element should also be replaced if the yellow piston in the filter element indicator enters the red zone after installation of a clean primary element, or if the exhaust smoke is still black.



NOTICE

The filter should be kept in service for no longer than one year.



NOTICE

Always leave the secondary filter element in place while you clean the air cleaner housing.


Note: Replace the secondary filter element when you service the primary element for the third time. If a clean primary element has been installed and the engine air filter indicator still flashes, replace the secondary filter element. Also if the exhaust smoke remains black and a clean primary filter element has been installed, replace the secondary filter element.
