How to change the air filter
Warning! Discard the used element in a safe place and in accordance with local regulations.
Cautions:
! Do not operate the engine if there is a blockage in the air filter or the induction hose.
! The air filter element is a non-serviceable item, do not clean the element.
! Never blow dirt out of the filter housing. This may introduce dirt into the induction system. The housing must
be removed to be cleaned.
Note: Environmental conditions have an important effect on the frequency at which the air filters need to be
serviced.
How to check the air restriction indicator
Note: The middle section of the restriction indicator (A1) will remain clear while the air cleaner is in a
serviceable condition. When the filter reaches its contamination limit the restriction indicator will sense the
change in manifold pressure and middle section (A3) will change to red. At this point the air filter must be
changed.
When the air filters have been changed in order to reset the indicators operate the button (A2).
