How to check the air cleaner restriction indicator

1 The middle section of the restriction indicator will remain clear while the air cleaner is in a serviceable
condition.
2 When the filter reaches its contamination limit the restriction indicator will sense the change in manifold
pressure and middle section (A1) will change to red. At this point the air filter must be changed.
3 When the air filters have been changed reset the indicator by pressing button (A2).
