7.2 Air Cleaner Restrictor Indicator
The air cleaner restriction gauge mounted on the air cleaner(s) helps determine the air cleaner change interval.
The air cleaner restriction gauge monitors air flow and continuously displays restriction readings indicated as vacuum
(see Figure 13). Increased restriction indicates a clogged air cleaner element.
As maximum allowable restriction is reached, the gauge window turns red indicating the air cleaner element needs replacement.
To reset the gauge, push the gauge top down and release.
