Air Cleaner Restriction Indicator
The air cleaner is equipped with a restriction indicator
(Figure 63). As the air cleaner element becomes clogged,
air intake restriction increases and the indicator signal
shows RED, indicating that the element needs to be
replaced. After replacing the air cleaner element, press the
restriction indicator button to reset the indicator.
