The air filter should not be changed until the indicator
reads RED. Dispose of the old air filter. It may not be
cleaned or reused.
The air filter indicator (Figure 66) is attached to the air
filter. When the air filter element is clogged, air intake
restriction becomes greater and the air filter indicator signal
shows RED. When the indicator is red, replace the filter
immediately. After changing the air filter, press the air filter
indicator button to reset.

filter body.
2. To discharge the fuel inside the fuel filter, OPEN
the drain valve on the fuel filter by turning the knob
counterclockwise (Figure 67A) approximately
3-1/2 turns until the valve drops down 1 inch (25.4 mm)
and draining occurs (Figure 67B).
