To test, turn the engine off. I f the yellow disc (Fig.
39) has reached the red colored zone on the gradu­
ated scale, . the air cleaner element should be
replaced. Refer to the proceeding removal/installation
paragraphs.
Resetting the F i l t e r Minder: After the air
cleaner (filter) element has been replaced, press the
rubber button on the top of the Filter Minder (Fig.
39). This will allow the yellow colored disc to reset.
After the button has been pressed, the yellow disc
should spring back to the UP position.
If the Filter Minder gauge has reached the red col­
ored zone, and after an examination of the air
cleaner (filter) element, the element appears to be
clean, the high reading may be due to a temporary
condition such as snow build-up at the air intake.
Temporary high restrictions may also occur i f the air
cleaner (filter) element has gotten wet such as during
a heavy rain or snow. I f this occurs, allow the ele­
ment to dry out during normal engine operation.
Reset the rubber button on the top of the Filter
Minder and retest after the element has dried.
