The dry type induction air filter must be inspected and cleaned at least
once every 50 hours, and more often, even daily, when operating in dusty
conditions. The filter is disposable and inexpensive and a spare should
always be kept on hand for a rapid replacement.

The filter is located in the lower front of the engine compart-
ment and is accessible through the chin scoop intake with the
cowling intact. It may be removed by the following procedure:
(l) Loosen the 1/4-turn attachment screws securing the filter.
The top screws are accessible through the intake opening,
the bottom screws through the two ports on the underside
of the scoop.
(2) Remove the filter through the intake opening.
(b) Cleaning Engine Air Filter
(1) Tap the filter gently to remove loose dirt particles, being
careful not to damage the filter. DO NOT wash the filter in
any liquid. DO NOT attempt to blow out dirt with
compressed air.
(2) If the filter is excessively dirty or shows any damage,
discard it and replace it immediately.
(3) Wipe the filter housing with a clean cloth.
(c) Installation of Engine Air Filter
After cleaning or when replacing the filter, install the filter in
the reverse order of removal.
