(I) Remove the lower cowl.
(2) Remove the wing nuts securing the filter. Remove the filter.
(b) Cleaning Engine Air Filter
The induction air filter must be cleaned at least once every 50 hours, and more often, even
daily, when operating in dusty conditions. Extra filters are inexpensive, and a spare should be
kept on hand for use as a rapid replacement.
To clean the filter:
(I) Tap the filter gently to remove dirt particles, being careful not to damage the filter. DO
NOT wash the filter in any liquid. DO NOT attempt to blowout dirt with compressed
air.
(2) If the filter is excessively dirty or shows any damage, replace it immediately.
(3) Wipe the filter housing with a clean cloth and install the filter. The usable life of the
filter should be restricted to one year or 500 hours, whichever comes fITS!.
(c) Installation Of Engine Air Filter
After cleaning or when replacing the filter, install the filter in the reverse order of removal.
8.13 BRAKE SERVICE
The brake system is filled with MIL-H-5606 (petroleum base) hydraulic brake fluid. The fluid level
should be checked periodically or at every 50 hour inspection and replenished when necessary. The brake
reservoir is located on the nre wall in the engine compartment. If the entire system must be refilled, fill
with fluid under pressure from the brake end of the system. This will eliminate air from the system.
No adjustment of the brake clearances is necessary. If after extended service brake blocks become
excessively worn, they should be replaced with new segments. .
