CAUTION: WHEN DRAINING ANY AMOUNT OF FUEL, INSURE THAT NO FIRE HAZARD
EXISTS BEFORE STARTING ENGINE.
To drain the fuel system, open valve at inboard end of each fuel tank. Push up on drain valve arms
and turn counterclockwise to hold drain in the open position. The flush type drain valve requires
drain cup pin to hold valve open. Drain remaining fuel through filter bowl. Any individual tank is
drained by closing selector valve and then draining.
2. Oil System
CAUTION: DO NOT INTRODUCE ANY TRADE ADDITIVE TO THE BASIC LUBRICANT UNLESS
RECOMMENDED BY THE ENGINE MANUFACTURER.
Engine oil level should be checked before each flight. The engine oil and full flow cartridge filter should
be changed every 50 hours or four months, whichever occurs first. Refer to the latest revision of
Lycoming Service Bulletin No. 480. Should fuel other than the specified octane rating for the power plant
be used, refer to the latest revision of Lycoming Service Letter No. L185 for additional information and
recommended service procedures. Use a quality brand Aviation Grade Oil of the proper season
viscosity. For information on the use of detergent oil, refer to Recommendations for Changing Oil, below,
and/or the latest revision of Lycoming Service Instruction No. 1014.

A. Oil Sump
(1) Draining
NO
TE: Warm the engine to operating temperature to insure complete draining of the old oil.
To drain the oil sump, provide a suitable container with a minimum capacity of that required to
fill the sump. Remove the engine cowl and open the oil drain located on the underside of the
engine by pushing the arms of the drain up and turning counterclockwise. This will hold the
drain in the open position.
(2) Filling
The oil sump should normally be filled with oil to the mark on the engine dipstick. The quantity
of oil required for the engine may be found in 6-00-00, Chart 1. The specified grade of oil may
be found in the Lubrication Chart, 12-20-00; on the inside surface of the engine oil filler access
door; or in the latest revision of Lycoming Service Instruction No. 1014. To service the engine
with oil, open the quick release oil filler access door on top of the cowl, and remove the oil filler
cap with dipstick.
(3) Oil Screen (Suction)
The oil suction screen, located on the bottom aft end of the engine sump, is installed
horizontally. To remove, cut the safety wire and remove the hex head plug. The screen should
be cleaned at each oil change to remove any accumulation of sludge and to examine for metal
filings or chips. If metal particles are found in the screen, the engine should be examined for
internal damage. To avoid possible damage to the screen, after cleaning and inspection, place
the screen inside the recess in the hex head plug and insert the screen into the housing. When
certain that the screen is seated properly, tighten and safety the plug with MS-20995-C41
safety wire.
