CAUTION: AFTER EACH USE OF THE QUICK DRAIN VALVE, CHECK THE FUEL
SELECTOR VALVE DRAIN TO ENSURE THAT THE QUICK DRAIN VALVE
HAS PROPERLY SEATED AND THAT THERE IS NO LOSS OF FUEL
FROM THE DRAIN.
(b) Place a container under the fuel selector valve drain. Depress the quick drain handle and
allow a sufficient amount of fuel to drain from the strainer.
NOTE
: The fuel selector should be positioned in the following sequence while draining
the strainer: “OFF,” “LEFT” and “RIGHT.” This is done to insure that the fuel in the
lines between each tank outlet and the fuel strainer is drained, as well as the fuel
in the fuel strainer. When the fuel tanks are full, it will take approximately six
seconds to drain all the fuel in one of the lines from a tank to the fuel strainer. If
the fuel tanks are less than full, it will take a few seconds longer.
(c) Examine the contents of the container placed under the fuel selector valve drain for water
and sediment and dispose of the contents.
(3) Draining Entirely
CA
UTION: WHEN DRAINING ANY AMOUNT OF FUEL, INSURE THAT NO FIRE HAZARD
EXISTS BEFORE STARTING ENGINE.
Fuel may be drained from the system by opening the valve at the inboard end of each
aluminum fuel tank. The flush type drain valve requires the drain cup pin to hold the valve
open. The remaining fuel in the system may be drained through the filter bowl. Either wing may
be drained by closing the selector valve and then draining as desired.
C. Flushing Tanks and Selector Valve
(1) To flush the fuel tanks and selector valve, disconnect the fuel line at the injector.
(2) Select a fuel tank, turn on the electric fuel pump and flush fuel through the system until it is
determined there is no dirt and foreign matter in the fuel valve or tank. During this operation,
agitation of the fuel within the tank will help pick up and remove any dirt.
(3) Repeat this procedure for each tank.
(4) When all tanks are flushed, clean all filters.
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 480. Should fuel other than the specified octane rating for the power plant be
used, refer to the latest revision 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 and/or
the latest revision of Lycoming Service Instruction No. 1014.
A. Oil Sump
(1) Draining
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. It is recommended the engine be warmed to operating temperature
to insure complete draining of the old oil.
