D DRAINING MOISTURE FROM FUEL SYSTEM (cont.)
(1) Drain each tank through its individual quick drain located at the lower inboard rear corner of the tank,
making sure that enough fuel has been drained to insure that all water and sediment is removed.
— 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.
(2) Place a container under the fuel selector valve drain. Depress the quick drain handle and allow a suffi-
cient amount of fuel to drain from the selector valve.
(3) Examine the contents of the container placed under the fuel selector valve drain for water and sedi-
ment and dispose of the contents.
— CAUTION —
When draining any amount of fuel, care should be taken to
insure that no fire hazard exists before starting engine.
E. DRAINING FUEL SYSTEM
Fuel may be drained from the system by opening the valve at the inboard end of each 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. Any individual tank may be drained by closing the selector valve and then
draining as desired.
F. ENGINE LUBRICATION
— 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 of four months, whichever occurs first. If a screen type filter is used, the screen
filter and oil should be changed every 25 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. The engine manufacturer does not recommended oils by brand names.
Use a quality brand Aviation Grade Oil of the proper season viscosity. For information on the use of deter-
gent oil, refer to recommendations for Changing Oil and/or the latest revision of Lycoming Service
Instruction No. 1014.
G. DRAINING OIL SUMP
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.POWER PLANT.
