(c) Draining Fuel System
The bulk of the fuel may be drained from the system by opening
the valve at the inboard end of each tank. Push up on the arms of the
drain valve and turn counterclockwise to hold the drain open. Drain
the fuel from the fuel strainer bowl and remove the fuel supply line
at the carburetor servo. Run the electric driven fuel pump until the
system is completely drained, this will require selecting all fuel tanks
to ensure fuel is drained from all lines.
CAUTION
When the fuel system is completely drained and
fuel is replenished it will be necessary to run the
engine for a minimum of 3 minutes at 1000
RPM on each tank to ensure no air exists in the
fuel supply lines.
8.23 TIRE INFLATION
For maximum service from tires, keep all three inflated to the proper
pressure, 26 psi for the standard 5.00 x 5 tires and 30 psi for the optional
6.00 x 6 tires*. All wheels and tires are balanced before original installation,
and the relationship of tire, tube and wheel should be maintained upon
reinstallation. Unbalanced wheels can cause extreme vibration in the
landing gear; therefore, in the installation of new components, it may be
necessary to rebalance the wheels with the tires mounted. When checking
tire pressure, examine the tires for wear, cuts, bruises, and slippage.
CAUTION
Proper tire inflation must be maintained to pre-
vent high sensitivity of the nose wheel steering
during takeoff and landing.
8.25 BATTERY SERVICE
Access to the 12-volt battery is obtained by raising the right side of the
top cowl and removing the cover of the battery box. The battery box has
* 6.00 x 6 wheel assemblies are standard on aircraft with serial nos.
