HANDLING AND SERVICING
To refuel airplane:
1 Place fire extinguisher near fuel tank being filled.
2
Connect ground wire from refuel nozzle to airplane exhaust, from
airplane exhaust to fuel truck or cart, and from fuel truck or cart to a
suitable earth ground.
3 Place rubber protective cover over the fuselage around fuel filler.
4 Remove fuel filler cap and fuel airplane to desired level.
NOTE: Keep fuel tank at least half full at all times to minimize condensation
and moisture accumulation in the tank. In extremely humid areas, the fuel
supply should be checked frequently and drained of condensation to pre-
vent possible distribution problems.
5 Remove nozzle, install filler cap, and remove protective cover.
6 Remove ground wires.
7 Remove fire extinguisher.
Fuel Draining and Sampling
Typically, fuel contamination results from foreign material such as water, dirt,
rust, and fungal or bacterial growth. Additionally, chemicals and additives
that are incompatible with fuel or fuel system components are also a source
of fuel contamination. To assure that the proper grade of fuel is used and
that contamination is not present, the fuel must be sampled prior to each
flight.
Fuel drains is provided for the fuel gascolator. Fuel must be sampled by
draining a cupful of fuel into a clear sample cup.
The gascolator drain is accessible through the lower engine cowling (left
side) just forward of the firewall.
If sampling reveals contamination, the gascolator must be sampled again
repeatedly until all contamination is removed. If after repeated samplings,
evidence of significant contamination remains, do not fly the airplane until
a mechanic is consulted, the fuel system is drained and purged, and the
source of contamination is determined and corrected.
The gascolator sampling outlet is open by rotating the knob and closed by
