Any good automotive wax may be used to preserve the painted surfaces. Soft cleaning cloths or a chamois should be used to prevent scratches when cleaning or polishing. A heavier coating of wax on the leading surfaces will reduce the abrasion problems in these areas.

FILLING FUEL TANKS.
The fuel tank of each wing is filled through a single filler located on top of the nacelle.  Each tank has a capacity of 55 U.S. gallons, giving a total capacity of 110 U.S. gallons.
1.
Observe all required safety precautions for handling gasoline.

2.
Fill the tanks with fuel as specified on the placard adjacent to the filler neck.

DRAINING MOISTURE FROM FUEL SYSTEM.
To facilitate draining the fuel system fuel filters, lines and tanks of moisture and foreign matter, drains are incorporated in the starbord fuselage at a point just aft of the right flap trailing edge.
DRAINING FUEL SYSTEM.
The bulk of the fuel may be drained by opening the valves at the right hand side of the fuselage just forward of the entrance step or by siphoning (when draining fuel through the drain valves, the selector valves should be "ON"). The remaining fuel in the lines may be drained through the fuel filters.
