CAUTION Do not over-prime or excessively pump the throttle (carburetor accelerator pump) due to the resulting fire hazard. The use of the fuel primer will vary with each engine and temperature condition. If the engine is warm, little or no prime is required. During cold weather conditions, 4 to 6 priming strokes may be required. - Page 9 12. Idle RPM 800 maximum 13. Controls free Take-Off - Normal 1. Controls - CHECK Free and Correct 2.

- Page 10 Full stall (3 point) landings are recommended for soft or rough fields. Crosswind approaches can best be accomplished by using the wing down, top rudder method followed by either a full stall or wheel landing technique. Keep the lower wing into the wind after touchdown. Do not drop the tail until airspeed is well below flying speed.
