CESSNA SECTION 4
MODEL 152 NORMAL PROCEDURES
1 July 1978 4- 21
NOTE
Caution should be used to ensure the brakes are set or a qualified
person is at the controls.
6. Mixture RICH.
7. Throttle OPEN 1/2 to 3/4 INCH.
8. Prime -- 2 to 4 STROKES depending on temperature.
9. Primer -- RECHARGE for priming after engine start.
10. Propeller Area -- CLEAR.
11. Master Switch -- ON.
12. Ignition Switch -- START (release when engine starts).
13. Prime -- AS REQUIRED until the engine runs smoothly-
14. Throttle -- ADJUST for 1200 to 1500 RPM for approximately one minute after which the
RPM can be lowered to 1000 or less.
15. Oil Pressure -- CHECK.
16. Primer -- LOCK.
Without Preheat:
The procedure for starting without preheat is the same as with preheat except the engine
should be primed an additional three strokes just prior to pulling the propeller through by hand.
Carburetor heat should be applied after the engine starts. Leave the carburetor heat on until
the engine runs smoothly.
NOTE
If the engine fires but does not start or continue running, repeat the
above starting procedure beginning with step 6. If the engine does
not start during the first few attempts, or if engine firing diminishes
in strength, it is possible that the spark plugs have been frosted
over, in which case preheat must be used before another start is
attempted.
During cold weather operations, no indication will be apparent on the oil temperature gage
prior to takeoff if outside air temperatures are very cold. After a suitable warm-up period (2 to
5 minutes at 1000 RPM), accelerate the engine several times to higher engine RPM. If the
engine accelerates smoothly and oil pressure remains normal and steady, the airplane is ready
for takeoff.
