STARTING PROCEDURES
4.3.1
COLD ENGINES
The following starting procedures are recommended, however, the starting conditions may
necessitate some variation from these procedures.
1. Perform pre-flight inspection.
2. Set propeller governor control to "High RPM" position.
3. Open throttle approximately 1/4 travel.
4. Turn boost pump "ON".
5. Move mixture control to "FULL RICH" until a slight but steady fuel flow is noted (approximately
3 to 5 seconds) and return mixture control to "IDLE CUT-OFF". Turn boost pump "OFF".
6. Engage starter.
7. When engine fires release the ignition switch back to "BOTH".
8. Move mixture control slowly and smoothly to "FULL RICH".
9. Check the oil pressure gauge. If minimum oil pressure is not indicated within 30 seconds, shut
off the engine and determine cause of trouble.
4.3.2
HOT ENGINES
Because of the fact that the fuel percolates and the system must be cleared of vapor, it is
recommended to use the same procedure as outlined for cold engine start.
