The items noted below must be checked in addition to those listed previously.
1. Instrument lights -- Check.
2. Navigation lights -- Check.
3. Landing light -- Check
4. Anti-Collision lights -- Check.

NOTE: If possible, checks should be made with the aid of ground  crew and with electrical power connected or after the engine is operating.

5. Personal equipment -- Check for stowage, required equipment.

1. Generator warning light -- On
2. Warning lights -- Press to test.
3. Fire warning test button -- Press to test system (15 seconds maximum).
4. Friction  clutch switch -- Disengaged.

CAUTION: It is possible to engage the starter with either the friction or jaw clutch engaged causing damage to the rotor system, if the master and ignition switches are ON and the engine starts.

5. Fuel booster pump switch -- On (pressure within limits).
6. Fire guard -- Alerted.
7. No smoking sign -- On.
8. Fasten seat belt sign -- On.
9. Starter button -- Press to engage. (With fuel booster pump OFF, check for liquid lock and then turn the fuel booster pump ON).

CAUTION: The presence of liquid in a combustion chamber will cause serious damage if a start is made. Therefore, the engine must be cleared before starting is attempted. To clear the engine, press the starter which (not exceeding four to five seconds) to assure that the engine turns freely. If hydraulic lock is present, the low torque starter clutch will slip and the engine will not turn over. If this occurs, or, if the engine seems to turn through with difficulty release the starter button and have the spark plugs removed from the lower cylinders, and drain all liquids by cranking the engine through a minimum of two revolutions.

To prevent engine overspeeds on starting, apply sufficient throttle friction before starting to prevent throttle from moving if released.

10. Ignition switch -- Both.
11. Primer switch -- As required.

CAUTION: Do not use primer switch until engine has turned over for approximately three seconds to forestall hydraulic lock in the lower cylinders.
