NEW YORK AIRWAYS

6.3.4 STARTING ENGINE Continued

12. Mixture lever -- Rich (after engine starts).

NOTE: Should the engine fail to start within 30 seconds, let the starter cool for two minutes, then repeat the starting procedure.

13. Engine oil pressure and temperature gages -- Check. (Stop engine if the oil pressure does not register within 10 seconds or reach 40 psi within 20 seconds after starting).
14. Throttle -- 1100-1200 engine rpm.

CAUTION: Care should be exercised when operating throttle as it is extremely  sensitive when clutch is disengaged. Improper operation could result in excessive engine speed.

15. Manifold pressure purge button -- Press.
16. Inverter switch -- Check spare and off positions, then switch to main.
17. Fuel quantity test switch -- On as required for test.
18. Carburetor heat lever -- Hot, then cold. Check for rise in carburetor air temperature when in hot position.

6.3.5 AFTER ENGINE STARTS -- Warm-Up 

1. Throttle -- 1700 engine rpm. (This speed will provide smoothest operation of engine while lubricating oil is cold). 

Ignition Switch Check
After engine warm-up and prior to engaging rotors check the ignition switch for proper connection of ground wire.
1. Ignition switch -- Both..
2. Throttle -- Closed ( index marks opposite one another ).
3. Ignition switch -- Off == momentarily. (Observe that engine stops firing).
4. Ignition switch -- Both.

CAUTION: Make this check as quickly as possible to prevent engine backfire. If violent backfiring occurs during ground run of engine, a shutdown must be made to inspect the engine, induction, and accessory system for damage.

Fuel Pump Check -- Engine and Booster
1. Fuel booster pump switch -- Off.
2. Fuel pressure gage --  observe fuel pressure reading within limits and warning light.
3. Fuel booster pump switch -- On.

6.3.6] ENGAGING ROTORS

CAUTION: Rotor engagement must not be attempted when the clutch warning light is on. Under this condition, the clutch will travel immediately into the jaw position instead of starting friction engagement; and damage to the rotor system from premature jaw clutch engagement will result.
