Above 12,000 ft the minimum manifold pressure is 15 in. Hg and the minimum
RPM is 2,000. Do not pull the throttle back to idle without leaning mixture appro-
priately above 12,000 ft. The lack of manifold pressure at altitude without leaning
will cause an over- rich condition. This condition may cause the engine to quit
above 18,000 ft. This condition may also cause the engine to quit when the
throttle is suddenly increased. If it does quit, it is possible to re- start the engine
at any altitude by leaning the mixture.
--CAUTION--
When changing power, the sequence control usage is important. Monitor the TIT
display to avoid exceeding 1750
F limit. To increase power, first increase the
mixture (not necessarily to FULL RICH), then increase RPM with the propeller
control and then increase manifold pressure with the throttle control. To de-
crease power, decrease manifold pressure first with the throttle control and then
decrease RPM with the propeller control. When engine temperatures have stabi-
lized, lean mixture to desired TIT.

OXYGEN SYSTEM
(OPTIONAL EQUIPMENT)
--WARNING--
Greasy lipsticks and waxed mustaches have been known to ignite spontaneously
inside oxygen masks. Passengers should be suitably advised prior to flight.
For safety reasons NO SMOKING should be allowed in the airplane while oxygen
is being used.
When ready to use the oxygen system, proceed as follows:
Mask and Hose

NOTE:
When the oxygen system is turned ON, oxygen will flow continuously at the ap-
propriate rate of flow for the altitude without any manual adjustments.
