
CAUTION: If oil pressure does not reach at
least 11.6 PSI within 10 seconds of
engine start, shut down the engine
immediately and determine the
cause.

CAUTION: If engine needs choke to idle
normally beyond an oil temperature
of 120°F, service may be required.
DO NOT attempt takeoff with choke
in ON position.
COLD WEATHER OPERATIONS
For engine start in temperatures below 32°F,
preheating is recommended. A warm air source
should be directed through the rear opening in the
lower cowling to warm the carburetor, intake
manifold, and engine oil sump.
Once the intake area is sufficiently warm, start
engine using the Cold Engine Start procedure. LET
ENGINE WARM ITSELF to normal operating oil
temperature and CHT with not more than 1200 rpm.
Installation and use of a Tanis® engine heater is
recommended for frequent operation in cold weather.
They are available through Arion Aircraft.
