Starting Engine
If the engine is warm, no priming is required. For the first start of the
day and in cold conditions, prime will be necessary.
Weak intermittent firing followed by puffs of black smoke from the
exhaust stack indicates over-priming or flooding. Excess fuel can be
cleared from the combustion chambers by the following procedure:
• Turn fuel pump off.
• Allow fuel to drain from intake tubes.
• Set the mixture control full lean and the power lever full open.
• Crank the engine through several revolutions with the starter.
• When engine starts, release ignition switch, retard power lever,
and slowly advance the mixture control to FULL RICH position.
If the engine is under-primed, especially with a cold soaked engine, it
will not fire, and additional priming will be necessary. As soon as the
cylinders begin to fire, open the power lever slightly to keep it running.
Refer to Cold Weather Operation in this section or additional
information regarding cold weather operations.
• WARNING •
If airplane will be started using external power, keep all
personnel and power unit cables well clear of the propeller
rotation plane.
• Caution •
Alternators should be left OFF during engine starting to avoid
high electrical loads.
After starting, if the oil gage does not begin to show pressure
within 30 seconds in warm weather and about 60 seconds in
very cold weather, shut down engine and investigate cause.
Lack of oil pressure indicates loss of lubrication, which can
cause severe engine damage.
1. External Power (If applicable) ....................................... CONNECT
2. Brakes ..................................................................................HOLD
3. Bat Master Switches ........................................... ON (Check Volts)
