COLD WEATHER OPERATIONS
If external power is not available, do not attempt the self
warming procedure. The battery will likely become depleted
below the minimum voltage necessary for engine start.
External warm-air preheat may be applied to the cabin area. Use
caution as excessively hot preheated air may damage interior or
instrumentation. Due to fuel lines routed through cabin area, gas fired
or exposed flame heaters should not be used to warm the cabin area.

STARTING

When air temperatures are below 20°F (-6°C), use an external
preheater and an external power source, if external power receptacle is
installed, whenever possible to obtain positive starting and to reduce
wear and abuse to both the engine and electrical system. Preheat will
thaw the oil trapped in the oil cooler, which probably will be congealed
prior to starting in extremely cold temperatures.
WHEN TURNING THE PROPELLER BY HAND, TREAT IT
AS IF THE MAGNETOS SWITCH IS IN THE ON
POSITION. A LOOSE OR BROKEN GROUND WIRE ON
EITHER MAGNETO COULD ENERGIZE THE ENGINE.
Prior to starting on cold mornings, it is advisable to turn the propeller
manually through several engine compression cycles by hand to loosen
the oil, so the engine cranks (motors) more easily and uses less battery
power. When the propeller is turned manually, turn it in the opposite
direction to normal engine rotation for greater safety. Opposite rotation
disengages the magneto impulse couplings and prevents possible
unwanted ignition.
When using an external power source, the MASTER Switch (ALT and
BAT) sections must be in the OFF position before connecting the
external power source to the external power receptacle. Refer to
Section 7, Starting Engine with External Power, for system description
and operations.
