After Starting; Taxiing - Beechcraft Baron G58 Pilot Operating Handbook

Model G58
Under very cold conditions, it may be necessary to preheat the
engines prior to a start. Particular attention should be given to
the oil cooler, engine sump and propeller hub to ensure proper
preheat. A start with congealed oil in the system may produce
an indication of normal pressure immediately after the start,
but then the oil pressure may decrease when residual oil in the
engine is pumped back with the congealed oil in the sump. If
an engine heater capable of heating both the engine sump and
cooler is not available, the oil should be drained while the
engine is hot and stored in a warm area until the next flight.

AFTER STARTING

If there is no oil pressure within the first 30 seconds after start,
or if oil pressure drops after a few minutes of ground operation
shut down and check for broken oil lines, oil cooler leaks, or
congealed oil.
It is advisable to use external power for
starting in cold weather.
During warm-up, monitor engine temperature closely since it is
quite possible to exceed the cylinder head temperature limit in
trying to increase the oil temperature. Exercise the propeller
several times to remove cold oil from the pitch change mecha-
nism. The propellers should also be cycled occasionally in
flight.

TAXIING

Avoid taxiing through water, slush or muddy surfaces if possi-
ble. In cold weather, water, slush or mud splashed onto land-
ing gear mechanisms or control surface hinges may freeze,
preventing free movement and resulting in structural damage.
