COLD WEATHER OPERATION
(Continued)
STARTING
(Continued)
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 airplane receptacle. Refer to Section 7,
External Power Receptacle, for external power source operations.
Cold weather starting procedures are the same as the normal starting
procedures. However, to conserve battery power the beacon light can
be left off until the engine is started. Use caution to prevent inadvertent
forward movement of the airplane during starting when parked on snow
or ice.
During cold weather starting, when performing the Standby Battery
energy level test, the test lamp may not illuminate and the BUS E volts
may be less than 24 volts before turning on the MASTER (ALT and
BAT) switch. After engine start, verify the S BATT ammeter shows a
charge (positive) at 1000 RPM or greater. Prior to takeoff verify the S
BATT ammeter shows a charge less than 0.4 amps.
NOTE
If the engine does not start during the first few attempts, or
if engine firing diminishes in strength, the spark plugs may
be frosted over. Preheat must be used before another start
is attempted.
During cold weather operations, the oil temperature indicator may not
be in the green band prior to takeoff if outside air temperatures are very
cold. After a suitable warm up period (2 to 5 minutes at 1000 RPM),
accelerate the engine several times to higher engine RPMs. If the
engine accelerates smoothly and the oil pressure remains normal and
steady, the airplane is ready for takeoff.
