NORMAL
PROCEDURES
When using an external power source, the master switch must be in
the OFF position before connecting the external power source to the
l
airplane receptacle.
See Section 7, Ground Service Plug
Receptacle for external power source operations.
Cold weather starting procedures are the same as the normal
starting procedures. Use caution to prevent inadvertent forward
movement of the airplane during starting when parked on snow or
ice.
NOTE
If the engine does not start during the first few attempts, or if
engine firing diminishes in strength, it is probable that the
spark plugs have been frosted over. Preheat must be used
before another start is attempted.
During cold weather operations, no indication will be apparent on
the oil temperature gage 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
RPM. If the engine accelerates smoothly and the oil pressure re
mains normal and steady, the airplane is ready for takeoff.
WINTERIZATION KIT
A winterization kit is provided and may be utilized when cold weath
er operations are conducted.
