NORMAL PROCEDURES
4.4.2
STARTING ENGINE
If the engine is warm, no choke is required. For the first start of the day and
in cold conditions, applying choke will be necessary.
If the airplane will be started using external power, keep all personnel and
power unit cables well clear of the propeller rotation plane.

CAUTION:
After starting, if the oil gauge 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 indi-
cates loss of lubrication, which can cause severe engine damage. In this time
also consider the time the avionics suite needs to start displaying engine
information.
