5.2.2 Warm Engine
As for cold start, with the following differences:
Choke
OFF
Throttle
Slightly “Cracked” from off position (approx 2%).
5.3
Warming Up Period
Start the warming up period with the engine running at 1200 RPM for around 1 minute.
Continue at 2000 RPM depending on ambient temperature, until oil temperature reaches 15°C
(59°F).
Check the two ignition circuits at 2000 RPM
Note: Engine RPM should not drop by more than 100 RPM when 1 ignition is turned OFF.
WARNING
DO NOT apply full power until CHT reaches 100
°
C (212

F)
DO NOT apply full power until Oil Temperature reaches 40

DO NOT allow cylinder heads to rise above 180
°
C (356
°
F) during ground running.
5.4
Ground Running
When running the engine on the ground before flight use minimum power settings and
minimum time to avoid overheating: the engine is already run-in and further ground running can
be detrimental.
Avoid prolonged ground running at elevated RPM as the engine can easily be over heated
during ground operations
– remember air ducts are designed for
in flight
cooling.
Ground running at high power settings for more than a few minutes requires the use of special,
oversize air ducts and oil cooler.
WARNING
Prolonged running at full power on the ground can cause engine overheating & damage
unless special, oversized air ducts and oil coolers are used.
5.5
Take-Off
Ensure all temperatures and pressures are within limitations before applying take-off power.
Climb with the engine at maximum continuous power.
Observe Oil & Cylinder Head Temperatures & Oil Pressure.
Max RPM at Full Throttle is 3300 RPM
WARNING
Limits must not be exceeded!
5.6
Engine Stop
In normal conditions the engine will cool enough during descent & taxiing to permit it to be
stopped by switching OFF the ignitions.
