As soon as the engine is running smooth , deactivate the choke.
Push the choke lever forward gradually and not suddenly.
17. Warm up the engine.
If the engine has been started at a cold temperature , then keep the
rpm between 2000 to 2200 and allow the engine to warm up for 1
to 2 minutes to achieve a smooth run.
Then, the rpm can be increased to 2500 in order to achieve the
minimum oil temperature of 50 degrees Celsius. During the engine
warm up, the cylinder head temperature (CHT) will start to rise
before the oil pressure does. Once the oil pressure reaches 50
degrees Celsius, then the static run-up test for the aircraft can be
conducted by selecting the right and left ignitions individually.
18. Static Run-up test.
The minimum oil temperature for this is 50 degrees Celsius.
Do not carry out the static run-up test with the aircraft on a rough
surface ( e.g. small stones or sand). The propeller rotation creates
a suction below it, which can lift contamination into the prop. This
can cause damage to the blades. In light wind conditions, the
aircraft does not need to be pointed into the wind, however if wind
speeds are above 3 m/s ( 6 knots), the aircraft should be pointed
into the wind during the static run-up.
Increase the engine rpm to 4000 by turning the throttle clockwise,
then check both ignitions individually by the following procedure.
Note that the rpm is at 4000 with both ignitions on. Then switch the
ignition key to the right position, and note the rpm (The maximum
allowable drop in rpm is 300, e.g. the rpm can not fall below 3700 ).
Then return the ignition key to the BOTH position, and note again
that the rpm is at 4000. Then switch the ignition key to the left
position and note the rpm (The maximum allowable drop is 300 e.g.
the rpm can not fall below 3700 ). The rpm that was observed while
running on the right position and the rpm that was observed while
running on the left position should be compared. The difference
between these two rpm settings can not differ by more that 120
rpm.
