3. Operation
The engine is run-in at the factory for 2 hours and requires no further ”breaking in” after
installation. All relevant items were adjusted for optimum performance and the carburetor is
set to operate satisfactorily between sea level and 2000 meters MSL (6,514 ft MSL) without
requiring different jetting or further adjustment. (See note below) Nevertheless, all gauges
should be monitored with extra attention during the first few hours of service, with
particular attention to the temperature and pressure limitations shown below:
Engine speed:
Maximum speed: 7800 RPM, for 3 minutes maximum
Operating speed: 5500 - 6000 RPM
It is recommended to maintain operating speed within the range of 5500 - 6500 RPM, where
power, fuel consumption and engine wear are in ideal configuration.
Water temperature:
Maximum temp : 100 °C (212 deg F) - For 5 minutes maximum!
Operating temp : 75 - 85 deg C (170 - 192 deg F)
Minimum temp : 60 deg C (136 deg F)
It is forbidden to exceed operating temperature 85°C during engine operation. The
maximum temperature 100°C can be used only in the state of emergency and for 5 minutes
maximum! Head deflection and other accompanying defects can occur when exceeding ope-
rating temperature.
The minimum operating temperature 60°C is measured during level horizontal flight and en-
gine operation under lower temperature is forbidden.
Exhaust gas temperature:
Operating temp: 620 - 820 deg.C (1150 - 1300 deg.F)
Note:
For reference only: EGT gauge is not a mandatory requirement for this engine.
Oil temperature and pressure:
Oil pressure: 0.3 - 4.0 kg/cm2 (4.35 - 58 psi)
Oil temperature: 50 - 85 °C, (122 - 185 deg F), 100° C (212 deg F) for short time only!
Note:
The oil temperature must reach the minimum temperature shown above before the
carburetor throttle is wide open and it is the lowest temperature suitable for engine
operation. The highest possible oil temperature during engine operation is 90°C and only in
the state of emergency can it be exceeded up to 100°C for a short time.
Carburetor throttle must be reduced to minimum flight worthy revolutions and landing
made at the nearest landing place if any of above mentioned values get near or reach
maximal mentioned limits. Cause of the problem must to be identified and fixed before next
flight.
