WARNUNG
NOTICE
The engine design is for a conventional, non-aerobat-
ic, tractor or pusher configuration with the oil return
port in the optimum position. Assuming these points
are taken into consideration, the engine will be prop-
erly lubricated in all flight profiles. Aircraft that are not
conventional (e.g. airships, gyrocopters, dive brake
equipped aircraft, etc.) that require engine load at
steep inclination angles may have special lubrication
requirements.

NOTICE
Check that the connections for the oil feed and return
lines are correct.
