Oil level (oil dip-
stick)
NOTE: The oil level should be in the upper half (be-
tween the “50%“ and the “max“ mark) and
should never fall below the “min“ mark. Prior to
long flights oil should be added so that the oil
level reaches the “max“ mark.
Avoid oil levels exceeding the “max“ mark, since excess oil could
be poured out through the venting system.
Difference between max.- and min.- mark = 0.45 litre (0.95 liq pt)
The oil specifications of the section Chapter
2.4)
Operating media are to be observed!
Step Procedure
1 Check oil level and replenish as required.

NOTE: Propeller shouldn't be turned exces-
sively reverse the normal direction of
engine rotation.
Remove oil tank cap. Prior to oil check, turn the propeller
by hand in direction of engine rotation several times to
pump oil from the engine into the oil tank.
3 It is essential to build up compression in the combustion
chamber. Maintain the pressure for a few seconds to let the
pressure flow around the piston rings into the crankcase.
The speed of rotation is not important for the pressure
transfer into the crankcase.
4 This process is finished when air is returning back to the oil
tank and can be noticed by a murmur from the open oil
tank.
5 Install oil tank cap.
