evident, rectify and repair them before next flight.
Oil level
NOTICE
Operating media must be observed.
Inappropriate coolant quantity can lead to serious engine damage.
The specifications given in Chapter 2.4 must be adhered to
when refilling oil..
Step Procedure
1 Prior to oil level check, turn the propeller several times
by hand in direction of engine rotation to pump all the oil
from the engine to the oil tank.
2 This process is completed when air flows back to the oil
tank. This air flow can be perceived as a murmur (gur-
gling) when the oil tank cover of the oil tank is removed.
3 Pull out the oil dipstick.
4 The oil level in the oil tank should be between the two
marks (max./min.) on the oil dipstick, but must never fall
below the min. mark.
During standard engine operation, the oil level should be
mid-way between the max. and min. marks, as at higher
oil level (over servicing), oil will escape via the venting
passage
Difference between max.- and min.- mark = 0.60 litre
(1.268 liq pt).
5 Replenish oil as required.
6 Check oil level – Marks on the oil dipstick.
7 Fit the oil dipstick and tighten the oil tank cover by hand.
