Step
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.
This process is completed when air flows back to the oil tank. This air flow
can be perceived as a murmur (gurgling) when the oil tank cover (1) of the
oil tank is removed.
Pull out the oil dipstick (2).
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. See Service Bulletin
SB-912-040, "Introduction of a new oil dipstick", latest issue.
NOTICE
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 see also SI-27-1997, "oil level check", latest issue.
Difference between "max." and "min". - mark = 0,45 l (0.95 liq.pt)
Replenish oil as required.
NOTICE
Procedure
For longer flights replenish oil to max. mark to warrant more
oil reserve.
Only use brand name oil in accordance with the latest Op-
erators Manual and SI-912-016, "Selection of suitable op-
erating fluids" latest issue.
