8.1) Engine preservation
General note
Due to the special material of the cylinder wall, there is no need
for extra protection against corrosion for the ROTAX aircraft engi-
nes. At extreme climatic conditions and for long out of service pe-
riods we recommend the following to protect the valve guides
against corrosion:
8.2) Engine back to operation
If preservation including oil change took place within a year of sto-
rage, oil renewal will not be necessary. For longer storage periods
repeat preservation annually.
Risk of burnings and scalds!
Hot engine parts!
Always allow engine to cool down to ambient
temperature before start of any work.
Step Procedure

gine rotation, so that the corrosion inhibiting oil all necessary
points reaches.
6 Install the Spark plug in according the Maintenance Manual.
7Close all openings on the cold engine, such as exhaust end
pipe, venting tube, air filter etc. against entry of dirt and hu-
midity.
