11) Checks
All checks to be carried out as specified in the current Maintenance Manual (last

on this particular engine, are allowed to carry out maintenance

11.1) Engine preservation
If the engine is not going to be used for a extended period of time, certain
measures must be taken to protect engine against heat, direct sun light,
corrosion and formation of residues.
In particular the water bonded by the alcohol in the fuel causes increased
corrosion problems at engine stops or storage. Especially affected are
essential engine components such as crankshaft bearings and conrod bear-
ings as well as crank pins and piston pins.
11.1.1) After each flight
– Activate choke for a moment before stopping engine
– Close all engine openings like exhaust pipe, venting tube and
air filter to prevent entry of contamination and humidity.
11.1.2) At engine stoppage of 1 to 4 weeks
– proceed with preservation prior to engine stop or on the engine
at operating temperature.
– let the engine run at increased idle speed
– shut engine down and secure against inadvertent engine start
– remove air filters and inject approx. 3 ccm of preservation oil
or equivalent oil into the air intake of each carburetor.
– restart engine and run at increased idle speed for 10 - 15
seconds
– shut engine down and secure against inadvertent engine start
– close all engine openings such as exhaust pipe, venting tube
and air filter to prevent entry of contamination and humidity.
