6.3. Preservation of the engine for long term storage 
For long out of operation periods and at extreme climatic conditions, we 
recommend the following instructions to protect against corrosion. Extra 
protection against corrosion beyond these recommendations is not necessary. 

1.  Warm up the engine, stop the engine, and empty the motor oil. 
2.  Fill up with new oil. 
3.  Drain the float chamber of the carburetors. 
4.  Apply oil to all pivots on the carburetors. 
5.  Close all openings, the exhaust tubes, the breather tube and air filters. 

Protect them against dirt and moisture. 

6.  Coat all the steel engine parts with engine oil. 

 
Bringing the engine back to operation 

1.  Remove all the plugs and fasteners. 

 

 

 

CAUTION!

 

 For longer storage periods, the preservation procedures must be

performed at least annually. 

 
6.4. Winter operation 
6.4.1. Care of the electrical system 
Generally in the beginning of the winter an engine inspection shall be 
performed. 

  Check all the connections of the ignition system and clean if necessary. 

  Check the battery voltage. 

  The battery poles and terminal connectors should be cleaned. 

In countries with extremely low temperatures it is recommended to protect the 
battery against freezing by keeping it in a warm location for storage between 
flights. (See Sec 3.6)
