  Starting position: The automatic decompression operates for 

the manual starting of the engine with the crank handle. If the 

decompression unit's pin has moved to the operating position, 

the decompression has finished. The compression begins and 

the engine starts. 

  Neutral position: In the neutral position the compression is 

switched off. By turning the engine with the crank handle all 

bearings are provided with engine oil (e.g. following repair or 

before commencement of cold start at extremely cold 

temperatures). 

  Operating position: In the operating position the 

decompression is switched off and the engine is under 

compression.

NOTE! 

Never use the automatic decompression to 

switch off the engine.
