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 low
temperatures).
Operating position: In the operating position the
decompression is switched off and the engine is under
compression.
