The decompression valve is part of the easy start-system. The valve should be pressed before starting to cut the compression pressure when starting, as well as the effort needed to pull the starter rope. The decompression valve is semi-automatic, meaning that it must be pressed manually before starting, but then closes automatically.
All important functions such as start, choke, throttle and stop are operated via a single lever.
