Sorry, can't help. I have seen a picture of that setworks some where in my literature collection. One lever must be for fast recede.

In a brochure from the fifty's I found the 3 handle set works.  They called it double action with power recede. This did not have a reach rod for the sawyer but was operated by the carriage rider. It set by as little as 1/32". This does not explain the 3rd lever but if you try to use it you would see what it does.
