I am puzzled by the operation of this chuck and I can find nothing on line. It appears to have been made by Pfander. This is what I have been doing:
- load collet (163E)
- fit closer loosely
- place workpiece in collet
- tighten closer so that the lever has about about 1/4" of slack
- push lever to right - this locks the collet
To remove the turned article:
- push lever to left
- undo closer with spanner
My expectation was that a collet would be mounted and closed to a sliding fit over the workpiece. The lever would then lock it in place and subsequent operation of the lever in the opposite direct would release the article.
Am I doing something wrong, or am I expecting the chuck to do something for which it was not designed?

I last used a Burnerd lever collet in a Myford Super Seven 45 years ago, which should work in a similar way. The object of the mechanism is the speed of use, so when the closer is set for a little slack, then operating the lever should clamp the work, or release using only the lever. This should work if all the workpieces are the same od.
