Pete, The fingers on the end of the drawbar that grab the retention knob (pull stud) are spring loaded and hold the tool even when the drawbar is pushed down. The arm just pulls down enough to overcome the spring force to remove the tool and up hard enough for the tool to snap into place. Honestly, I was surprised that more drawbars don't work this way, but considering everyone's reaction, I guess few do.
Kirk, I'm going to guess lack of lubrication. One of the lower flexible oil lines was age-hardened and broke. So until it (and the Bijur compression fittings) comes in, the pump is disabled. Obviously, aside from short test runs we won't be running the machine until that is rectified.
