I am having what sounds like some of the same problems, have been working on the machine and have come to find out that during the manual tool change the release cylinder releases fine, but during a ATC the cylinder does not travel enough and the arm yanks the tool or the tool falls out.
Currently my thoughts are that I let the oiler run dry and the cylinder is not moving fast enough for the time allotted. So I have put some oil in and shot some wd40 in the air lines at the manifold, but it does not seem to be helping.
Any thoughts?
BTW, to adjust the length of the cylinder end, there is a lock nut on top of the piece that presses against the spindle. Take the belt off, pull the spindle motor out some and you can get a wrench on the top lock nut. BTW again, unless someone has a smarter idea it is easier to pull the spindle out and adjust it with a socket and a wench.
