Cibola Knob

[Digginman]

I've been using my new Cibola a few times now. I love this machine. I do have one concern. I don't know how or why it's happening, but my Disc Knob seems to want to increase. I usually set it at "Iron" and alot of times I will notice it's at nickel or higher. It's not loose, it's actually being turned. I must be doing it somehow. Is there any way to prevent this besides taping it down??

Just put a o-ring under the knob, this is common thing.

Yep, what he said. Loosen the set screw on the knob and pull it off. Select an o-ring slightly smaller than the diameter of the shaft. Push it on and replace the knob. Hold the knob down while tightening the set screw. An o-ring installed like this is useful for 2 purposes. One, gives plenty of "drag" on the knob to hold its settings; two, helps prevent water and dust from getting down the shaft hole into the MD's control box.

Thanks for the advice. I'll get an o-ring, tomorrow.
