Dan Page Posted December 24, 2019 Report Share Posted December 24, 2019 I have an ex 21. The tension knob on the back of the saw keeps moving. I know it has been discussed on here but can't locate it so thought I would just bring it up again. My saw is 6 or 7 years old. I have played with it and must be missing something. Thanks for any help OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
kmmcrafts Posted December 24, 2019 Report Share Posted December 24, 2019 This is an issue I had with my EX-21 .. Here is the topic I posted with my fix method.. I have run over 100 hours since I fixed it and it hasn't moved one bit.. other than when I intentionally move it.. Somewhere there is another discussion about this and the fix was just wrapping a rubber band around it.. Probably a much easier / quicker method.. I just like doing everything the hard way.. Makes my life more interesting.. Merry Christmas OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
NC Scroller Posted December 24, 2019 Report Share Posted December 24, 2019 (edited) Dan, I think this is the tread you are looking for. It shows the rubber band trick Kevin mentioned.

Dan Page Posted February 6, 2020 Author Report Share Posted February 6, 2020 Ok I tried to reach that nut on my saw and thought I had it where it wouldn't move and it worked for a while then started moving again. Sunday afternoon I tore into it a little farther where I could reach it better and put some loctite on it. Used it for an hour or so this evening and so far so good. Fingers crossed it fixed the issue. Thanks for all the help kmmcrafts and OCtoolguy 2 Quote Link to comment Share on other sites More sharing options...

He said the threads get worn over time.. and eventually gets loose.. Loc-tite will help tighten things up but eventually it'll need it again and or just replace it..

I know this is not the "approved" method but if you can see where the nut should be at when properly adjusted, take the threaded shaft out and lightly peen the threads in that area to "fatten" them up a bit. It might save having to buy a new shaft and nut. kmmcrafts 1 Quote Link to comment Share on other sites More sharing options...
Fish Posted February 7, 2020 Report Share Posted February 7, 2020 You could try using Teflon tape. Wrap it around a few times. OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
