I think I've worn out the front right toggle switch on the handle of my Lucey. It's gotten very hard to push compared to the other 4, and I'm getting a blister from having to push it so hard. I believe I heard from a dealer that this is a frequently replaced part, but I don't see it on the parts list that came with my manual, and I also can't find instructions for doing the replacement, no matter what search terms I use. I assume I can swap in a toggle switch from the rear handle and get back to work, but how?? In case it's not clear, my switch is the round black rocker switch with the white dot indicating needle up/needle down, and my issue is with the on/off function on the switch.
