Thanks Kelton...
Thanks for confirming that. Kevin, I have a 510 with an emtor that was missing it’s lil red plug. I put a round end screw in it and painted the top of screw red. I also noticed that the short red-tipped screw from the Handi-Sharpener works too.
NOW, I’ll be really curious to see what the experts on VacuumLand will think of my “quick fix” and if that would be considered acceptable or if only finding the real deal would be OK. I really am curious...I’m satisfied as it looks good from a distance and I think that only members of this site would notice.
