I'm currently staying at my mother-in-laws for the next month and since I've been here I've had some issues with my Flex 3401.
Let me explain...
I'll be using the Flex and everything will be fine, but then all of a sudden it will drop rpms. This is without me pressing down too hard or hitting the speed setting or anything like that. It's almost like it's not getting enough power. Sometimes it'll speed back up and other times it won't. It has never completely died, it's just almost as if it's not getting enough juice.
I'm not an electrian, but is it possible that the extension cord (hers) that I'm using isn't very good or something? Usually it slows down for a second and picks back up and sometimes goes back and forth between the two, but today, after detailing for about 15 minutes it started to slow down and stay that way.
I've had the machine for a few years, but I've only used it on maybe 10 seperate occassions. It's clean and well kept. It never did this anywhere else but at my mother-in-laws.
I haven't tried a new cord yet; I need to buy one. Any reccommendations? Is this the most likely problem? She lives in a five year old house, so it's not like it's plugged into anything shady or something.
