Is there a lifespan on the rotaries use? i saw a post about people having to change/replace something in their rotary, but i cant find the post anymore. what is it thats getting repaired and how do i know when i would need to repair mine?
 
It was probably the motor brushes which are very easy to change. You'll get quite a bit of use out of one before you have to worry about it and unless you're a pro you might never have them wear out. The main symptom of brushes getting worn is it will either stop working or start getting erratic.

Usually it just won't start, but it could start out as erratic speeds, cutting on and off, etc. It's pretty easy to take the brush caps off, pull the brushes out, and examine them for length. If they're short little nubs then you know they are worn. Look at the following diagram for a Makita 9227; item 42 is the brush and item 43 is the brush cap that you remove to take out the brush:

I bought a Makita because my friend owns a bodyshop and has been using the same Makita for over 10 years.

Eliot, AKA John,



This is my first post here, but I noticed your link in your signature to the Real story on Eliot Ness! I know my post is off topic, but I must commend you publicly for that reference. What a read! Thank you!



Now back to the regularly scheduled posts!:usa



PS: Where do I start in this BBS?
 
Porter Cable makes good stuff. Ive pounded mine for 6 years and she's still going. Although she will probobly be placed on the junior varsity, as I suspect Ill be ordering a Flex soon
 
If i was you, get a name brand as replacement brushes are easy to find and cheap ($6-$10 a set). I got my generic vector polisher.. actually 3, that i have worn out the brushes to a small nub and cant find any brushes that'll fit it.. one lasted 2 years and this one, about over a year.. however i have it on all day long, 5 days a week, as thats all i do (scratch removal, polishing, no detailing interiors).
