Hi,
I posted this on another site but didn't get any info that would help solve my problem. Hope someone here can help!
I have a variable-speed Bosch Colt I picked up a couple of years ago and have used for only a few projects. It worked flawlessly for me on them.
I haven't used it in the past year or so - it's just been living in its case. Yesterday I pulled it out for a quick job and when I turned it on, the variable-speed feature had become "self-engaging"... sort of like the Craftsman routers with the "automatic height adjustment" feature.
When I turn it on, the speed will run all over the place (this is just holding the unit in my hand - I'm not cutting anything). I blew out all the vents with compressed air, removed & inspected the brushes (although I wouldn't know a good brush from a bad one if my life depended on it) and just couldn't get it to behave.
Any motor experts out there have any insight as to what would be causing this problem and have any solutions on how I can fix this myself (I'm going to be mighty ticked off if I have to pay someone $50 + to fix an almost-new router I only paid $80 for...)
Thanks in advance for any advice anyone may be able to provide.
Cheers!
Scott
