I bought both of my routers new the same day, after about twenty minutes of use in my Crastsman router table, using a Craftsman 6.5 h.p. shop vac, both my routers got stuck. I attempted to use strap wrenches to break one loose with nothing good happening. I went to sears and raised hell until I got a list of numbers to call. Sears sent it to a repair shop, and the repair person used a 36" pipewrench on the adjusting ring until he broke the motor housing (which freed up the adjuster) They wanted to charge me $69.58 for the repair, I refused and took it home. The Sears Store manager (LaCrosse,WI)finally agreed to return my money. (with receipts)
That model line has been discontinued. Saw dust in the treads of the adjuster caused the problem. I took the first one apart, but when you get to the last three parts; the aluminum base, Plastic motor housing and adjusting ring, I couldn't find a way to get it apart any farther. There is a pin under the left handle that prevents the motor housing from rotating in the base, but couldn't drill it out without messing up the aluminum base portion.
Sears has had to have had thousands of complaints on this problem. I knew I couldn't have had the only two that locked up.
, I think Sears needs to own up to this issue and post a 100% refund recall.
