Here's one more tip about the two routers Chicago and Homier, they are both ok routers but you must not run them to long and get them HOT.
They both come with a extra set of brushs, they do this because they know they are going to fail.
If they get hot and they do because they don't put a fan in to cool them down ,I can see why when they sell them so low and a 10 cents is a big deal.
This what they do when they get hot the spring that's on the brush wire with fail that's to say because it's a spring it can't take the heat and will lose it's spring and then the arc will cook and burn up the brush or it will just stop running because the brush can't stay in place.
The key to keep them working is not to work them to long or to say use a short pass and then let them cool down.
The brush caps can be tricky to get out, a little cutting fuild and a inpack driver will free them but you must take care when you hit the cap, it's plastic
.
Hope this helps someone that has one , by the way I have 4 of them and many of the Chicago/Homier tools are the same way .
Just a Note... my son just cooked one last weekend (4" grinder) and I just got it repaired today.
