I have just replaced a Bosch Colt with a new larger 1.25 hp Bosch GKF125CE on my CNC machine. After an approximate 10 minute run with the new router, the collet and bit were very hot. Too hot to touch for about 2 minutes. I never had this issue with the Colt. Is this a sign of future problems to come, does the router need some run time to "loosen up" or should I stop using it??
