Welcome to the form.
If you bought it from a big box store I would suggest returning it because molding errors do occur and why fight with it when they can give you a replacement.
I have two Dewalt 618‘s when I bought approximately 10 years ago another one but recently used. The used one turned hard I tried it on the other router turn harder so I start comparing what the differences were between the two and it was a molding errors (plastic flash from ejection pins) use my Dremel to smooth out the spots match the other older one to tell when Should rotate up and down the motor. So it turns freely up and down the length of the motor. I also wax the inside of the plastic ring to make it turn freely up and down the motor.
good luck with your new toy.
