Remember it has a ER collet. If you have never used one, read up (or YouTube it) on how to correctly install one as there is nothing in the manual!

yes, one good video is this one:

ER collets have a mark which has a purpose explained in the video.

ER collets are not mounted the way a trim router collet is mounted. Most people put the collet into the axle of the spindle and then they put the collet nut over it. That is definetely wrong! An ER collet has a groove that goes all the way around near the top of the collet. The corresponding collet nut of an ER collet has an excentric extractor ring or offset lip inside. It is absolutely mandatory to fully engage (clip in) the collet inside the nut before you tighten it onto the holder, as shown at this moment of the video “ER Collets | 5 Things to Know for Beginners”.
