I bought a dewalt ROS about a year ago. I have only used it a handful of times so far but I noticed that the rotation of the head seems fairly easy to stall. It still vibrates, but the rotation can be stopped fairly easily.

I know that lightening the pressure would lessen this problem but I was wondering if this is just par for the course or do I have a lemon. I would love to be able to speed up the process with a litter more pressure for rough sanding.

I have a DeWalt ROS and love it. I have noticed it will stop spinning with heavy pressure. I just back off a little bit and not be in such a hurry. Does this with heavy grit paper, 80-100. Finer grits, 150-320, it don’t stall at all. Just take your time and it will get the job done!

A ROS sander should not be rotating, hence than name ROS. It should look like it is vibrating instead of rotating like an old drill sanding disk. Most good ROS have a feature that prevents rotation until the sander is placed on the work surface.

You should not be putting on hard pressure when using a ROS, arm weight is usually enough.

+1 on this recommendation. I just posted a review for my Dewalt sander I haven’t been able to bog down the motor through normal use. For the most part, the weight of the tool itself is all that’s needed for efficient sanding.

Thanks all. I was just looking for some affirmation here. Up until I bought the Dewalt, I had only been using a vibrating sheet sander. As far as the Dewalt goes, its a nice sander just in case anyone is looking for one. Dust collection is pretty darn good even with only the bag attached.

Thanks again all
