My dremel 3600 oscilating tool has a problem with the speed control. It runs slugish and low power, after messing with it for a while I find if I jam another blade betwwen the rear of the housing and the control knob( pushing the know forward) it seems to power up to where it should be.

clean the slots that hold the brushes, sometimes they get cloged and the springs do not push the brushes all the way to the armeture.

Unfortunatly Dremel who is owned by Bosch has discontinued that tool and parts are no longer available.

SOURCE: My Dremel tool has intermittent power.

You can go to any repair facility and buy a replacement cord making sure of the wire guage and conductor (2 or 3) what you can do is make a wiring diagram and remove the old cord and holding the cord about 10 inches from end pull one wire at a time and if there is a break it will pull out to confirm your suspicion. Let me know if you need any more help and if I have answered your request would you please rate this response accordingly and thank you.

hello. You loosen the arbor at the base of the shaft closest to the tool. There is a tiny wrench in the kit that came with the dremel, or you can use a pair of pliers to loosen it. Joe
