SOURCE: dewalt demolition hammer stopped hammering.

could be a few problems, the striker could be stuck from debris or the ram might be hydraulically locked. they make a rebuild kit for this tool if you are mechanically inclined. I would suggest first going to their site and downloading a parts breakdown and there you will find what is involved and the parts listing. It is "dewaltservicenet.com" and on the left hand side type in your model number and then follow the links to download this. Let me know if you need more assistance.

Dewalt demo hammer, when switched on the motor speed surges up and down constantly. What is wrong?


Check the brushes first. If they are worn or sticking they could cause this.

If the brushes are fine and not worn down then it is most likely the electronics/ variable speed module.

Dewalt d25940k is a demolition hammer whith drill too?


No, the D25940K is not a Rotary Hammer. It is just a Demolition Hammer. (Jack Hammer). You can turn the chuck to adjust how your bit sits but that is it. Follow this link to the manual for this tool. http://www.dewaltservicenet.com/documents/English/Instruction%20Manual/581735-00,D25940.pdf
