Questions & Answers

When I use my drill it smells like wires getting hot the motor runs but some time it not as fast as normal some time it sparks thanks ed
Ed for model number Dc985 ka
When you smell that the drill is burning, it can be caused by the overheating inside the tool. Usually, it is caused by the brushes that wear down as we use them repeatedly for a long time. ... The power drill will then work again. The overheating problem can also be caused by other reasons related to the motor. part number 603754-01 is the compatible part for your model Hope this helps

Smoking and sparking drill
Easy fix. I did not know the new motor already has the brush set in place ( I also ordered a set of brushes). Now I have a back up set of brushes. After taking the drill casing 1/2 off, I used my cell to take pictures just in case I had problems getting the drill back together. I will say this as a piece of advice for all: Any time you remove any screws from a plastic case, when you are putting the tool back together you should always first turn the screw backwards until you feel a slight click from the screw trying to seat itself. Then change direction to clockwise to drive the screw in. This will keep you from striping the plastic case screw hole.
