Up for sale is a Lightly Used Dewalt 18 volt dw933 type 1 variable speed jigsaw, bare tool, in good working condition. Blower and orbital settings. No batteries, charger or manual. You can see in the 2nd picture I have blown out the insides of the saw and I have checked the brushes and they are fine. The blade changes on these goes like this: Raise the black knob apx. 1/4" so it looks like picture 3. Insert the jig saw blade and turn the knob clockwise until the blade is tight and then return the knob to the home position and push it down. Do the opposite for removing the blade. While you are turning the knob either way keep the knob up 1/4" or you are not moving the blade clamp. No working issues. E-mail me with any questions.
