DW017 24Volt Miter Saw

Rework Procedure for Reverse Running

  1. Tools needed:
  2. #2 Phillips screwdriver
  3. pliers
  4. Charged 24V battery
  1. Determine if unit is running in reverse. This can be accomplished by inserting a charged battery into the unit and observing the direction of blade rotation. When facing the visible side of the blade, the blade should rotate clockwise.

Alternatively, the motor cover plate can be felt or observed to see if the motor has been mounted correctly. To make this easier, release the head lock to raise the head. If there are notches on the cover plate, then the motor should run backwards. Verify direction of rotation with battery before proceeding. Be sure to remove the battery before continuing with the repair.

Correct assembly

Will Require rework (re-wiring)

  1. If it is determined that a saw is running backwards, then the wiring to the brushes needs to be reversed. The process is easier to accomplish if it is beveled, and the sliding fence is slid out of the way. Loosen the bevel knob to do this.
  1. Remove the 2 screws securing the end cap with a #2 Phillips bit. See pictures below for the initial wiring condition, and the corrected wiring. You have to first remove the brown wire from the double connector. Then swap the double terminal with black wire and the purple wire as shown (purple will connect to “+” black will connect to “-“). Re-attach the brown wire to the double terminal. The brown wire may be a little tight, but make sure that the wire still has some play. In a worst case scenario, the handle of the saw may have to be opened to give the brown wire more play.

Initial condition

Brown & Purple wire removed

Black wire and double terminal re-located to bottom terminal “-“. Note that free terminal faces out.

Brown wire re-attached to double terminal. Purple wire attached to upper terminal “+”. Note brown wire passes under purple wire.

  1. If either of the faston connectors become loose during this operation, they will need to be tightened. Do this by carefully bending the sides of the fastons with pliers as shown. The amount of bending necessary is very little. Do not overbend, or the terminal will be very difficult to re-assemble.
  1. After the repair is completed, reattach the end cap, return the saw to zero bevel, and make sure to secure the bevel lock. Also slide the sliding fence right and tighten the knob. Insert the battery and test for correct rotation of blade. Remove battery.
