    • Remove the rubber bumper from the hammer case cover on the front of the impact driver. Grab the back edge of the bumper and pull it forward over the end of the impact driver.

    • When replacing the bumper, be sure to align the tabs on the inside of the bumper with the four slots on the hammer case cover.

    • The hammer case cover has two large tabs that seat into the groove around the front of the hammer case. Using a prying tool or flat head screwdriver, gently pry each tab out of the groove while pulling forward on the cover. After both tabs have released, the cover should slide off the front of the hammer case.

    • Turn the impact driver so that its right side faces up. Remove the eight identical Phillips screws that hold the two sides of the housing together.

    • Gently pull up on the side of the housing. Use a prying tool or flat head screwdriver to separate the two sides of the housing. Be sure to keep the yellow battery terminal seated in its slot on the lower housing.

    • When the housing is almost open, the forward/reverse change lever will catch on a round tab at the top of the trigger switch. Gently lift up on the trigger while pulling the housing up and towards the rear of the impact driver, allowing it to come free.

    • When reassembling the impact driver, make sure to set the round tab of the switch into the groove on the forward/reverse change lever.

    • Notice the orientation of the blade connectors and the wires connected to them. When reassembling the impact driver, be sure to route the wires in the same way. The blade connectors should have their wires facing forward.
