Time

Tools Used
Screwdriver, Pliers
Parts Used
1) Remove all case screws and and top half of case noting the location of the one short screw
*Note - Be careful here to keep everything in place to make reassembly easier. The motor has to be in a certain position for the case to completely close.
2) Remove F/R Actuator
3) lift switch slightly on the actuator end and slide the pin from the actuator in the hole in the trigger
4) Slide actuator into hole on bottom of the case until the trigger seats making sure the trigger wires stay in place without binding on the case
5) Make sure everything is aligned properly and put top of case back in place noting the actuator has to align in the hole on the top of the case and checking that it seats closed at all points. Do NOT use the screws to force the 2 halves of the case together. It should squeeze together with your hands.
6) Reinsert and tighten down the case screws in a back and forth pattern making sure not to force anything
7) Test drill for operation with Forward and Reverse
8) If the F/R switch binds and won't go both directions, then take drill back apart and realign parts until case closes completely with just the pressure from your hands
