1. Take out battery 2. Remove eight screws. Leave the 3 at the top in the handle, tape over them so they don\'t fall out. 3. Apply tape to the lock trigger to hold it down and out of the way. 4. Apply pressure to the spring pushing it down at the same time push the prong on the switch. 5. The trigger should lift off with little effort. 6. Replace all the items in reverse, taking time to let all set into place. 7. For my own felling, I placed a small amount of grease on the contact area of the spring and trigger.

The repair for the most part was easy.
Two items that posed a problem.
1) The screws to take apart the plastic handle are TORX, and one of them is recessed so deep my small magnetic torx bit, could not reach the screw head. I was able to remove the screw using a straight blade screwdriver but it took quite some time to get it out and I had to file down my straight blade to get it to engage the head of the torx screw.
2) I happen to have crimp on electrical connectors so it was not an issue to make the switch wiring connections but if you are trying to use standard \"screw on\" electrical wire nuts it may be difficult to lay the wires back into the plastic cavity. There is not much room in the plastic handle for the wiring/connection lugs to lay in.
Other than those two items the repair went fine. Good as new.
