1. I examined the replacement parts.
2. The power chord supplied by your company did not include the required strain relief.
3. I modified the new power chord by cutting off the strain relief from the old chord set and installing it on the new chord set. (24 hour cure time for the epoxy used to attach the strain relief.)
4. I removed the defective switch and chord set.
5. Since no instructions were included, I contacted your customer service to obtain a schematic of my drill.
6. No schematic was available from your company, but I was given the phone number of MAKITA customer service who supplied the required documentation.
7. The compression connectors on the switch required several attempts to attach the power chord and additional internal wiring to the switch. (There was little tolerance to insert each wire into the mounting holes on the switch utilizing a jeweler's screw driver.)
8. I reassemble the components on the drill body including the new switch dust cover. (A slot was not provided on the dust cover to allow the rotation direction control to protrude.)
9. I then successfully tested the drill.
