This is the first time repairing this tool, and I removed more parts than necessary.
In order to replace the Constant Force Spring, I had to remove the nailer magazine from the nailer body. This task was not difficult. I used a socket wrench and an alex wrench to remove the screws. Once the magazine was out, I made a mistake removin g the part in back of the magazine that holds the spring while you load the nails. That was not necessary because the Force Spring and housing comes out of the front of the magazine. It was very easy to replace it with the new spring.
