Step 1: Ensure the spring is installed on the shaft.

Step 2: Screw the pin into the shaft about half-way. Use purple vibraTITE 111 on the threads. This will prevent the pin from backing out of the shaft, which can cause problems. Use a 3/16" wrench to hold the flats of the shaft and snug the pin into place. Vice shaft with rubber grips to prevent scarring of the shaft. Do not overtighten the pin into the shaft – just snug it. The vibraTITE will do the rest.

Step 3: Drop the shaft and pin into the die body and screw on the top cap of the die. You will feel the spring tension start. Turn the top down and leave a gap of about the thickness of a dime. Leaving this gap will ensure the spring will work properly.

Step 4: Turn the die down into the tool head far enough so that the lower threads on the die are below the bottom of the tool head.

Step 5: Install the bottom case holder cap (collet) with or without the rifle case guide in place.

Step 6: Raise the die and bring your tool head all the way down. Turn the die down to touch the shell plate. Then back it out about a full turn.

Step 7: Decap a case. When you hear the primer flick out you know you’re ready to go.

If you have the decapping sensor, set the housing on the top of the die by sliding it down until it stops.

If it’s a plug-in sensor, plug the sensor connector into the module. All set to go! When you run into a bad case, the sensor will shut down your drive and save you time and pins.
