The F.W. ARMSTM Auto-Center Hold Down IS ONLY to be used to hold non-primed cases in place while swaging/priming. Use of this product in any other way may cause injury.
Always wear eye protection when using the F.W. ARMSTM Auto-Center Hold Down.
To set the Hold Down, install the desired shell plate you intend to use.
Ensure that no die is in the swage or priming station.
Insert a decapped case to match the shell plate you’ve installed.
Position tool head at the bottom of the stroke.
Screw the F.W. ARMSTM Auto-Center Hold Down into your tool head until the foot bottoms out on the case. You may see the case start to spin, this is a good indication the foot is touching the case.
Using a 1” wrench, tighten the supplied nut against the tool head.
Return to your press’s start position, remove the setup case.
Ensure the foot placement is correct by running a few decapped cases through. The foot should not bottom out before the press has completed a full stroke. If you need to adjust, loosen the die nut and adjust 1/8 of a turn at a time, then tighten die nut.
