The document details the installation procedure for the Automatic Primer Feed (APF) body, which involves lowering the operating handle of the Pro-Jector to insert the APF assembly over two mounting holes in the main casting. Once inserted, the handle is returned to its raised position to center the primer arm cup in the subplate before tightening the screws.
The guide also covers adjustments for the primer shutoff assembly and the primer arm cup. It explains how to attach the shutoff spring correctly and provides steps to adjust the APF cam and body screws to ensure the primer cup is centered within the housing hole, which regulates the movement required for positive primer pick-up.
Lower the operating handle and insert the entire APF assembly over the two mounting holes in the main casting.
Allow no more than the thickness of the spring between the bottom of the housing and the bottom of the spring.
Remove the primer tube housing and adjust the APF cam until the primer cup is centered in the APF body primer tube housing hole.
