In the GEN-2 upgrade, we have retooled the exit holes to incorporate machined aluminum plugs. This allows the exit holes to be manufactured with tighter tolerances and reamed to ensure a smooth surface finish. The exit hole is the most critical area for smooth function and primer flow. Upgrading to machined and reamed aluminum holes, rather than the previous injection-molded plastic ones, is a significant improvement in performance and reliability.

The PRIMAFILL GEN-2 is powered by a regular 9v battery (not included). A momentary ON switch falls naturally under your index finger as you hold the device for right-hand use, with your thumb centered on top of the lid. Hold the button down as you feed the primers into the tube, and release as soon as the last primer vanishes down the exit hole. Since this action should take 20 seconds or less, one battery charge will last for many thousands of primers.

The spring-loaded orange latches incorporated into the output posts enable you to snap a tube into place, or remove it, instantly without any twists or turns. The latch falls naturally under your thumb: you press down on it as you insert the tube up, and you press up on the latch as you extract the tube downwards. An easy and natural opposing thumb action.

Operating Instructions:

1. Ensure a 9v battery is inserted and test by pushing the power button. The device should vibrate and hum gently in your hand. Do not remove the foam pad from under the battery; it is required there.
2. Remove the lid, and position the magnetically-retained stopper to block either the LARGE or the SMALL exit hole to match your needs. Flip it over when moving it from one primer size to the other.
3. Stand the PRIMAFILL GEN-2 on a flat table, and place 100 primers on the flip tray area.
4. With the device resting on a smooth tabletop, slide it around with short, sharp motions to flip all the primers until they are all anvil-side up.
5. Replace the lid and insert a primer tube into the appropriate exit hole. Push down on the orange latch as you insert the pipe into place, and make sure it seats all the way home.
6. Hold the device in your right hand, with your index finger on the button and your thumb centered on the lid. Tilt the PRIMAFILL so that the primers bunch up near the BLOCKED exit hole (so by the LARGE when feeding SMALL primers).
7. Activate the vibratory motor by pressing and holding the power button, then gradually tilt the device towards the open exit hole (to the right for SMALL primers) so that a single (or at most a double) row is formed towards the exit hole. Also, tilt the device towards you to assist the primers in running down the exit channel to the exit hole. Do not tilt more than necessary in either axis. Try to keep the PRIMAFILL GEN-2 as horizontal as possible, while still creating sufficient motion in the primers.

• Various brands of primers will flip best with different types of agitation motion of the flip tray. Experiment to find the optimal flip tray action required to flip your primers.
• Various types of primers will slide differently, at different speeds. Some will require you to hold the device at a steeper angle to get them moving properly. Experiment a little to find the correct feeding angle best for your primers.
• If a primer hangs at the exit hole, a sharp tap with your finger on top of the lid above the hole should clear that up instantly. No need to stop the vibration of the device or remove the lid.
• If your primer tubes have an entry hole chamfer that is not well-formed or not symmetrical, this can create a ledge that primers may hang up on as they fall down into the tube. Try using the other end of your tube. Or, try rotating the tube to find the angle that allows the primers to flow uninterruptedly into the tube. You can mark that with a Sharpie on your tube so you can easily position it again in the same way. Consider deburring the entry hole on your primer tube that’s problematic.
