How do I adjust trickle speed on a Lock-N-Load® Auto Charge, serial number 2840 or above, to prevent overthrows?

**To verify the serial number of your machine, simply turn it over. It is clearly stamped on the silver sticker.


Reprogram the trickle speed to a slower speed.

  1. Turn unit on and let it stabilize.
  2. Press and hold CAL button for 6 seconds. The screen will display "SET."
  3. Press the SPEED button to increase the speed.
  4. Normal factory setting is between 0.4 and 0.8.
  5. Press the UNITS button to decrease the trickle speed.
  6. After reaching the new trickle speed, press and hold BACK/CANCEL to store trickle speed and return to normal operation.

NOTE: Do not decrease the inner value lower than 0.1 or increase it more than 25.5.
NOTE: The new trickle speed is permanently stored even if the auto charge is turned off.

Often, slowing down to 0.3 or 0.4 grains is sufficient to dial the machine in.

To adjust the trickle start time:

Scale must be zeroed out with no target displayed. Additionally, if the scale is shut off or BACK/CANCEL is used, this number will need to be reset.

To increase the trickle time by adjusting the point when the unit goes from quick dispense to trickle:

  1. Turn unit on and let it stabilize.
  2. Hold MODE button for 2 seconds.
  3. The screen will display "0.2" to indicate the trickle will begin trickling approximately 0.2 grains before the target weight.
  4. Repeat Step 2 until desired start time is reached.

Standard trickle start time settings range from 0.2 to 1.6, depending on powder density.
