This section describes maintenance procedures which will increase the longevity and efficiency of your additive feeder. Perform them at the regular intervals listed on the checklist on the previous page.

Material Cleanout/Changeover

Caution! Never put hands or tools in or near the auger assembly when power is connected!

Do not wear gloves or loose clothing when working near the auger assembly!

1.Remove all remaining additive from the supply hopper by opening the cleanout hatch. The motor assembly must be disengaged to fully open the cleanout hatch.

2.Re-engage the motor assembly and run any remaining additive out of the feeder by opening the calibration hatch and holding the three-position motor switch in the MANUAL position.

3.Disengage the motor assembly and remove the auger. Release the insert by pulling the auger insert release knob on the side of the material transfer tube assembly. Slide the insert out through the motor end of the transport tube. Clean both the auger and the insert.

4.Clean the interior of the supply hopper and any additive remaining in the calibration or cleanout hatches.
