6-3 Corrective 
Maintenance 
This section provides you with the information necessary to correct or repair any issues 
which might appear during the normal operation of your additive feeder.  Although we have 
listed how to perform these procedures, it is recommended that you call the Service 
Department to have any in-depth maintenance performed. 
Auger Assembly Changeover 
Our additive feeder auger assemblies may be removed and installed without tools.  All auger 
sizes are interchangeable. 
Caution! 
Disconnect and/or lock out electrical power before removing an auger 
assembly or performing any service or maintenance. 
 
 
Removing Auger Assembly 
1.   Empty the supply hopper by swinging open the cleanout hatch. 
2.   Disengage the motor assembly from the auger by removing the motor mount 
linchpin and swinging out the motor. 
3.   Pull the auger out. 
4.   Swing open the calibration hatch. 
5.   Release the UHMW auger insert by pulling out the spring loaded plunger and 
turning it a quarter turn. 
6.   Slide the auger insert out through the transport tube assembly. 
7.   Clean any remaining additive from inside the feeder. 
Installing Auger Assembly 
Make sure the insert and auger to be installed are a matching set. 
1.   Slide the UHMW insert into the material transport tube.  Line up the insert’s 
groove with the locking pin in the side of the transport tube.  Be sure the locking 
pin is retracted. 
2.   When the locking pin is aligned with the insert’s groove, release the locking pin.  
The locking pin will ride in the groove as the insert is pushed into the transport 
tube. 
3.   When the insert is in place, the locking pin will snap into a retaining slot in the 
insert’s guide groove. 
4.   Insert the matching auger into the insert and line up the motor coupler with the pin 
on the end of the auger. 
5.   Fasten the motor assembly into place by restoring the linchpin to its original 
position. 
6.   Close and secure the calibration and cleanout hatches.
