To ensure that the bearing inside the extruding head does not exceed the wear tolerance
of .02", follow the instructions below.
1) Remove the front panel. Move the power switch to the "OFF" position, then unplug the
unit from the electrical outlet.

4) Remove the bolt (if applicable) or cutter from the auger and lift off the cutter and washer

Move the auger towards you and then try to insert a .02"
round stock or pin gauge in between the back side of the
auger shaft and the bearing surface. Check several locations
around the auger shaft. If the gauge goes between the shaft
and the bearing at any point or if the bearing is scratched
or cracked, both the top bearing in the extruding head and
the lower bearing in the lower housing should be replaced.
Instructions for removing the extruding head and lower
housing are located later in this procedure.
