1. Upper Bearing Wear Check
To ensure that the bearing inside the extruding head does not exceed the wear tolerance
of .02", follow the instructions below. See Fig. 3.
1) Move the control switch to the "OFF" position, then turn off the power supply. Remove
the front and top panels, then move the power switch to the "OFF" position.
2) Remove the front cover of the storage bin. Remove spout B,
then remove spout A and the cutter. See Fig. 2.
3) Grasp the top of the auger and move the
auger towards you, 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
housing should be replaced. Instructions for
removing the extruding head and housing
are located later in this procedure.
Note: Replacing the bearing requires a bearing press adaptor. If one is not available,
replace the whole extruding head and housing.
4) Replace the cutter, spout A, spout B, and the front cover of the storage bin in their
correct positions.
5) Move the power switch to the "ON" position, then replace the panels in their correct
positions.
6) Turn on the power supply, then move the control switch to the "ICE" position to start the
automatic icemaking process.

1) Move the control switch to the "DRAIN" position and drain all of the water from the
evaporator.
2) After the water has stopped draining, move the control switch to the "OFF" position, then
turn off the power supply. Remove the front and top panels, then move the power switch
to the "OFF" position.
3) Remove the front cover of the storage bin. Remove spout B, then remove spout A and
the cutter. See Fig. 2.
