To ensure that the bearing inside the extruding head does not exceed the wear 
tolerance of .0", follow the instructions below. See Fig. .

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.

) Remove the front cover of the storage bin. Remove spout B, 

then remove spout A and the cutter. See Fig. 1.

3) Grasp the top of the auger and move 

the auger towards you and then try to 
insert a .0" 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.

correct positions.

evaporator. 

) 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. 1.
