MAKE SURE CONTROL SWITCH IS IN THE
“OFF” POSITION. Failure to do so may cause injury
from electrocution or hazardous moving parts .
Step 1
Remove the torque arm, handscrews, freezer door,
torque rotor, beater assembly, scraper blades, and the
drive shaft from the freezing cylinder. Take these parts
to the sink for cleaning.

Brush Cleaning
Step 1
Prepare a sink with an approved cleaning solution (Ex-
amples: Stera--SheenR or Kay-5R). USE WARM
W ATER AND FOLLOW THE MANUFACTURER’S
SPECIFICATIONS.
If an approved cleaner other than Stera--SheenR or
Kay-5R is used, dilute according to label instructions.
IMPORTANT: Follow label directions, as too
STRONG of a solution can cause parts damage, while
too MILD of a solution will not provide adequate
cleaning. Make sure all brushes provided with the
freezer are available for brush cleaning.
Step 2
Remove the o-ring and seal from the drive shaft.
Note: To remove o-rings, use a single service towel to
grasp the o-ring. Apply pressure in an upward direction
until the o-ring pops out of its groove. With the other
hand, push the top of the o-ring forward and it will roll
out of the groove and can be easily removed.
If there is more than one o-ring to be removed, always
remove the rear o-ring first. This will allow the o-ring to
slide over the forward rings without falling into the open
grooves.
Step 3
Remove the restrictor cap, draw valve handle, draw
valve pin, draw valve, front bearing, ice buster , and
gasket from the freezer door . Remove the two o-rings
from the draw valve. Remove the o-ring and guide
bearing from the torque rotor.
Step 4
Thoroughly brush clean all disassembled parts in the
cleaning solution, making sure all lubricant and mix film
is removed. Place all the cleaned parts on a clean dry
surfacetoairdry.
Step 5
Return to the freezer with a small amount of cleaning
solution. With the black bristle brush, brush clean the
rear shell bearing(s) at the back of the freezing
cylinder(s).

Step 6
Remove the rear drip pan.
Note: If the drip pan is filled with an excessive amount
of mix, it is an indication that the drive shaft o-ring, seal
or both should be replaced or properly lubricated.
Step 7
Wipe clean all exterior surfaces of the freezer.
