amount of mix, it is an indication that the drive shaft
seals, cup seals or o--rings should be replaced or

Brush Cleaning
We recommend brush cleaning all the shake parts,
then go back and duplicate these st eps (where they
apply) for brush cleaning all the soft serve parts. By
doing so, you will not confus e or interchange these
parts for assembly the next morning. Place t hepart s
in their proper place in the parts tray.
Step 1
Prepare a sink with an approved cleaning solution
(example: Kay--5Ror Stera--SheenR). USE WARM
WATER AND FOLLOW THE MANUFACTURER’S
SPECIFICATIONS. If another approved cleaner is
used, dilute according to label instructions. (IMPO R-
TANT: 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 f reezer are available
for brush cleaning.
Step 2
Remove the:
SSeal from the drive shaft
SO--rings and guide bearing from the torque
rotor
SDraw valve from the freezer door
SO--rings from the draw valve
SSpinner bearing from the draw valve
SGasket and front bearing from the freezer
door.
Note: Toremove 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. Wit h
the other hand, push the top of t he o--ringforward, 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 o--rings from the pump feed tubes.
Step 4
Thoroughly brush clean all disassembled parts and
parts trays in the cleaning solution, making sure all
lubricant and mix film is removed. Be sure t o brush all
surfaces and holes, especially holes in the pump valve
body and the small syrup holes in the shake fr eezer
door.
Rinse all parts with clean, warm water.
Step 5
Return to the freezer with a small amount of cleaning
solutionand the blac k brush. Brush clean the rear shell
bearings at the back of the freezing cylinders.
