Operating Procedures
Step 3
From the freezer door, remove design caps, pivot pins,
draw handles, and draw valves. Remove all o- rings.
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 4
Remove the large o- rings, front bearings, and guide
bearings from the back of the freezer door.
Step 5
Return to the machine with a small amount of cleaning
solution. With the black bristle brush, brush clean the
rear shell bearings at the back of the freezing
cylinders.
Note:
If the drip pan was filled with an excessive
amount of mix, this is an indication that the drive shaft
o- ring of the beater assembly should be replaced or
properly lubricated.
Step 6
Thoroughly brush clean all disassembled parts in the
cleaning solution. Make sure all lubricant and mix film
is removed. Take particular care to brush clean the
draw valve cores in the freezer door. Place all the
cleaned parts on a clean, dry surface to air dry
overnight.
Step 7
Wipe clean all exterior surfaces of the machine.
