scraper blades, and drive shaft(s) from the freezing
cylinder(s). Take these parts to the sink for cleaning.

Brush Cleaning
Step 1
Prepare a sink with an approved cleaning solution (ex-
amples: Kay- 5r or Stera- Sheenr). USE WARM WA-
TER AND FOLLOW THE MANUFACTURER’S SPE-
CIFICATIONS. If another approved cleaner is used,
dilute it according to the label instructions. (IMPORT-
ANT: Follow the label directions. Too STRONG of a
solution can cause parts damage, while too MILD o f a
solution will not provide adequate cleaning.) Make
sure all brushes provided with the freezer are available
for brush cleaning.
Step 2
Remove the seal(s) from the drive shaft(s).
Step 3
From the freezer door(s) remove:
S gasket(s)
S front bearing(s)
S pivot pin(s)
S adjustable draw handle(s)
S design cap(s)
S draw valve(s)
S prime plug(s)
S 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 o- rings from the air tube(s) and air
orifice(s).
Step 5
Return to the freezer with a small amount of cleaning
solution. Brush clean the rear shell bearing(s) at the
back of the freezing cylinder(s) with the black bristle
brush.
