Prepare a sink with an approved cleaning solution
(examples: Kay--5R or Stera--SheenR). USE WARM
W ATER AND FOLLOW THE MANUFACTURER’S
SPECIFICATIONS.
IMPORTANT: Follow the label directions. 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 br ush cleaning.
Step 2
Remove the seal(s) from the drive shaft(s).
Step 3
Remove the scraper blade clips from the scraper
blades.

bearing(s), pivot pin(s), draw handle(s), draw valve(s),
prime plug(s), and the design cap(s).

Remove the flare line(s), suction line( s), a ir line(s)
pressure line(s), relief assembly(s), and check
valve(s).
Step 6
Disassemble all parts and remove the 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. 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.
