3.3 DISASSEMBLY OF MACHINE PARTS
WARNING
Moving machinery can grab, mangle and dismem-
ber. Place the Main Freezer Power Off/On switch in
the OFF position before disassembling for cleaning
or servicing.
Before using the machine for the fi rst time, complete
machine disassembly, cleaning and sanitizing proce-
dures need to be followed. Routine cleaning intervals
and procedures must comply with the local and state
health codes. Inspection for worn or broken parts should
be made at every disassembly of the machine. All worn
or broken parts should be replaced to ensure safety to
both the operator and the customer and to maintain good
machine performance and a quality product.
To disassemble the machine, refer to the following steps:

Loosen knobs holding the blender splash shield
bracket in place and remove the bracket (Fig.

the blender assembly and set aside.
NOTE
Support the blender with one hand while removing
the knobs on the door to prevent the blender from

3.5 CLEANING DISASSEMBLED PARTS
Disassembled machine parts require complete cleaning,
sanitizing and air drying before assembling. Local and state
health codes will dictate the procedure required. Some
state health codes require a four sink process (pre-wash,
wash, rinse, sanitize, air dry), while others require a three
sink process (without the pre-wash step). The following
procedures are a general guideline only. Consult your
local and state health codes for the procedures required
in your location.
A.
Disassemble all parts. (Refer to Section 3.4 for
the disassembly of machine parts.)
