Operating Procedures
The Model 490 stores 20 qt. (18.9 L) of mix in the hopper.
The mix flows by gravity through an air tube down into
the freezing cylinder.
Instructions begin when we enter the store in the morning
and find the parts disassembled and laid out to air dry
from the previous night's cleaning.
The following procedures will show you how to assemble
the parts into the freezer, sanitize them, and prime the
freezer with fresh mix in preparation to serve your first
product.
If you are disassembling the machine for the first time, or
need information to get to this starting point in our
instructions, turn to “Disassembly” on
page 6-7 and start
there.
Assembly
Note: When lubricating parts, use an approved food
grade lubricant (example: Taylor Lube).
1. Lubricate the groove and the shaft portion that comes
in contact with the bearing on the beater drive shaft.
Slide the seal over the shaft and groove until it snaps
into place. Do not lubricate the hex end of the drive
shaft. Fill the inside portion of the seal with 1/4 in.
(6.35 mm) more lubricant and evenly lubricate the flat
side of the seal that comes in contact with the
bearing.

2. Insert the drive shaft through the rear shell bearing in
the freezing cylinder and engage the hex end firmly
into the gear box coupling.

WARNING! Use extreme caution when
handling the beater assembly. The scraper blades are
very sharp and may cause injury.
3. Before installing the beater assembly, check the
scraper blades for any signs of wear or damage. If a
scraper blade is nicked or worn, replace both blades.
