Operating Procedures
The Model 490 stores 20 quarts (18.9 liters) 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 the “Disassembly”
instructions in this manual and start there.
Assembly
Note: When lubricating parts, use an approved food
grade lubricant (Example: Taylor Lube).
Step 1
Slide the o-ring into the first groove on the drive
shaft. 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” more lubricant and evenly lubricate the
flat side of the seal that comes in contact with the
bearing.

Insert the drive shaft through the rear shell bearing
in the freezing cylinder and engage the hex end
firmly into the gear box coupling.
Figure 4
USE EXTREME CAUTION when handling
the beater assembly. The scraper blades are very
sharp and may cause injury.
Step 2
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.
Check the scraper blade clips to make sure they are
not bent and the slot is even for the entire length of
the clip. Replace any damaged clips.
