smoothly and dispense at 18°F
(-8°C). If the product comes out in
spurts, slowly, or if there are popping
sounds, check to see that the mix
transfer system is operating properly.
CAUTION
To avoid electrical shock or
contact with moving parts,
make sure all switches are
in the "OFF" position and
that the main power supply
is disconnected. Some
freezers have more than
one disconnect switch.

switch in the "OFF" position, check
the belt tension (1/2" deflection with
approximately 5 pounds of pressure)
and use a straight edge to check
pulley alignment.
