Lubrication
Bearings & Seals
Main Bearings on the ice flaker must be lubricated every 3 months with a FDA approved edible grease.

through the inspection (service) opening, the bottom bearing is lubricated through one of the ribs
located on the front of the machine in the lower right corner near the water sump. (O

Speed Reducer Lubrication
Grease Fitting
The speed reducer must be lubricated (greased) every six months with a standard bearing
grease ( not food grade).
Oil Change
The oil in a new speed reducer should be changed at the end of 250 hours of operation.
Under normal conditions, after the initial oil change, the oil should be changed after
every 2,500 hours, or every six months, whichever occurs first. Periodic examination of
oil samples taken from the unit will help establish the appropriate interval.
Low Temperature Oil
When operating the ice flaker in low ambient temperatures, (colder than 50 ° F). The
gearbox oil must be changed from the standard mineral oil to a synthetic oil. The
synthetic oil is appropriate for lower temperatures as well as having a longer operating
life resulting in less frequent oil changes.
Mechanical Cleaning
Refer to page 57 for cleaning procedure.
