About the Door Seal System On 60044_ and 72044_ Divided Cylinder Models
Your machine uses a compressed air system to hold the shell door against the shell when the
machine operates. This system operates at 50 PSI (345 kPa), which is set on a pressure
regulator. At this pressure, the system must push the door against the shell with sufficient force
to prevent a door leak. If a component of this system is severely worn or damaged, a door leak
can occur. At the intervals given in the maintenance summary, look at the machine in operation.
If there is an indication of a door leak, it is necessary to repair the door seal system. Speak to
your dealer or Milnor.This is not routine maintenance.
Supplement 4
About the Push-down System On Divided Cylinder Models
Your machine uses a compressed air system to hold the shell tight against the base most of the
time that the machine operates. The shell is released when the machine is in the extract
sequence. This system operates at line pressure. When this system starts or stops, the shell must
smoothly move down or up approximately three inches (approximately 80 mm). If a component
of this system is severely worn or damaged, these conditions can occur:
• The shell goes down or up with an irregular movement.
• The shell hits the housing when it moves in the wash sequence.
At the intervals given in the maintenance summary, look at the machine when it operates. If one
or the two of these conditions occur, it is necessary to repair the push-down system. Speak to
your dealer or Milnor.This is not routine maintenance.

correct quantity and quality of oil for correct operation. The oil level can decrease and the oil
can become dirty as a result of operation.
Change the oil at the intervals given in the maintenance schedule. You can slowly add oil
through the fill port with a tube and hand pump. It can be hard to put the tube fully in the
cylinder because of the internal spring. You can add oil quickly through the drain port. Put a
needle valve on the drain port and connect a hand pump.
Examine the oil at the intervals between oil changes given in the schedule. Examine the oil as
follows:
1. Do not remove the oil fill plug. When you open the drain port, this will help to prevent a
fast release of oil.
2. Release a small quantity of oil into a cup from the drain port.
3. If the oil is dirty or does not look correct, change the oil.
4. If the oil is good, add oil through the fill or drain port until oil comes out of the fill port.
