Do the maintenance in

Section 3.1.1 : Maintenance Summary, page 13

to make sure that the ma-

chine is safe, keeps the warranty, and operates correctly. This will also decrease repair work and
unwanted shutdowns. Speak to your dealer or the Milnor® Service department if repairs are
necessary.

WARNING:

Mechanisms —

can can pull in and mutilate body parts.

Do not service the machine unless qualified and authorized. You must

clearly understand the hazards and how to avoid them.

Do not service the machine with power on except when explicitly

called for in the service instructions. Use extreme care when working near
moving components.

Replace guards and covers that you remove for maintenance.

If you use software to keep the maintenance schedule for your plant, add the items in the follow-
ing maintenance summary to that schedule. If not, you can put marks on a calendar that work with
the tables in the maintenance summary. See

Section 3.1.6 : How To Show the Maintenance On a

Calendar, page 20

Maintenance Summary

BNUUUH01.R02 0000334004 A.7 A.26 A.35 10/25/21 1:20 PM Released

Each of the following sections is for a type of maintenance. For example, the section “Guards
and Related Components” says “Examine these items. If an item is damaged, missing, or has the
wrong setting, correct this discrepancy immediately to prevent injury.” A table in each section
identifies the applicable items and the frequency. The “More Data” column gives special instruc-
tions if necessary.

* If the machine operates more than 12 hours each day, do the “day” items two times each day.
Do the other items at the given hours or on the days that you show on a calendar (see Section 1).

Do all items in all sections for the maintenance intervals that apply (for example, day, 40 to
60 hours, and 200 hours).

TIP:

The maintenance summary has many links to the sections that follow the summary.

These sections give more information about the maintenance items. After you learn this
information, it is only necessary to look at the summary to do the maintenance.
