Using the Illustrated Parts Lists

To order parts, call the Nordson Customer Service Center or your local Nordson

representative. Use these five-column parts lists, and the accompanying illustrations, to

describe and locate parts correctly. The following chart provides guidance for reading the

parts lists.

The number in the Item column corresponds to the circled item number in the parts list

illustration. A dash in this column indicates that the item is an assembly.

The number in the Part column is the Nordson part number you can use to order the

part. A series of dashes indicates that the part is not saleable. In this case, you must

order either the assembly in which the part is used or a service kit that includes the part.

The Description column describes the part and sometimes includes

dimensions or specifications.

The Note column contains letters that refer to notes at the bottom of

the parts list. These notes provide important information about the

part.

The Quantity column tells you how many of the part

is used to manufacture the assembly shown in the

parts list illustration. A dash or AR in this column

indicates that the amount of the item required in the

assembly is not quantifiable.
