Introduction
This Illustrated Parts Breakdown (IPB) Manual contains the information necessary to locate and identify
assemblies, sub-assemblies, and specific parts of the 1800 Overhead Projector.
Part Numbers
All components available on a replacement basis are listed with their 3M identification number. The
parts identification list opposite each illustration provides the description adequate to identify
components. If the component is available only as part of the next higher assembly, the description
column provides the next higher assembly description or identification number.
Locating and Identifying a Part
If physical appearance and general location of an item are known:
1. Use the IPB Section Titles to help determine which assembly or sub-assembly includes the item.
2. Refer to the view for the assembly or sub-assembly and locate the item on the exploded view. Match the part
callout number to the corresponding number in the parts list.
3. Parts shown inside a dashed box can only be ordered as an assembly. Any part or mounting hardware shown
outside the box is not included with the assembly.

Identification Plate is divided into the following
components:
1. Product Name: The specific version number of the
