1. The machine assembly is broken down into 8 main sections, visible in the PDF bookmarks tab.
2. Section 8 includes links for install & setup of spindles, software, VFDs, and other accessories.
3. It is helpful to look through each section prior to beginning its assembly.
4. Each section begins with an image of the fully assembled component. If needed, refer to this as a reference while
completing individual assembly steps.
5. Each section will identify the parts and tools needed for those assembly steps, as well as which box contains those parts.
Identification of fasteners is easier if they are kept in their respective fastener bags.
6. Assembling the larger components, such as the base and optional leg kit, is made easier with two people. Though not
required, this can make the process more efficient.
7. Listed below are three types of notes you will see throughout the assembly instructions:
8. Throughout the assembly of your machine, you will use Roll-in T-Nuts. Review the instructions on the following pages for
proper use of this component.
Section Note
Section Notes can be used to denote when the section is configuration specific.

Assembly Note
Assembly Notes are used to call attention to certain parts of the assembly step. Pay attention to these as they provide
important information for a successful machine build.
Machine Configuration Options
These will denote specific steps to follow if you purchased the different optional sizes of the machine.
