Preparation Overview

The purpose of the preparation section is to help you prepare your machine for operation. The list below outlines this basic process. Specific steps for each of these points will be covered in detail later in this section.

The typical preparation process is as follows:

1.Unpack the lathe and inventory the contents of the box/crate.

2.Clean the lathe and its components.

3.Identify an acceptable location for the lathe and move it to that location.

4.Level the lathe and either bolt it to the floor or place it on mounts.

5.Assemble the loose components and make any necessary adjustments or inspections to ensure the lathe is ready for operation.

6.Check/lubricate the lathe.

7.Connect the lathe to the power source.

8.Test run the lathe to make sure it functions properly.

9.Perform the spindle break-in procedure to prepare the lathe for operation.
