When Should I Level the Mill? We recommend that you level your mill when you:

• Initially install the mill, after you’ve installed all major accessories (enclosure, Automatic Tool Changer)

• Move the mill

Additionally, we recommend that you verify the level of your mill:

• Annually, as part of your shop’s preventative maintenance program

• Whenever a major accessory is installed

Many of the MDI line positions go by quickly, so we have included them below.
