SECTION 4: OPERATIONS

Operation Overview

The purpose of this overview is to provide the nov- ice machine operator with a basic understanding of how the machine is used during operation, so the machine controls/components discussed later in this manual are easier to understand.

Due to the generic nature of this overview, it is not intended to be an instructional guide. To learn more about specific operations, read this entire manual and seek additional training from expe- rienced machine operators, and do additional research outside of this manual by reading "how- to" books, trade magazines, or websites.

To reduce your risk of serious injury, read this entire manual BEFORE using machine.

To reduce risk of eye or face injury from flying chips, always wear approved safety glasses and face shield when operating this machine.

If you are not experienced with this type of machine, WE STRONGLY RECOMMEND that you seek additional training outside of this manual. Read books/magazines or get formal training before beginning any proj- ects. Regardless of the content in this sec- tion, Grizzly Industrial will not be held liable for accidents caused by lack of training.
