The following is a list of common definitions, terms and phrases used throughout this manual as they relate to this lathe and metalworking in general. Become familiar with these terms for assembling, adjusting or operating this machine. Your safety is VERY important to us at Grizzly! Arbor: A machine shaft that supports a cutting Gib: A tapered wedge located along a sliding tool.
To reduce the risk of these hazards, avoid over- loading the machine during operation and make sure it is connected to a power supply circuit that meets the specified circuit requirements. -16- Model G0776 (Mfd. Since 7/14)
IMPORTANT: Save all packaging materials until you are completely satisfied with the machine and have resolved any issues between Grizzly or the shipping agent. You MUST have the original pack- aging to file a freight claim. It is also extremely helpful if you need to return your machine later.
If you cannot find an item on this list, care- fully check around/inside the machine and packaging materials. Often, these items get lost in packaging materials while unpack- ing or they are pre-installed at the factory. Figure 12. Toolbox inventory. -19- Model G0776 (Mfd. Since 7/14)
