Grounding Instructions

This machine MUST be grounded. In the event of certain malfunctions or breakdowns, grounding reduces the risk of electric shock by providing a path of least resistance for electric current.

the power cord and plug specified under “Circuit requirements for 220V” on the previous page has an equipment-grounding wire and a ground- ing prong. the plug must only be inserted into a matching receptacle (outlet) that is properly installed and grounded in accordance with all local codes and ordinances (see figure below).

Serious injury could occur if you connect the machine to power before completing the setup process. DO NOT connect to power until instructed later in this manual.

No adapter should be used with the required plug. If the plug does not fit the available receptacle, or the machine must be reconnected for use on a different type of circuit, the reconnection must be made by a qualified electrician and comply with all local codes and ordinances.

Serious injury could occur if you connect the machine to power before completing the setup process. DO NOT connect to power until instructed later in this manual.

Improper connection of the equipment-grounding wire can result in a risk of electric shock. The wire with green insulation (with or without yellow stripes) is the equipment-grounding wire. If repair or replacement of the power cord or plug is nec- essary, do not connect the equipment-grounding wire to a live (current carrying) terminal.

Check with a qualified electrician or service per- sonnel if you do not understand these grounding requirements, or if you are in doubt about whether the tool is properly grounded. If you ever notice that a cord or plug is damaged or worn, discon- nect it from power, and immediately replace it with a new one.

Extension Cords

We do not recommend using an extension cord with this machine. If you must use an extension cord, only use it if absolutely necessary and only on a temporary basis.

Extension cords cause voltage drop, which may damage electrical components and shorten motor life. Voltage drop increases as the extension cord size gets longer and the gauge size gets smaller (higher gauge numbers indicate smaller sizes).

Any extension cord used with this machine must contain a ground wire, match the required plug and receptacle, and meet the following require- ments:

Minimum Gauge Size

14 AWG

Maximum Length (Shorter is Better)

50 ft.

G0747 and G0748 specifications

The Grizzly G0747 and G0748 are advanced metal lathes designed for precision machining and versatility, catering to both amateur machinists and professional workshops. These machines stand out in the realm of metalworking equipment, thanks to their robust construction and innovative features.

One of the key attributes of the G0747 and G0748 is their solid cast iron construction, which provides excellent vibration dampening during operation. This enhances stability and precision, crucial for producing high-quality machined parts. Equipped with powerful motors, both models are capable of handling a wide range of materials, from aluminum to harder metals like steel.

The G0747 features a variable speed drive system, allowing users to adjust the spindle speed based on the project at hand. This flexibility is beneficial for tasks that require different cutting speeds, enabling machinists to optimize cutting performance and tool longevity. Its variable speed output ranges, alongside smooth torque delivery, make it ideal for intricate turning operations.

On the other hand, the G0748 includes an advanced digital readout (DRO) system. This feature provides real-time feedback on the machine's position and speed, significantly improving accuracy in measurements during machining tasks. The DRO system allows operators to set precise limits and keep track of their progress, essential for complex projects where exact dimensions are critical.

Both lathes are equipped with a user-friendly interface, making them accessible for beginners while still offering advanced functionalities that seasoned professionals appreciate. They include multiple tooling options, allowing for an expansive range of machining techniques including turning, threading, and drilling.

Moreover, the G0747 and G0748 come with a comprehensive assortment of accessories, such as different types of chucks and tool holders, which further extends their capabilities. The ease of changing tooling and quick setup times are significant advantages for shops aiming for efficiency and versatility in their operations.

In conclusion, the Grizzly G0747 and G0748 metal lathes are exemplary units that balance power, precision, and user-friendliness. Their advanced features, such as variable speed capabilities and digital readouts, equip machinists with the tools necessary to produce exceptional work. Whether for hobbyists or industrial applications, these lathes are built to meet a variety of machining needs with impressive performance and reliability.
