Grounding Requirements

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.

For 220V operation: This machine is equipped with a power cord that has an equipment-ground- ing wire and a grounding plug (similar to the figure below). The plug must only be inserted into a matching receptacle (outlet) that is prop- erly installed and grounded in accordance with all local codes and ordinances.

For 110V operation: The plug specified under “Circuit Requirements for 110V” on the previ- ous page has a grounding prong that must be attached to the equipment-grounding wire inside the included power cord. The plug must only be inserted into a matching receptacle (see below) that is properly installed and grounded in accor- dance 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

12 AWG

Maximum Length (Shorter is Better)

50 ft.

Voltage Conversion

The voltage conversion MUST be performed by a qualified electrician. To perform the voltage conversion, follow 110V Conversion on the next page. If the diagram included on the motor con- flicts with the one in this manual, the motor may have changed since the manual was printed. Use the diagram provided on the motor.
