Grounding Instructions

Electrical connections must be made by a qualified electrician in compliance with all relevant codes. This machine must be properly grounded to help prevent electrical shock and possible fatal injury.

This machine must be grounded. In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock.

Improper connection of the equipment- grounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes, is the equipment- grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal.

Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded.

Repair or replace a damaged or worn cord immediately.

Make sure the voltage of your power supply matches the specifications on the motor plate of the Band Saw. The machine should be connected to a dedicated circuit.

Extension cords

The use of an extension cord is not recommended for this Band Saw. But if one is necessary, make sure the cord rating is suitable for the amperage listed on the machine’s motor plate. An undersize cord will cause a drop in line voltage resulting in loss of power and overheating.

Use the chart in Figure 4 as a general guide in choosing the correct size cord. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

230 Volt, Three Phase Operation

The three-phasemodel is factory wired for 230 volt, but can be converted to 460 volt if so desired (see “Converting From 230 Volt to 460 Volt”). You may either install a plug or “hard- wire” the Band Saw directly to a control panel.

If you are connecting a plug, use a proper UL- listed plug suitable for 230 volt operation.
