Grounding Instructions

General Information

This Band Saw must be grounded while in use to protect the operator from electric shock.

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. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug that looks similar to the plug in Figure 15. The plug must be inserted into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a qualified electrician.

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.

Figure 15

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.

115 Volt Operation

As received from the factory, your band saw is ready to run at 115-volt operation. This band saw is intended for use on a circuit that has an outlet and a plug that looks like the one illustrated in Figure 4. An adapter with a grounding ear (Figure 16) may be used temporarily to connect this plug to a two-pole

receptacle as shown (Figure 11), if a properly grounded outlet is not available. The temporary adapter should only be used until a properly grounded outlet can be installed by a qualified electrician. This adapter is not applicable in Canada. The green colored rigid ear, lug, or tab, extending from the adapter, must be connected to a permanent ground such as a properly grounded outlet box, as shown in Figure 5.

Extension Cords

Use only three wire extension cords that have three-prong grounding plugs and three-pole receptacles that accept the tool’s plug.

Make sure the cord is in good condition and heavy enough to carry the current your band saw will draw. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. Table 1 shows the correct size to use depending on cord length and the ampere rating on your machine’s nameplate. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

Repair or replace a damaged or worn cord immediately.
