Grounding Instructions

1.75 HP Single Phase Motor

This machine 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. The plug must be plugged 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 equipmentgrounding 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 equipmentgrounding 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. Use only three wire extension cords that have three-prong grounding plugs and three-pole receptacles that accept the tool’s plug.

Repair or replace a damaged or worn cord immediately.

115 Volt Operation

If your band saw's Stock No. is 710750, it is wired from the factory for 115 volt operation. The power cord has a plug that looks like A, Fig. 1. and is used in an outlet that looks like B, Fig. 1. A temporary adapter with a grounding ear secured with a screw (C, Fig. 1) may be used to connect this plug to a two-pole receptacle 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 grounding 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 C, Fig. 1.

Figure 1

230 Volt Operation

If 230V, single phase operation is desired, the following instructions must be followed:

1.Disconnect the machine from the power source.

2.This band saw is supplied with four motor leads that are connected for 115V operation as shown in A, Fig. 2. For 230V operation reconnect the leads as shown in B, Fig. 2.

3.The 115V attachment plug supplied with the band saw (C, Fig. 2) must be replaced with a UL/CSA listed plug suitable for 230V operation (D, Fig. 2). Contact your local Authorized JET Service Center or qualified electrician for proper procedures to install the plug. The band saw must comply with all local and national codes after the 230V plug is installed.

4.The band saw with a 230V plug should only be connected to an outlet having the same configuration (D, Fig. 2). No adapter is available or should be used with the 230V plug.

Important: In all cases (115 or 230 volts), make certain the receptacle in question is properly grounded. If you are not sure, have a registered electrician check the receptacle.

Grounding Instructions

3 HP Single Phase Motor

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 equipmentgrounding 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 equipmentgrounding 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.

230 Volt Operation

If your band saw's Stock No. is 710751, it is wired from the factory for 230 volt operation You may either install a plug or “hard-wire” the band saw directly to a control panel.

If connecting a plug, use a proper UL/CSA listed 2-pole, 3-wire grounding plug suitable for 230V operation.

If the band saw is to be hard-wired to a panel, make sure a disconnect is available for the

operator. During hard-wiring of the band saw, make sure the fuses have been removed or the breakers have been tripped in the circuit to which the band saw will be connected. Place a warning placard on the fuse holder or circuit breaker to prevent it being turned on while the machine is being wired.

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 Table 1 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.
