Grounding Instructions

Electri cal co nnect ions must b e made b y a quali fied el ectrici an in complian ce with

all relevant codes. This machine must be properl y grounded to help preven t electri cal shock and possible fa t a l in jury.

In the event of a malfunction or breakdown, groundi ng 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-gr ounding conductor and a groundi ng plug. The pl ug must be plugged into a matc hing outlet that is properly installed and grounded in accor danc e with all local codes and ordinances.

Do not modify the plug provided. If it will not fit the outl et, have the proper outl et installed by a qualif ied 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-gr ounding conduct or. If repai r or replacem ent of the electri c cord or plug i s 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 gr ounded. Use only three wire ex tension cords that have thr ee- pr ong gr ounding plugs and three-pole receptac les that accept the tool’s plug.

Repair or replace a dam aged or worn cord im mediately.

115 Volt Operation

As received fr om the factory, your sander is wired to run at 115 v olt operation. This sander when wired for 115 volts, is intended for use on a circuit that has an outlet and a plug that looks the one illustrated in Figure 2. A temporar y adapter , which looks like the adapter illustrated in Figure 3, may be used to connect this plug to a two-pole receptacle, as shown in Figure 3 if a properly grounded outlet is not available. The temporary adapter should only be used until a properly grounded out let can be installed by a qualified elec tr ic ian. This adapter is not applicable in Canada. The green colored rigid ear, lug, or tab, extending from the adapter, must be connect ed to a permanent ground such as a properly grounded outlet box, as shown in Fi gur e 3.

It is recommended t hat t he JSG - 6DC Belt/Disc Sander, when operated at 115 volt , be connec ted to a grounded and dedicated, minimum 30 amp circuit wit h a 30 amp circuit breaker or time delay fuse. Local

codes take preceden ce over recommendations.

Figure 2 Figure 3

230 Volt Operation

If 230V, singl e- phase operat ion is desired, the followi ng instructions must be followed:

1. Disconnect the m ac hine from the power source.

2. This sander is supplied with four motor leads that are connected for 115V operation, as shown in

Figure 4. Remove the switch box, and reconnect t hese four motor leads for 230V operation, as shown in Figure 5. Re-install the switch box.

3. The 115V att achment plug (shown in F igure 6) suppli ed with the sander, must be replaced with a

UL/CSA listed plug suitable for 230V operation (shown in Figure 7). Contact your local authorized JET servic e center or qual ified el ectri cian for proper procedures to instal l the pl ug. The sa nder must comply with all l oc al and national codes after the 230 volt plug is installed.

4. The band saw with a 230 volt plug should only be connected to an outlet having the same

configuration (see Figure 7). No adapter i s available or should be used with the 230 volt plug.

Important: In all cases (115 or 230 volts), m ake certain the rec eptacle in quest ion is properl y grounded. If you are not sure, have a regi ster ed electrician check the rec eptacle.

It is recom mended that the JSG -6DC Belt/Disc Sander, when operated at 230 vo lt, be connected to a grounded and dedicat ed, minimum 15 am p circuit with a 15 amp cir cuit br eaker or tim e delay fuse. Local codes take preceden ce over recommendations.

Extens ion Cords

If an ext ension cord is necessary, make sure the cord r ating is suitabl e for the amperage l isted on the machine’s mot or plat e. An undersized c ord will cause a drop i n line v oltage r esulting in loss of power and overheating.

Use the chart in Figure 7 as a general guide in cho osi ng the correc t size extension cord for the Sander. If in doubt, use the next heav ier gauge. The smaller the gauge number, the heavier the cord.
