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.
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 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. 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
As received from the factory, your sander is wired to run at 115 volt 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 temporary 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 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 3.
It is recommended that the JSG-6DC Belt/Disc Sander, when operated at
115 volt
, be connected to a
grounded and dedicated, minimum 30 amp circuit with a 30 amp circuit breaker or time delay fuse.
Local
codes take precedence over recommendations.

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 sander is supplied with four motor leads that are connected for 115V operation, as shown in Figure 4.
Remove the switch box, and reconnect these four motor leads for 230V operation, as shown in Figure 5.
Re-install the switch box.
