Electrical Requirements
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. The JPL-358 Pen Lathe is equipped with an electric cord
having an equipment-grounding conductor and a grounding plug. 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.
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.
This tool is intended for use on a circuit that has an outlet like the one in illustration A of Figure 1. The
tool has a grounding plug like the grounding plug in illustration A. A temporary adapter, which looks like
the adapter in illustration B, may be used to connect this plug to a two-pole receptacle, as shown in
illustration B, 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. The green colored rigid ear or
tab, extending from the adapter, must be connected to a permanent ground such as a properly grounded
outlet box.
* Canadian electrical codes require extension cords to be certified SJT type or better.
** Use of an adapter in Canada is not acceptable.
