Electrical Connections
A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and
should be protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which
have 3-prong grounding type plugs and matching receptacle, which will accept the machine’s plug. Before connecting
the machine to the power line, make sure the switch is in the Off position and be sure that the electric current is of the
same characteristics as indicated on the machine. All line connections should make good contact. Running on low
voltage will damage the machine.
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.
1. All grounded, cord-connected tools:
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 3-wire extension cords that have 3-prong grounding plugs and 3 pole receptacles that accept the tool's plug.
Repair or replace damaged or worn cord immediately.
2. Grounded, cord-connected tools intended for use on a supply circuit having a nominal rating less than
150 volts:
This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in Sketch A in Figure 1.
The tool has a grounding plug that looks like the plug illustrated in Sketch A in Figure 1. A temporary adapter, which
looks like the adapter illustrated in Sketch B and C, may be used to connect this plug to a 2 pole receptacle as shown
in Sketch C if a properly grounded outlet is not available. The temporary adapter should be used only until a properly
grounded outlet can be installed by a qualified electrician. This adapter is not permitted in Canada. The green-
colored rigid ear, lug, and the like, extending from the adapter must be connected to a permanent ground such as a
properly grounded outlet box.
Figure 2

3. Grounded, cord- connected tools intended for use on a supply circuit having a nominal rating between
150 - 250 volts, inclusive.
This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in Sketch D in Figure 1.
The tool has a grounding plug that looks like the plug illustrated in Sketch D in Figure 1. Make sure the tool is
connected to an outlet having the same configuration as the plug. No adapter is available or should be used with this
tool. If the tool must be reconnected for use on a different type of electric circuit, the reconnection should be made by
qualified service personnel; and after reconnection, the tool should comply with all local codes and ordinances.
4. Permanently connected tools:
This tool should be connected to a grounded metal permanent wiring system; or to a system having an equipment-
grounding conductor.
Converting from 115 to 230 Volt
Remove the cover of the push button switch and consult the diagram inside the cover. This diagram is also shown in
Figures 3 and 4. (The diagram inside the cover takes precedence – always check it first ).
Disconnect the machine from the power source.
This mortiser is supplied with four leads that are connected for 115V operation, as shown in Figure 3. Reconnect
these four leads for 230V operation, as shown in Figure 4.
The 115V attachment plug (shown in A, Figure 2) must be replaced with a UL/CSA listed plug suitable for 230V
operation (shown in D, Figure 2). The mortiser must comply with all local and national codes after the 230 volt plug is
installed.
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.
Figure 3 Figure 4
Extension Cords
If an extension cord 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 Figure 5 as a general guide in choosing the correct size extension cord for the Bandsaw. If in doubt, use the
next heavier gauge. The smaller the gauge number, the heavier the cord.
