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.
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 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.
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.
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 Figure 4 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.
230 Volt, Three Phase Operation
The three-phase model is factory wired for 230
volt, but can be converted to 460 volt if so
desired (see “Converting From 230 Volt to 460
Volt”). You may either install a plug or “hard-
wire” the Band Saw directly to a control panel.
If you are connecting a plug, use a proper UL-
listed plug suitable for 230 volt operation.
