ELECTRICAL CONNECTIONS
WARNING: Make sure unit is off and disconnected
from power source any time wiring is inspected.
POWER SOURCE
Band Saw is prewired for 120 volt, 60 HZ power source.
See figure wiring schematic on page 8.
The motor is designed for operation on the voltage and
frequency specified. Normal loads will be handled safe-
ly on voltages not more than 10% above or below the
specified voltage.
Running the unit on voltages which are not within the
range may cause overheating and motor burn-out.
Heavy loads require that the voltage at motor terminals
be no less than the voltage specified. Power supply to
the motor is controlled by a single pole toggle switch.
GROUNDING INSTRUCTIONS
WARNING: Improper connection of equipment
grounding conductor can result in the risk of electrical
shock. Equipment should be grounded while in use to
protect operator from electrical shock.
• Check with a qualified electrician if grounding
instructions are not understood or if in doubt as to
whether the tool is properly grounded.
This tool is equipped with an approved 3-conductor
cord rated at 150V and a three prong grounding type
plug (see Figure 17) for your protection against shock
hazards.
• Grounding plug should be plugged directly into a
properly installed and grounded 3- prong grounding-
type receptacle, as shown (Figure 17).

• D--on-_ _o-ral---{__pr---_any man-
ner. In the event of a malfunction or breakdown,
grounding provides a path of least resistance for
electrical shock.
WARNING: Do not permit fingers to touch the termi-
nals of plug when installing or removing from outlet.
• Plug must be plugged into matching outlet that is
properly installed and grounded in accordance with
all local codes and ordinances. Do not modify plug
provided. If it will not fit in outlet, have proper outlet
installed by a qualified electrician.
• Inspect tool cords periodically, and if damaged, have
repaired by an authorized service facility.
• Green (or green and yellow) conductor in cord is the
grounding wire. If repair or replacement of the elec-
tric cord or plug is necessary, do not connect the
green (or green and yellow) wire to a live terminal.
Where a 2-prong wall receptacle is encountered, it
must be replaced with a properly grounded 3-prong
receptacle installed in accordance with National Electric
Code and local codes and ordinances.
WARNING: This work should be performed by a quali-
fied electrician.
A temporary 3-prong to 2-prong grounding adapter (see
Figure 18) is available for connecting plugs to a two
3ole outlet if it is properly grounded.

Do not use a 3-prong to 2-prong grounding adapter
unless permitted by local and national codes and
ordinances. (A 3-prong to 2-prong grounding adapter
is not permitted in Canada.) Where permitted, the
rigid green tab or terminal on the side of the adapter
must be securely connected to a permanent electri-
cal ground such as a properly grounded water pipe,
a properly grounded outlet box or a properly ground-
ed wire system.
Many cover plate screws, water pipes and outlet boxes
are not properly grounded. To ensure proper ground,
grounding means must be tested by a qualified electri-
cian.
240 VOLT OPERATION
• To use the band saw with a 240V, single-phase
power supply, have a qualified electrician attach a
230 volt, 20/30A 3-prong plug onto band saw line
cord and install the proper connectors and recepta-
cles to power supply.
• See wiring diagram for motor wiring instructions.
EXTENSION CORDS
• The use of any extension cord will cause some drop
in voltage and loss of power.
• Wires of the extension cord must be of sufficient size
to carry the current and maintain adequate voltage.
• Use the table to determine the minimum wire size
(A.W.G.) extension cord.
• Use only 3-wire extension cords having 3-prong
grounding type plugs and 3-pole receptacles which
accept the tool plug.
• If the extension cord is worn, cut, or damaged in any
way, replace it immediately.
