Changing Motor Voltage

WARNING: If not properly grounded, this tool can
cause an electrical shock, particularly when used
in damp locations, in proximity to plumbing, or out
of doors. If an electrical shock occurs there is the
potential of a secondary hazard, such as your
hands contacting the knives.
NOTE: The band saw is prewired at the factory for 120V
operation. Use the following procedure to change motor
voltage. To change to 240V application an additional wire
nut is supplied from the factory. This part is included in
the loose parts.
1. Unplug the band saw before making or changing any
connections. Open the motor junction box cover
located on the side of the motor.
2. Remove and discard the electrical tape from the wire
nuts. Remove wire nuts.
3. Reconnect the leads as shown in the "Wiring Diagram"
section at the rear of manual.
4. Reinstall the wire nuts and wrap with two layers of new
U.L. listed electrical tape per wire nut.
5. Recheck your wiring to the wiring diagrams. Do this so
you can be sure that the wiring is correct.
6. Reinstall the junction box cover.
7. Cut off the 120 volt power cord plug and replace it with
a (3 blade) 240 volt 15 amp U.L. Listed Assembled - on
Plug Cap suitable for 16 AWG Type SJT Cord. (See
illustration of 240V plug & receptacle.) Connect the
power cord white and black leads, respectively, to the

Motor Safety Protection

1. Connect this tool to a power source with the appropri-
ate voltage for your model and a 15-amp branch circuit
with a 15-amp time delay fuse or circuit breaker. Using
the wrong size fuse can damage the motor.
2. If the motor won't start, turn off the power switch imme-
diately and unplug the tool. Check the saw blade to
make sure it turns freely. If the blade is free, try to start
the motor again. If the motor still does not start, refer to
the "Motor Troubleshooting Chart."
3. If the motor suddenly stalls while cutting wood, turn off
the power switch, unplug the tool and free the blade
from the wood. The motor may now be restarted and
the cut finished.
4. Fuses may "blow" or circuit breakers may trip fre-
quently if:

Wire Sizes

NOTE: Make sure the proper extension cord is used and
is in good condition.
The use of any extension cord will cause some loss of
power. To keep this to a minimum and to prevent overheat-
ing and motor burnout, use the table shown to determine
the minimum wire size (A.W.G.) extension cord.
Use only 3-wire extension cords which have 3-prong
grounding type plugs and 3-pole receptacles which
accept the tools plug.
"hot" plug blade terminals and connect the power cord
green grounding wire to the plug ground prong termi-
nal.
8. Plug your band saw into a 220-240V, 15 amp, 3 blade
receptacle.
9. Make certain the receptacle is connected to a 240 volt
A.C. power supply through a 240 volt branch circuit
having at least a 15 amp capacity and protected by a
15 amp time-delay fuse or circuit breaker.

a. Motor Is Overloaded-Overloading can occur if you
feed too rapidly or make too many start/stops in a
short time.
b. Line voltages should not be more than 10% above
or below the nameplate voltage. For heavy loads,
however, the voltage at motor terminals must equal
the voltage specified for your model.
c. Improper or dull saw blade is used.
5. Most motor troubles may be traced to loose or incor-
rect connections, overload, low voltage (such as small
size wire in the supply circuit) or to overly long supply
circuit wire. Always check the connections, the load
and the supply circuit whenever motor doesn't work
well. Check wire sizes and length with the Wire Size
Chart.
