3. Grounded, cord-connected machines intended
for use on a supply circuit having a nominal rating
between 150 - 250 volts, inclusive:
If the machine is intended for use on a circuit that has an outlet
that looks like the one illustrated in Fig. C, the machine will
have a grounding plug that looks like the plug illustrated in Fig.
C. Make sure the machine is connected to an outlet having
the same configuration as the plug. No adapter is available
or should be used with this machine. If the machine must be
re-connected for use on a different type of electric circuit, the
re-connection should be made by qualified service personnel;
and after re-connection, the machine should comply with the
National Electric Code and all local codes and ordinances.

EXTENSION CORDS
Use proper extension cords. Make sure that your extension cord is in good condition and is a 3-wire
extension cord which has a 3-prong grounding type plug and matching receptacle which will accept the machine’s
plug. When using an extension cord, be sure to use one heavy enough to carry the current of the machine. An
undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. Fig. D-1 or D-2, shows
the correct gauge to use depending on the cord length. If in doubt, use the next heavier gauge. The smaller the gauge
number, the heavier the cord.

FUNCTIONAL DESCRIPTION
FOREWORD
Delta Models 28-248 and the 28-475X are 14" wood cutting band saws. The band saws have a quick-tensioning
blade mechanism for ease in changing blades and applying tension to the blade. These models have large 16"x16"
cast iron tables that can be tilted 45° to the right and 8° to the left. The band saws also come with a 4" O.D. dust port
for connecting the band saws to a dust collector.
NOTICE: The photo on the manual cover illustrates the current production model. All other illustrations contained in
the manual are representative only and may not depict the actual color, labeling, or accessories and are intended to
illustrate technique only.
4. Permanently connected machines:
If the machine is intended to be permanently connected, all wiring must be done by a qualified electrician and
conform to the National Electric Code and all local codes and ordinances.
* Three phase operation: Three phase machines are not supplied with a power cord and must be permanently
connected to a building’s electrical system. Extension cords can’t be used with a three phase machine.
