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 all local codes and ordinances.
Use proper extension cords. Make sure 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, 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.

FOREWORD
The Delta Model 28-206 is a 1 Hp, 120/240 V, 2 speed unit with a quick blade tensioning device and an enclosed stand.
The Delta Model 28-276 is a ¾ Hp, 120/240 V, 1 speed unit with a quick blade tensioning device and an open stand.
Carefully unpack the machine and all loose items from the shipping container(s). Remove the protective coating from
all unpainted surfaces. This coating may be removed with a soft cloth moistened with kerosene (do not use acetone,
gasoline or lacquer thinner for this purpose). After cleaning, cover the unpainted surfaces with a good quality household
floor paste wax.
