Porter-Cable 28-248, 28-475X instruction manual Functional Description

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.

IN ALL CASES, MAKE CERTAIN THE R E C E P TA C L E I N Q U E S T I O N I S P R O P E R LY GROUNDED. IF YOU ARE NOT SURE HAVE A Q U A L I F I E D E L E C T R I C I A N C H E C K T H E RECEPTACLE.

EXTENSION CORDS

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.

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 with changing blades and applying tension to the blade. The Delta Models 28-248 and 28-475X have large 16"x16" cast iron tables that can be tilted 45 degrees to the right and 8 degrees to the left. The band saws also come with a 4" O.D. dust port for connecting the band saws to a dust collector.
