Unpacking and Cleaning, Extension Cords

When converted for 230 volt operation, your drill press is intended for use on a circuit that has an outlet like the one illustrated in Fig. C. After conversion for 230 volts, the drill press will have a grounding plug that looks like the plug illustrated in Fig. C.

Make sure the drill press is connected to an outlet having the same configuration as the plug. No adapter is available or should be used when the drill press is converted for 230 volts. If the drill press must be reconnected for use on a different type of electrical circuit, the reconnection should be made by qualified service personnel; and after reconnection, 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.

OPERATING INSTRUCTIONS

FOREWORD

Delta Models 17-925 and 17-990X are 16½" variable speed drill presses. The Delta Models 17-925 and 17-990X have a powerful ¾ HP motor which provides plenty of power for a variety of drilling jobs.

UNPACKING AND CLEANING

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.
