Delta 31-280 instruction manual Extension Cords, Changing Voltage

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 tool’s plug. When using an extension cord, be sure to use one heavy enough to carry the current of the tool. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. Figs. 4A and 4B show 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.

CHANGING VOLTAGE

The motor supplied with this tool is a dual voltage, 120/240 Volt, Single Phase motor and is wired for 120 volts.

To operate the tool at 240 volts:

1.DISCONNECT TOOL FROM POWER SOURCE.

2.Remove the motor cover (A) Fig. 5 by loosening the six screws that fasten it to the stand.

3.Remove the brown wire from terminal 2. Connect it to terminal 6 (Fig. 6).

4.Remove the blue wire from terminal 4. Connect it to terminal 2 (Fig. 6). NOTE: The wires have spade-type quick connectors. No wire nuts are required.

5.Replace the motor cover removed in STEP 2.

6.Replace the 120 volt plug (supplied with the motor) with a 240 volt plug that has two flat, current-carrying prongs, and one round or “U” shaped ground prong. (See Fig. 3) Use this plug ONLY with the proper mating 3-conductor grounded receptacle (See Fig. 3).
