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).
