ELECTRICAL INFORMATION
Grounding instructions
 
IN THE EVENT OF A MALFUNCTION OR BREAKDOWN, grounding provides the path of least 
resistance for electric current and reduces the risk of electric shock. This tool is equipped with an electric cord 
that has an equipment grounding conductor and a grounding plug. The plug MUST be plugged into a 
matching outlet that is properly installed and grounded in accordance with ALL local codes and ordinances. 
 
DO NOT MODIFY THE PLUG PROVIDED. If it will not fit the outlet, have the proper outlet installed by a 
licensed electrician. 
 
IMPROPER CONNECTION of the equipment grounding conductor can result in electric shock. The 
conductor with the green insulation (with or without yellow stripes) is the equipment grounding conductor. If 
repair or replacement of the electric cord or plug is necessary, DO NOT connect the equipment grounding 
conductor to a live terminal. 
 
CHECK with a licensed electrician or service personnel if you do not completely understand the grounding 
instructions or whether the tool is properly grounded. 
 
USE ONLY THREE-WIRE EXTENSION CORDS that have three-pronged plugs and outlets that accept the 
tool's plug as shown in Fig. A. Repair or replace a damaged or 
worn cord immediately.

properly grounded. If you are not sure, have a licensed electrician 
check the outlet.

Guidelines for using extension cords 
 
Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy 
enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage 
resulting in loss of power and overheating. The table below shows the correct size to be used according to 
cord length and nameplate ampere rating. When in doubt, use the next heavier gauge. The smaller the gauge 
number, the heavier the cord.
