Double Insulated Tools		Extension Cords

Double insulation is a design concept used in electric power tools which eliminates the need for the three wire grounded power cord and grounded power supply system. It is a recognized and approved sys- tem by Underwriter’s Laboratories, CSA and Federal OSHA authorities.

●Servicing of a tool with double insulation requires care and knowledge of the system and should be performed only by a qualified service technician.

●Replace damaged cords immediately. Use of damaged cords can shock, burn or electrocute.

●If an extension cord is necessary, a cord with adequate size conductors should be used to pre- vent excessive voltage drop, loss of power or overheating. The table shows the correct size to use, depending on cord length and nameplate amperage rating of tool. If in doubt, use the next heavier gauge. Always use U.L. and CSA listed extension cords.

●WHEN SERVICING, USE ONLY IDENTICAL REPLACEMENT PARTS.

●POLARIZED PLUGS. Your tool is equipped with a polarized plug (one blade is wider than the other), this plug will fit in a polarized outlet only one way. If the plug does not fit fully in the out- let, reverse the plug. If it still does not fit, contact a qualified electrician to install the proper outlet. To reduce the risk of electrical shock, do not change the plug in any way.
