Double Insulated Tools

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 ap- proved system 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.

•WHEN SERVICING, USE ONLY IDENTICAL RE- PLACEMENT PARTS.

•POLARIZED PLUGS. To reduce the risk of elec- trical shock, 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 outlet, reverse the plug. If it still does not fit, contact a qualified electrician to in- stall the proper outlet. To reduce the risk of elec- trical shock, do not change the plug in any way.

Extension Cords

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

•If an extension cord is necessary, a cord with ade- quate size conductors should be used to prevent excessive voltage drop, loss of power or overheat- ing. The table shows the correct size to use, de- pending 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.
