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 approved system by Underwriter’s Laboratories, CSA and Federal OSHA
authorities.
WARNING
Servicing of a tool with double insulation requires care and knowledge of
the system and should be performed only by a qualified service technician.
WARNING
WHEN SERVICING, USE ONLY IDENTICAL REPLACEMENT PARTS.
WARNING
POLARIZED PLUGS. To reduce the risk of electrical 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 install the proper outlet. To
reduce the risk of electrical shock, do not change the plug in any way.
Extension Cords
WARNING
Replace damaged cords immediately .
Use of damaged cords can shock,
burn or electrocute.
WARNING
If an extension cord is necessary, a cord with adequate size conductors
should be used to prevent 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 the tool. If in doubt, use the next heavier gauge. Always use U.L. and CSA
listed extension cords.
