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 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.
● 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.
Extension Cords
● 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.
