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.
IMpORTANT: Servicing of a tool with double insu-
lation requires care and knowledge of the system
and should be performed only by a qualified serv-
ice technician.
WHEN SERVICING, USE ONLY IDENTICAL RE-
PLACEMENT PARTS.
POLARIZED PLUGS. To reduce the risk of electri-
cal 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 elec-
trician to install the proper outlet. To reduce the
risk of electrical shock, do not change the plug in
any way.

Double Insulated Tools

Replace damaged cords immediately. Use of dam-
aged cords can shock, burn or electrocute.
If an extension cord is necessary, a cord with ade-
quate size conductors should be used to prevent ex-
cessive 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.
RECOMMENDED SIZES OF EXTENSION CORDS
120 VOlT AlTERNATING CURRENT TOOlS
NOTE: The smaller the gauge number, the higher
the cord capacity.
