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 Lab-
oratories, CSA and Federal OSHA authorities.
IMPORTANT: Servicing of a tool with double insulation
requires care and knowledge of the system and
should be performed only by a qualified service
technician.
Grounded tools must be plugged into an outlet
properly installed and grounded in accordance with all
codes and ordinances. Never remove the grounding
prong or modify the plug in any way. Do not use any
adaptor plugs. Check with a qualified electrician if you
are in doubt as to whether the outlet is properly
grounded.
If the tools should electrically malfunction or break down,
grounding provides a low resistance path to carry electricity
away from the user. Improper grounding can shock, burn or
electrocute. Grounded tools are equipped with three
conductor cord and three prong type plugs. Before plugging
in the tool be certain the outlet voltage supplied is within the
voltage marked on the nameplate. Do not use "AC only"
rated tools with a DC power supply.
Replace damaged cords immediately.

WARNING
Use of damaged cords can shock, burn
or electrocute.
Always use proper extension cord. If

WARNING
an extension cord is necessary, a cord
with adequate size conductors should be used to
prevent excessive voltage drop, loss of power or over-
heating. 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.
NOTE: The smaller the gauge number, the heavier the cord.

"SAVE THESE INSTRUCTIONS!"
WHEN SERVICING, USE ONLY IDENTICAL REPLACE-
MENT PARTS.
POLARIZED PLUGS. If your tool is equipped with a polar-
ized 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 electric shock, do not change the plug in any way.
