1.3 Double Insulated Tools: Tools with 2-Prong
Plugs
Tools marked with class II logo are
“double insulated” and do not require
grounding. Double insulated tools may
be used in either of the 120V outlets as
shown.
1.4 Polarized Plug
This tool has a polarized plug (one
blade is wider than the other). To
reduce the risk of electric shock, this
plug is intended to fit into a polarized
outlet only one way. If plug does not fit
fully into the outlet, reverse the plug. If
it still does not fit, contact a qualified
electrician. Do not attempt to modify
the plug in any way.
1.5 Extensions Cords
As the distance from the supply outlet increases, you must use
a heavier gauge extension cord. Using extension cords with
inadequately sized wire causes a serious drop in voltage, resulting
in loss of power and possible product damage. Refer to the table
here to determine the required minimum wire size.

The smaller the gauge number of the wire, the greater the
capacity of the cord. For example, a 14-gauge cord can carry a
higher current than a 16-gauge cord. When using more than one
extension cord to make up the total length, be sure each cord
contains at least the minimum wire size required.
GUIDELINES FOR USING EXTENSION
CORDS
•
If you are using an extension cord outdoors, be sure it is
marked with the suffix “W-A” (“W” in Canada) to indicate it
is acceptable for outdoor use.
•
Ensure your extension cord is properly wired and in good
electrical condition. Always replace a damaged extension
cord or have it repaired by a qualified technician before
using it.
•
Protect your extension cords from sharp objects, excess
heat and damp or wet areas.
