Improperly connecting the grounding wire can result in
electric shock.
Check with a qualified electrician if you are in doubt as to
whether the outlet is properly grounded. Do not modify the
power cord plug provided with the tool. Do not use the tool
if the power cord or plug is damaged. If damaged, have it
repaired by a service facility before use. If the plug will not
fit the outlet, have a proper outlet installed by a qualified
electrician.
Double Insulated tools: tools with two Prong Plugs
Tools marked “Double Insulated” do not
require grounding. They have a special
double insulation system which satisfies
OSHA requirements and complies with the
applicable standards of Underwriters Labo-
ratories, Inc., the Canadian Standard Asso-
ciation, and the National Electrical Code.
(See Outlets for 2-Prong Plug.)
Double insulated tools may be used in either
of the 120 volt outlets shown in the preceding illustration.
(See Outlets for 2-Prong Plug.)
Extension cords
Grounded tools require a three wire extension cord. Double Insulated tools can
use either a two or three wire extension cord.
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 tool damage.
(See table A.)
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.
(See table A.)
When using more than one extension cord to make up the total length, make
sure each cord contains at least the minimum wire size required. (See table A.)
