GROUNDING TO PREVENT ELECTRIC SHOCK AND DEATH FROM INCORRECT GROUNDING WIRE 1. CONNECTION: Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do not modify the power cord 2. plug provided with the tool. Never remove the grounding prong from the plug. 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 3. the outlet, have a proper outlet installed by a qualified electrician. Double Insulated Tools: Tools with Two Prong Plugs 4. 5. Outlets for 2-Prong Plug 6. 1. 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 7. of Underwriters Laboratories, Inc., the Canadian Standard Association, and the National Electrical Code. 2. 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.) If you are using one extension cord for more than one tool, add the nameplate amperes and use the sum to determine the required minimum cord size. (See Table A.) If you are using an extension cord outdoors, make sure it is marked with the suffix "W-A" ("W" in Canada) to indicate it is acceptable for outdoor use. Make sure the extension cord is properly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a qualified electrician before using it.

GROUNDING
TO PREVENT
ELECTRIC SHOCK
AND DEATH FROM INCORRECT
GROUNDING WIRE
CONNECTION:
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.
Never remove the grounding
prong from the plug.
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
Outlets for 2‑Prong Plug
1.
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 Laboratories, Inc.,
the Canadian Standard Association,
and the National Electrical Code.
2.
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
1.
Grounded
tools require a three
wire extension cord.
Double
Insulated
tools can use either a
two or three wire extension cord.
2.
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.)
3.
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.)
4.
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.)
5.
If you are using one extension
cord for more than one tool, add
the nameplate
amperes and use
the sum to determine the required
minimum cord size.
(See Table A.)
6.
If you are using an extension cord
outdoors, make sure it is marked with
the suffix “W-A” (“W” in Canada) to
indicate it is acceptable for outdoor use.
7.
Make sure the extension cord is
properly wired and in good electrical
condition.
Always replace a damaged
extension cord or have it repaired by
a qualified electrician before using it.
