Grounded Tools: Tools With Three Prong Plugs; Extension Cords - Chicago Electric 47840 Owner's Manual & Safety Instructions

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.

Grounded Tools: Tools with Three Prong Plugs

1. Tools marked with "Grounding Required" have a three wire cord and three
prong grounding plug. The plug must be connected to a properly grounded
outlet. If the tool should electrically malfunction or break down, grounding
provides a low resistance path to carry electricity away from the user,
reducing the risk of electric shock. (See 3-Prong Plug and Outlet.)
2. The grounding prong in the plug is connected through the green wire inside
the cord to the grounding system in the tool. The green wire in the cord must
be the only wire connected to the tool's grounding system and must never be
attached to an electrically "live" terminal. (See 3-Prong Plug and Outlet.)
3. The tool must be plugged into an appropriate outlet, properly installed and
grounded in accordance with all codes and ordinances. The plug and outlet
should look like those in the preceding illustration.
(See 3-Prong Plug and Outlet.)

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.
8. Protect the extension cords from sharp objects,
excessive heat, and damp or wet areas.
