Harbor Freight Tools 6842 Extension Cords, Grounding Instructions, 125 V~ 3-Prong Plug and Outlet

Grounding Instructions

To prevent electric shock and death from

incorrect grounding wire connection

Read and follow these instructions:

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.

Grounding

Pin

125 V~ 3-Prong Plug and Outlet

(for up to 125 V~ and up to 15 A)

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.)

4.This pump is intended for use on a circuit that has an outlet that looks like the one illustrated above in 125 V~ 3-Prong Plug and Outlet. The pump has a grounding plug that looks like the plug illustrated above in 125 V~ 3-Prong Plug and Outlet.

5.The outlet must be properly installed and grounded in accordance with all codes and ordinances.

6.Do not use an adapter to connect this pump to a different 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.
