GROUNDING

WARNING

Improperly connecting the grounding wire can result in the risk of electric shock. Check with a qualiﬁed electri- cian if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with the tool. Never remove the grounding prong from the plug. Do not use the tool if the cord or plug is damaged. If damaged, have it repaired by a MILWAUKEE ser- vice 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

Tools marked “Grounding Required” have a three wire cord and three prong grounding plug. The plug must be connected to a prop- erly grounded outlet (See Figure A). If the tool should electrically malfunction or break down, grounding provides a

low resistance path to Fig. A carry electricity away

from the user, reduc- ing the risk of electric shock.

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.

Your tool must be plugged into an appropri- ate outlet, properly installed and grounded in accordance with all codes and ordinances. The plug and outlet should look like those in Figure A.

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 Cana-

dian Standard Associa- tion and the National Electrical Code. Double Insulated tools may be used in either of the 120

volt outlets shown in Fig. B Fig. C Figures B and C.

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, result- ing in loss of power and possible tool damage. Refer to the table shown 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. 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 wire size.

Guidelines for Using Extension Cords

•If you are using an extension cord out- doors, be sure it is marked with the sufﬁx “W-A” (“W” in Canada) to indicate that it is acceptable for outdoor use.

•Be sure your extension cord is prop- erly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a qualiﬁed person before using it.

•Protect your extension cords from sharp objects, excessive heat and damp or wet areas.
