GROUNDING
EXTENSION CORDS
ASSEMBLY
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 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 Tools marked “Grounding Required” have a three wire cord and three prong grounding plug. The plug must be connected to a properly grounded outlet (See Figure A). 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.
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 ap- propriate outlet, properly installed and grounded in accordance with all codes and ordinances. The plug and
outlet should look like those in | Fig. A |
Figure A. |
Double Insulated Tools:
Tools with Two Prong Plugs
Tools marked “Double Insulated” do not require grounding. They have a special double insula- tion system which satisfies OSHA requirements and complies with the applicable standards of Underwriters Laboratories, Inc.,
the Canadian Standard Asso- ciation and the National Elec- trical Code. Double Insulated tools may be used in either of
the 120 volt outlets shown in Fig. B Fig. C Figures B and C.
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. 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 outdoors, be sure it is marked with the suffix
•Be sure your extension cord is properly 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.

Ring Clamp, Extension, and Side Handle for Right Angle Drive Unit
For D-handle drill with Right Angle Drive Unit:
A ring clamp, extension, and side handle are sup- plied with the Right Angle Drive Unit. When using a right angle drive unit, attach the side handle to the ring clamp. Do not use the extension when using the ring clamp. The ring clamp with attached side handle clamps onto the right angle drive unit and can swivel 360° and locked tight in any position.

NOTE: If you have an extra ring clamp with at- tached side handle and extension with attached side handle, do not use the extension with attached side handle when using the right angle drive unit. Remove it from the tool.
WARNING To prevent personal injury, always remove the chuck key from the chuck after each use.
Installing Bits into Keyed Chucks
Be sure that the shank of the bit and the chuck jaws are clean. Dirt particles may cause the bit to line up improperly. Do not use bits larger than the maxi- mum recommended capacity of the drill because gear damage or motor overloading may result. For best performance, be sure that the bits are properly sharpened before use.
1. Unplug the tool. | Chuck jaws |
2.Open the chuck jaws wide enough to insert a bit. Allow the bit to strike the bottom of the chuck. Center the bit in
the chuck jaws and tighten Chuck key hole the jaws by hand to align the bit.
3.Place the chuck key into each of the three holes in the chuck, turning it clockwise to tighten the chuck securely.
NOTE: Never use a wrench or means other than a chuck key to tighten or loosen the chuck.
4.To remove the bit, insert the chuck key into one of the holes in the chuck and turn it counterclock- wise.
