WARNING Improperly connecting the grounding wire can result in the risk of elec- tric shock. Check with a qualified electrician 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 appropriate outlet, properly installed and grounded in ac- cordance with all codes and ordinances. The plug and outlet should look like those in Figure A. Fig. 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 Figures B and C.
Fig. B Fig. 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 “W-A” (“W” in Canada) to indicate that it is acceptable for outdoor use.
•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.

INSTRUCTIONS FOR FUTURE USE.
WARNING To reduce the risk of injury, always unplug tool before attaching or remov- ing accessories or making adjustments. Use only specifically recommended accessories. Others may be hazardous.
Installing Bits into Keyed Chucks
1.Unplug tool.
2.Open the chuck jaws wide enough to insert the bit. Be sure the bit shank and chuck jaws are clean. Dirt particles may prevent the bit from lining up properly.
3.Insert the bit into the chuck. Center the bit in the chuck jaws and lift it
about 1/16" off of the bottom. Tighten the chuck jaws by hand to align the bit.
4.Place the chuck key in 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.
5.To remove the bit, insert the chuck key into one of the holes in the chuck and turn it coun- terclockwise.
Bit Selection
•Use sharp bits. Sharp bits are less likely to bind when drilling.
•Use the proper bit for the job. There are many types of bits designed for specific purposes. Check the information on the bit's packaging for proper usage.
•Do not use bits larger than the rated capacity of the drill. Gear damage or motor overload may result (see "Specifications").
Side Handle
The side handle can be installed on either side of the tool. To install the side handle, thread it into the socket on the desired side of the tool and tighten it securely.
Handle Rotation
The djustable switch handle allows the user to adjust the handle to three positions (90° apart) for optimum operating position.
1.Unplug the tool.
2.Press in and hold the handle rotation release button and rotate the switch handle to one of the three handle positions.
3.Release the handle rotation release button. The adjustable handle has detents which allow the handle to snap into position. Make sure the handle snaps firmly into position and does not rotate.
The tool will not operate if the handle is not locked securely in one of the three positions.

WARNING To reduce the risk of injury, wear safety goggles or glasses with side shields.
Chuck Removal
This tool is equipped with
a threaded spindle to hold Fig. 2 the chuck. Before removing
the chuck, unplug the tool and open the chuck jaws. A left-handed thread screw is located inside the chuck to prevent the chuck from loosening when the tool is operated in reverse direc- tion. Remove the screw by
turning it clockwise. To remove the chuck, hold the tool so that only the side of the chuck rests firmly and squarely on a solid workbench. Insert the chuck key or a chuck remover bar in one of the keyholes. Turn the chuck so the key is at about a 30° angle to the bench top and strike the key sharply with a hammer so the chuck turns in a counterclockwise direction (looking from the front of the tool). This should loosen the chuck from the spindle which has a right hand thread making it easy to remove the chuck by hand.
NOTE: When replacing the chuck, always replace the left hand thread screw in the chuck.
