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.

READ AND SAVE ALL INSTRUCTIONS FOR FUTURE USE. TOOL ASSEMBLY WARNING To reduce the risk of injury, always unplug tool before attaching orremoving accessories or makingadjustments. Use only specificallyrecommended accessories. Others may be hazardous. Removing the Chuck (Fig. 1) 1. Open the chuck jaws fully. 2. Remove the screw inside the chuck head. This is a left hand screw, turn clockwise to remove. 3. Hold the spindle with a wrench (Fig. 1). 4. Insert the drill chuck key inside chuck and loosen clockwise by tapping lightly with a rubber hammer. NOTE: To mount the chuck, reverse the instructions above. Installing Bits into Keyed Chucks (Fig. 2) 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 b...
