Resumen del manual
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 Laboratories, Inc., the Canadian Standard Association, and the National Electrical Code. (See Figure B.) 5. Double insulated tools may be used in either of the 120 volt outlets shown in the following illustration. (See Figure B.) FIGURE B SKU 03670 PAGE 7 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 Figure C, next page.) 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 Figure C.) 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 Figure C.) 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 Figure C.) 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 your 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 your extension cords from sharp objects, excessive heat, and damp or wet areas. "#$% &$ & '**$+2% $; < <" =< "" <" ">?" @ @ @ @ J ?>Q?Z @ @ @ J Z Q?<>=?" @ J Z =?>?" @ Z " [ ?>J?"

If any parts are missing or broken, please call Harbor Freight Tools at the number shown on the cover of this manual as soon as possible. SKU 03670 PAGE 9 ASSEMBLY AND OPERATING INSTRUCTIONS NOTE: For additional information regarding the parts listed in the following pages, refer to the Assembly Diagram on page 14. FIGURE 1 Chuck Belt Hanger Trigger Tool Hanger Loop Lock Button Torque Adjustment Power Cord Directional Switch Level Refer to FIGURE 1 and 2. Warning! Always unplug the unit when changing bits. Warning! After drilling or driving screws, the bit will be extremely hot. Do not touch it until it has had ample time to cool down. Loading Bits 1. To load a bit, hold the back end of the Chuck (#5) FIGURE 2 with one hand, while turning the front end counterclockwise to open the jaws. 2. Insert the bit. 3. Hold the back end of the Chuck (#5) with one hand, while turning the front end clockwise to close and tighten the jaws around the bit shank. 4. With heavy leather gloves on, tug on the bit and make sure it is securely attached. Check that it is straight. Back End Front End Note: Always use sharp bits. Dull or damaged bits may cause undue stress on the drill and possibly break causing injury. Bits are available at Harbor Freight Tools. SKU 03670 PAGE 10 Operation (continued) Refer to FIGURE 1, 2, and 3. Note: When holding the drill in your hand, the Directional Switch points toward the right, the unit will drill forward. When it is pointed to the left, the unit will drill in reverse. Drilling 1. Securely clamp your workpiece. 2. When drilling wood, place the bit at the point to be drilled. If you are drilling a hard, smooth surface, use a punch to mark the drill location. Set the Directional Switch to forward (right). Grasp the handle firmly and slowly squeeze the Trigger. Never force the tool. Only apply light pressure when drilling. If you need more or less torque, use the Torque Adjustment on the Trigger. Turning the Torque Adjustment screw toward the + sign will add more torque. See FIGURE 3. Note: When drilling plastics or plastic coated chip board, follow the same directions as stated in number 2 for wood. Note: If a bit becomes wedged into the workpiece, change the Directional Switch to the reverse position. 3. When drilling metal, always use a punch to mark the drilling position. Use a lubricant to prolong the life of the bit and increase the drilling action with most metals. With steel, tin, and sheet metal use a light machine oil, with aluminum, use paraffin. Do not use lubricants with brass, copper, and cast iron. Grasp the handle firmly and slowly squeeze the Trigger. Never force the tool. Only apply light pressure when ...
