Resumen del manual
to install and remove drill bits without using a key or tools. Operating Instructions Read the entire Important Safety Information section at the beginning of this manual including all text under subheadings therein before set up or use of this product. Tool Set Up To prevent serious injury from accidental operation: Release the Trigger (32) and disconnect from power source before adjusting tool or installing a drill bit. To insert a drill bit, hold the rear ring 1. of the Chuck (5) with one hand while turning the front end clockwise with the other hand to open the jaws. Rev 10g Open the jaws enough to allow the bit to 2. slide into the Chuck. Turn the front ring counterclockwise to tighten the jaws on the bit shank. CAUTION! 3. Be sure the bit is centered on the jaws before tightening firmly (be sure to wear heavy-duty work gloves.) Tug on bit to make sure it is securely attached. WARNING! 4. Do not use dull or damaged bits. Doing so can cause undue stress on the Drill, leading to possible property damage and/or personal injury. Work Piece and Work Area Set Up Designate a work area that is clean and 1. well-lit. The work area must not allow access by children or pets to prevent distraction and injury. Route the power cord along a safe 2. path to reach the work area without creating a tripping hazard or exposing the power cord to possible damage. The power cord must reach the work area with enough extra length to allow free movement while working. Secure loose work pieces using a vise 3. or clamps (not included) to prevent movement while working. There must not be objects, such as utility 4. lines, nearby that will present a hazard while working. General Operating Instructions Plug Power Cord (21) into suitable outlet.1. Use the Forward/Reverse Switch (30) 2. above the Trigger (32) to determine the rotation direction of the Chuck. Slide it to the right side for reverse Chuck rotation. Slide to the left side for forward Chuck rotation. See Figure 1. CAUTION! Allow Chuck to come to complete stop prior to changing its direction of rotation. Squeeze the Trigger (32) to start the 3. tool. The Trigger has a variable speed feature. Pressing it lightly will make the tool operate slowly; pressing more will cause the tool to operate faster. Note: The Speed Limiter Dial can be adjusted to limit the travel of the Trigger. Turning the dial counterclockwise (-) will limit the Trigger movement to low speed settings. Turning the dial clockwise (+) will allow for full Trigger range and faster speeds. To lock the Trigger in the ON position, 4. squeeze the Trigger, pressing in the Lock ON button, and then releasing the Trigger. The tool will operate continuously. To stop the tool, squeeze and release the Trigger. To prevent accidents, turn off the tool 5. and disconnect from power source after use. Clean, then store the tool indoors out of children’s reach. The Drilling Operation Use only well-sharpened bits that are in 1. good condition and appropriate to task. Use firm pressure when drilling, but do 2. not press too hard. Too much pressure will not help the process and will cause bit to overheat, may cause bit to bend or break, cause undue strain on the tool, and may damage the bit or work piece. Pressing too hard may stall the motor. WARNING!3. If motor stalls, release Trigger immediately to prevent damage to the tool. Always drill in a straight line, using built-4. in level as a guide. Bending or twisting bit while drilling may cause the bit to Rev 10g bend or break and may damage the work piece. Back off your pressure when you are 5. about to penetrate the work piece. Keep the motor running when pulling the 6. bit out of a completed hole to prevent the bit from jamming. Metal Drilling Use high speed steel, carbide or 1. specialty bits for metal drilling. Secure the work piece to keep it from 2. moving during the drilling operation. Use a punch to create a dimple for the 3. bit to start. Start by drilling slowly to keep bit from 4. moving away from your starting point. As the hole is established, increase tool 5. speed. Do not go so fast or use so much pressure that the bit heats up. This can damage the bit and create an irregular hole. For hard metal or thick pieces, use cutting oil to keep the bit cool. Since drilling in metal is a slow operation, 6. you may lock the Trigger in the ON position to maintain a constant speed and reduce fatigue. When drilling large holes in metal, start 7. by drilling a smaller pilot hole, then using a larger bit for the final size hole. Wood Drilling Use high carbon bits or bits specially 1. designed for wood drilling, such as brad point, spade bits, forstner bits, etc. Secure the work piece to keep it from 2. moving during the drilling operation. Start by drilling slowly to keep the bit 3. from moving away from your starting point. Increase speed as the hole is established. To prevent or reduce “break out” when 4. the bit penetrates the work piece, clamp a piece of scrap material to the b...
