Anleitung Zusammenfassung
To adjust the drilling speed, rotate the speed control knob located in the center of the Trigger. Turn clockwise to increase speed and counterclockwise to decrease speed. See Figure 2. 7. For continuous drilling, press Trigger, then Trigger lock button on side of handle, and release Trigger. To release lock, depress Trigger. See Figure 2. 8. WARNING! Use both hands during use. 9. Use the Depth Gauge for controlled depth drilling. The Depth Gauge has two sets of markings on opposite ends of the gauge. One is in half inch increments and the other in one-centimeter increments (increments are not precise values, only general guides). 10. Insert bit and tighten Chuck. Loosen Side Handle, place tip of bit against solid surface and extend Depth Gauge until it is against same surface. Determine required hole-depth and retract Gauge accordingly. Tighten Side Handle. 11. To switch between plain drilling and hammering mode (drilling with an oscillating hammer motion), slide the Mode Selector (26) to left or right. The “drill” symbol indicates plain drilling while the “hammer” symbol indicates hammer drilling. See Figure 3. 12. Figure 3Mode Selector (26) (Top View) Drill symbolHammer symbolWARNING! Use this continuous drill function ONLY when drilling soft materials. Do not drill or hammer drill hard materials such as steel or concrete with Lock Button pressed (ON). If drill bit catches on material, the high torque will cause the tool to twist around without stopping. This violent action could cause injury to your hands and arms. It could also damage the Hammer Drill. 13. To prevent accidents, turn off the tool and disconnect its power supply after use. Clean, then store the tool indoors out of children’s reach. Metal Drilling Tips 1. Use high speed steel, carbide or specialty bits for metal drilling. 2. Secure work piece to keep it from moving during the drilling operation. 3. Use a center punch (not included) to create a dimple for the bit to start. 4. Remove Key from Chuck. 5. Start by drilling slowly to keep bit from wandering/skating away from your starting point. 6. As hole is established, increase speed. Do not use so much pressure that bit heats up. This can damage bit and create irregular hole. For hard metal, use cutting oil to keep bit cool. 7. When drilling large holes in metal, start by drilling a smaller pilot hole, then using a larger bit for the final size hole. Wood Drilling Tips 1. Use high speed bits or bits specially designed for wood drilling, such as brad point, spade bits, forstner bits, etc. 2. Secure work piece to keep it from moving during the drilling operation. 3. Start by drilling slowly to keep bit from wandering away from starting point. Increase speed as hole is established. 4. To prevent or reduce “break out” when bit penetrates work piece, clamp a piece of scrap material to back of work piece. 5. Do not lock Trigger in the ON position, as the bit can easily jam in wood and motor must be stopped quickly. Concrete Drilling Tips 1. Use carbide or specialty bits for concrete drilling. 2. Rock and masonry are generally drilled in the hammer (impact) drilling mode. 3. When drilling in walls, start with regular drilling and, once tile is pierced, continue with hammer mode. NOTE: In deep bore holes, occasionally pull the drill bit out to remove dust and chips.

TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION: Turn the Trigger off and unplug the tool from its electrical outlet before performing any inspection, maintenance, or any cleaning procedures. TO PREVENT SERIOUS INJURY FROM TOOL FAILURE: Do not use damaged equipment. If abnormal noise or vibration occurs, have the problem corrected before further use. Cleaning, Maintenance, and Lubrication 1. BEFORE EACH USE, inspect the general condition of the tool. Check for loose hardware, misalignment or binding of moving parts, cracked or broken parts, damaged electrical wiring, and any other condition that may affect its safe operation. 2. AFTER USE, wipe the tool with a clean cloth. 3. PERIODIC...
