4. You can lock the Trigger in the ON position by squeezing the trigger, pressing in the Lock Button, and releasing the Trigger. The tool will operate continuously. To stop the tool, squeeze and release the Trigger. 5. Use only well-sharpened bits that are in good condition and appropriate to the task. 6. Use firm pressure when drilling, but do not press too hard. Too much pressure will cause the bit to overheat, may cause the bit to bend or break, cause undue strain on the tool, and may damage the workpiece. Pressing too hard may stall the motor. 7. If the motor stalls, release the Trigger immediately to prevent damage to the tool. 8. Only drill in a straight line. Bending or twisting the bit while drilling may cause the bit to bend or break and may damage the workpiece. 9. Back off your pressure if you are about to penetrate the other side of the workpiece. 10. Keep the motor running when pulling the bit out of a completed hole to prevent the bit from jamming. Metal Drilling 1. Use high speed steel, carbide, TiN coated, or specialty bits for metal drilling. 2. Secure the workpiece to keep it from moving during the drilling operation. 3. To make starting the hole easier, use a punch to create a dimple at the hole center. 4. Unless drilling into cast iron or brass use a cutting lubricant. 5. Start by drilling slowly to keep the bit from moving away from your starting point. 6. As the hole is established, increase tool 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, use cutting oil to keep the bit cool. 7. Since drilling in metal is a slow operation, you may lock the Trigger in the ON position to maintain a constant speed and reduce fatigue. 8. 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 1. Use high speed bits or bits specially designed for wood drilling, such as brad point, spade bits, forstner bits, etc. 2. Secure the workpiece to keep it from moving during the drilling operation. 3. Start by drilling slowly to keep the bit from moving away from your starting point. Increase speed as the hole is established. 4. To prevent or reduce “break out” when the bit penetrates the workpiece, clamp a piece of scrap material to the back of the workpiece. 5. Do not lock the Trigger in the ON position, as the bit can easily jam in wood and the motor must be stopped quickly. After Use To prevent accidents, disengage the trigger, disconnect the tool’s power supply, allow the bit to cool completely, and remove the bit after use. Clean, then store the tool indoors out of children’s reach. Maintenance and Servicing Procedures not specifically explained in this manual must be performed only by a qualified technician. TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION: Make sure that the Power Switch/Trigger is in the off.position and unplug the tool from its electrical outlet before performing any procedure in this section. 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, • damaged cord/electrical wiring, • cracked or broken parts, and • any other condition that may affect its safe operation. 2. AFTER USE, wipe external surfaces of the tool with clean cloth. 3. WARNING! If the supply cord of this power tool is damaged, it must be replaced only by a qualified service technician. Chuck (1) Replacement 1. Release the Trigger and unplug the tool from its electrical outlet. 2. Open the Chuck jaws fully. 3. Remove the Chuck Screw (44) inside the Chuck Jaws by turning it counterclockwise. 4. Switch the Direction Switch to the reverse direction. Plug the Power Cord into a suitable outlet. 5. Hold the Chuck ring with a gloved hand and gently squeeze the trigger with your other hand. 6. The Chuck should come off in your gloved hand. 7. Install the new Chuck by reversing the above steps. Carbon Brush Service If the Carbon Brushes are damaged or worn, they must be replaced by a qualified service technician. Improper service may result in the double insulation system being compromised. Troubleshooting Problem Possible Causes Likely Solutions Tool will not start. 1. Cord not connected. 2. No power at outlet. 3. Tool’s thermal reset breaker tripped (if equipped). 4. Internal damage or wear. (Carbon brushes or switch, for example.) 1. Check that cord is plugged in. 2. Check power at outlet. If outlet is unpowered, turn off tool and check circuit breaker. If breaker is tripped, make sure circuit is right capacity for tool and circuit has no other loads. 3. Turn off tool and allow to cool. Press reset button on tool. 4. Have technician service tool. Tool operates slowly. 1. Fo...
