Chuck Key Holder ASSEMBLY A WARNING Disconnect the power plug from the AC power source before any assembly, adjustments, or adding/removing accessories. Following this preventative step reduces the risk of the drill coming on accidentally and the risk of damage to the workpiece and Injury to the operator. SIDE HANDLE ASSEMBLY • Loosen wing nut located on the side of the handle. • Place circular opening over drill chuck and onto front of drill gear case. • The handle now has a full range of 360° around the drill. • Tighten wing nut. DRILL BIT INSERTION / REMOVAL TIGHTEN LOOSEN Unplug the drill. Never change bits on a live drill. Make sure the bit is undamaged, sharp and free from wood or metal shavings. Foreign material on the bit may keep the chuck from tightening fully. A loose bit may cause injury. Push the bit into the chuck as far as it Make sure the bit is in the center of the chuck. If the bit is off-center, it will not be held securely and may fly loose during use causing serious injury. Insert the chuck key into one of the three chuck holes. Rotate the chuck key clockwise to lock the bit in place. Remove the chuck key. Store the Chuck Key after each use in its holder located at the power cord stem. A WARNING Always run the drill for one minute before drilling to make sure the bit is properly seated. If the bit needs to be adjusted, unplug the drill before touching the bit._ 9 OPERATING THE DRILL A WARNING Dack in the opposit rol and possible s Dack, especially wh In certain situations, the bit may bind and the drill will kick-e direction. This sudden reaction could lead to loss of con-srious injury. Always be prepared for the possibility of kicken breaking through material to complete a hole. Squeeze the trigger switch to turn the tool "ON". Release the trigger switch to turn the tool "OFF". When drilling for extended periods, the "Lock-On" switch may be used, but do not use this switch in situations where the drill is likely to bind or kickback. If kickback does occur, the sudden motion of the tool may make it difficult to release the "Lock-On" switch and turn the drill off. 10 SPEED CONTROL ADJUSTING SWITCH To increase the operating speed of the drill, turn the variable speed control clockwise. To decrease the speed, turn the variable speed control counter clockwise. REVERSING SWITCH LEVER The reversing switch lever reverses the rotation of the drill bit. It is located just above the trigger switch. ALWAYS turn the motor off and let the bit come to a complete stop before moving the switch. Move the switch to the left for a forward rotation of the bit. Move the switch to the right to put the bit into reverse. CAUTION Do not change the direction of a moving bit. Make sure the bit comes to a complete standstill before moving switch. Changing direction while the bit is moving can cause damage to the drill. HAMMER/DRILL SELECTOR • To use the tool as a hammer, move the hammer/drill selector switch to the right. • To use the tool as a drill, move the hammer/drill selector switch to the left. USING THE DEPTH GAUGE When drilling to a preset depth, use the adjustable depth gauge to mark the exact depth needed. • Insert depth gauge into the hole in the side of the handle. • Determine drilling depth needed. depth of • Loosen the handle and lower the gauge until the distance between the end of the depth gauge and the end of the drilling bit equals the required depth. Tighten the handle. • Drill until the material touches the end of the depth gauge. The hole will be the desired depth. DRILLING WOOD • Always clamp the work piece to a steady base. Never hold in your hand or across your legs. • Apply pressure in line with the bit. Applying pressure at an angle could cause the bit to bind or break. • Thin materials that may splinter should be drilled with another piece of wood placed underneath. • Twist bits can be used for wood drilling but will overheat if the flutes are not cleared of wood chips periodically. • To prevent splintering when finishing holes, stop drilling just before the hole breaks through and complete the hole from the other side. DRILLING MASONRY • Always use carbide tip bits for drilling masonry. • Use an even pressure, hard enough to keep the drill biting, but not so hard that the bit spins in the hole. Spinning the bit will dull it quickly. Bricks and similar soft materials will take less pressure than a hard material like concrete. DRILLING METAL • Use an even pressure, hard enough to keep the drill biting, but...
