Select the desired speed/torque range using the gear shifter (F) to match the speed and torque to the planned operation. 2. Turn the torque adjustment collar (E) to the desired position. NOTE: Use the lowest torque setting required to seat the fastener at the desired depth. The lower the number, the lower the torque output. 3. Insert the desired fastener accessory into the chuck as you would any drill bit. 4. Make some practice runs in scrap or on unseen areas of the workpiece to determine the proper position of the torque adjustment collar. 5. Always start with lower torque settings, then advance to higher torque settings to avoid damage to the workpiece or fastener. NOTE: When torque is achieved in screwdriving mode, the unit will automatically shut off with a set of short pulses. Drilling (Fig. 4) NOTICE: If drilling thin material, use a wood "back-up" block to prevent damage to the material. 1. Select the desired speed/torque range using the gear shifter (F) to match the speed and torque to the planned operation. Turn the collar (E) to the drill symbol. 2. Use sharp drill bits only. For MASONRY, such as brick, cement, cinder block, etc., use carbide-tipped bits rated for percussion drilling. 3. Always apply pressure in a straight line with the bit. Use enough pressure to keep drill biting, but do not push hard enough to stall the motor or deflect the bit. 4. Hold tool firmly with both hands to control the twisting action of the drill. If model is not equipped with side handle, grip drill with one hand on the handle and one hand on the battery pack. WARNING: Drill may stall if overloaded causing a sudden twist. Always expect the stall. Grip the drill firmly to control the twisting action and avoid injury. 5. IF DRILL STALLS, it is usually because it is being overloaded or improperly used. RELEASE TRIGGER IMMEDIATELY, remove drill bit from work, and determine cause of stalling. DO NOT DEPRESS TRIGGER ON AND OFF IN AN ATTEMPT TO START A STALLED DRILL - THIS CAN DAMAGE THE DRILL. 6. To minimize stalling or breaking through the material, reduce pressure on drill and ease the bit through the last fractional part of the hole. 7. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent jamming. Hammerdrilling (Fig. 5) 1. Select the desired speed/torque range using the gear shifter (F) to match the speed and torque to the planned operation. Turn the collar (E) to the hammerdrill symbol. IMPORTANT: Use carbide-tipped or masonry bits rated for percussion drilling only. 2. Drill with just enough force on the hammer to keep it from bouncing excessively or "rising" off the bit. Too much force will cause slower drilling speeds, overheating, and a lower drilling rate. 3. Drill straight, keeping the bit at a right angle to the work. Do not exert side pressure on the bit when drillling as this will cause clogging of the bit flutes and a slower drilling speed. 14
