English Shocks - Active Vibration Control (Fig. 2) For best vibration control, hold the tool with one hand on the main handle (E) and the other hand on the side handle (A). Apply just enough pressure so the hammer is approximately mid-stroke. The hammer only needs enough pressure to engage the internal active vibration control. Applying too much pressure will not make the tool drill faster and active vibration control will not engage. SDS Chuck (Fig. 6) To insert bit, insert shank of bit about 3/4" (19 mm) into chuck (L). Push and rotate bit until it locks in place. The bit will be securely held. To release bit, pull the sleeve (M) back and remove the bit. FIG. 6 L M Drilling (Fig. 2) WARNING: To reduce the risk of personal injury, ALWAYS operate the tool with the side handle properly installed. Failure to do so may result in the side handle slipping during tool operation and subsequent loss of control. Hold tool with both hands to maximize control. NOTICE: If drilling thin material, use a wood "back-up" block to prevent damage to the material. 1. Turn the mode selector (D) to the drill symbol (I). 2. Use sharp drill bits only. For WOOD, use twist bits, spade bits, power auger bits or hole saws. For METAL, use high-speed steel twist drill bits or hole saws. Use a cutting lubricant when drilling metals. The exceptions are cast iron and brass which should be drilled dry. 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. 12
