Release the button to lock rod into position. When drilling with the depth rod, stop when end of rod reaches surface of material. Bit and Bit Holder WARNING: Burn Hazard. ALWAYS wear gloves when changing bits. Accessible metal parts on the tool and bits may get extremely hot during operation. Small bits of broken material may damage bare hands. WARNING: Do not attempt to tighten or loosen drill bits (or any other accessory) by gripping the front part of the chuck and turning the tool on. Damage to the chuck and personal injury may occur. The rotary hammer can be fitted with various chisel bits depending on the desired application. Use sharp drill bits only. Bit Reccomendations • 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. SDS Plus Bit Holder (Fig. D) NOTE: Special adapters are needed to use the SDS Plus bit holder with straight shank bits and hexagonal screwdriver bits. Refer to Optional Accessories. To insert a drill bit or other accessory 1. Insert the shank of the bit about 3/4" (19 mm) into SDS Plus tool holder 7 . 2. Push and rotate bit until it locks in place. The bit will be securely held. 3. To release bit, pull the sleeve 13 back and remove the bit. 7 To remove the bit, pull back the locking sleeve and pull the bit out. OPERATION WARNING: To reduce the risk of serious personal injury, turn unit off and disconnect it from power source before making any adjustments or removing/installing attachments or accessories. An accidental start-up can cause injury. Proper Hand Position (Fig. E) WARNING: To reduce the risk of serious personal injury, ALWAYS use proper hand position as shown. WARNING: To reduce the risk of serious personal injury, ALWAYS hold securely in anticipation of a sudden reaction. Proper hand position requires one hand on the mounted side handle, with the other hand on the main handle. Fig. E SHOCKS Active Vibration Control® System For best vibration control, hold the tool as described in Proper Hand Position and apply just enough pressure so the damping device on the main handle is approximately mid stroke. The hammer only needs enough pressure to engage the active vibration control. Applying too much pressure will not make the tool actuate faster and active vibration control will not engage. Overload Clutch In case of jamming of a drill bit, the drive to the drill spindle is interrupted by the overload clutch. Due to the resulting forces, always hold the tool with both hands and take a firm stance. After the overload, release and depress the trigger to re-engage drive. 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
