006386 Dust cup 5 Dust cup 9 Bit diameter 6 mm (1/4") - 14.5 mm (9/16") 12 mm (15/32") - 16 mm (5/8") OPERATION Hammer drilling operation After drilling the hole, use the blow-out bulb to clean the dust out of the hole. Chipping/Scaling/Demolition 009131 Set the action mode changing knob to the symbol. Position the bit at the desired location for the hole, then pull the switch trigger. Do not force the tool. Light pressure gives best results. Keep the tool in position and prevent it from slipping away from the hole. Do not apply more pressure when the hole becomes clogged with chips or particles. Instead, run the tool at an idle, then remove the bit partially from the hole. By repeating this several times, the hole will be cleaned out and normal drilling may be resumed. CAUTION: • There is a tremendous and sudden twisting force exerted on the tool/bit at the time of hole break-through, when the hole becomes clogged with chips and particles, or when striking reinforcing rods embedded in the concrete. Always use the side grip (auxiliary handle) and firmly hold the tool by both side grip and switch handle during operations. Failure to do so may result in the loss of control of the tool and potentially severe injury. NOTE: Eccentricity in the bit rotation may occur while operating the tool with no load. The tool automatically centers itself during operation. This does not affect the drilling precision. Blow-out bulb (optional accessory) 1. Blow-out bulb 1 002449 009132 Set the action mode changing knob to the symbol. Hold the tool firmly with both hands. Turn the tool on and apply slight pressure on the tool so that the tool will not bounce around, uncontrolled. Pressing very hard on the tool will not increase the efficiency. Drilling in wood or metal 1. Chuck adapter 1 2. Keyless drill chuck 009134 2 1 2 1. Sleeve 2. Ring 009135 Use the optional drill chuck assembly. When installing it, refer to "Installing or removing the bit" described on the previous page. Set the action mode changing knob so that the pointer points to the symbol. CAUTION: • Never use "rotation with hammering" when the drill chuck assembly is installed on the tool. The drill chuck assembly may be damaged. Also, the drill chuck will come off when reversing the tool. • Pressing excessively on the tool will not speed up the drilling. In fact, this excessive pressure will only serve to damage the tip of your bit, decrease the tool performance and shorten the service life of the tool. 8
