Use a bull point, cold chisel, scaling chisel, etc. 1 1 Rotation only ASSEMBLY 1 2 1. Grip base 2. Side grip 3. Loosen 4. Teeth 5. Protrusion 6. Tighten 003575 Rotation only For drilling in wood, metal or plastic materials, depress the lock button and rotate the action mode changing knob to the symbol. Use a twist drill bit or wood bit. Torque limiter The torque limiter will actuate when a certain torque level is reached. The motor will disengage from the output shaft. When this happens, the bit will stop turning. CAUTION: • As soon as the torque limiter actuates, switch off the tool immediately. This will help prevent premature wear of the tool. • Hole saws cannot be used with this tool. They tend to pinch or catch easily in the hole. This will cause the torque limiter to actuate too frequently. CAUTION: • Always be sure that the tool is switched off and unplugged before carrying out any work on the tool. 001295 Side handle (auxiliary handle) 436 5 Always use the side grip to ensure operating safety. Install the side grip so that the teeth on the grip fit in between the protrusions on the tool barrel. Then tighten the grip by turning clockwise at the desired position. It may be swung 360° so as to be secured at any position. 1 2 1 2 Bit shank 2. Bit grease Bit grease Coat the bit shank head beforehand with a small amount of bit grease (about 0.5 - 1 g). This chuck lubrication assures smooth action and longer service life. 001296 Installing or removing the bit Clean the bit shank and apply bit grease before installing the bit. 1 2 1. Bit 2. Chuck cover 1 2 1. Bit 2. Chuck cover 001297 Insert the bit into the tool. Turn the bit and push it in until it engages. After installing, always make sure that the bit is securely held in place by trying to pull it out. 001298 To remove the bit, pull the chuck cover down all the way and pull the bit out. Bit angle (when chipping, scaling or demolishing) Bit angle (when chipping, scaling or demolishing) The bit can be secured at the desired angle. To change the bit angle, depress the lock button and rotate the action mode changing knob to the O symbol. Turn the bit to the desired angle. 1 2 1. Lock button 2. Action mode changing knob 003577 Depress the lock button and rotate the action mode changing knob to the symbol. Then make sure that the bit is securely held in place by turning it slightly. 1 1. Depth gauge 003865 Depth gauge The depth gauge is convenient for drilling holes of uniform depth. Loosen the side grip and insert the depth gauge into the hole in the side grip. Adjust the depth gauge to the desired depth and tighten the side grip. NOTE: • The depth gauge cannot be used at the position where the depth gauge strikes against the gear housing. 001300 Dust cup Use the dust cup to prevent dust from falling over the tool and on yourself when performing overhead drilling operations. Attach the dust cup to the bit as shown in the figure. The size of bits which the dust cup can be attached to is as follows. 003578 1 1. Dust cup Bit diameter Dust cup 5 6 mm (1/4”) - 14.5 mm (9/16”) Dust cup 9 12 mm (15/32”) - 16 mm (5/8”) OPERATION 1 1. Blow-out bulb 003866 Hammer drilling operation 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 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. 001302 Blow-out bulb Use the blow-out bulb to clean out the hole. Chipping/Scaling/Demolition 003867 For Model HR2455 only 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. 001303 1 001303 1 1. Drill chuck assembly MAINTENANCE Drilling in wood or metal Use the optional drill chuck assembly. When installing it, refer to “Installing or removing drill bit” described on the previous page. Set the action mode changing knob to the symbol. You can drill up to 13 mm(1/2”) diameter in metal and up to 32 mm(1-1/4”) diameter in wood. CAUTION: • Never use “rotation with hammering” when the drill chuck assembly is installed on the tool. ...
