SYMBOLS USD202-2 The followings show the symbols used for tool. V .......................volts n....................no load speed ° A ....................... amperes ....................Class II Construction Hz ..................... hertz .../min................revolutions or reciprocation per minute ................ alternating current ................number of blow FUNCTIONAL DESCRIPTION 003863 1 2 1. Lock button 2. Switch trigger 003864 2 A B 1 1. Switch trigger 2. Reversing switch lever CAUTION: • Always be sure that the tool is switched off and unplugged before adjusting or checking function on the tool. Switch action CAUTION: • Before plugging in the tool, always check to see that the switch trigger actuates properly and returns to the “OFF” position when released. To start the tool, simply pull the switch trigger. Tool speed is increased by increasing pressure on the switch trigger. Release the switch trigger to stop. For continuous operation, pull the switch trigger and then push in the lock button. To stop the tool from the locked position, pull the switch trigger fully, then release it. Reversing switch action CAUTION: • Always check the direction of rotation before operation. • Use the reversing switch only after the tool comes to a complete stop. Changing the direction of rotation before the tool stops may damage the tool. • When you operate the tool in counterclockwise rotation, the switch trigger is pulled only halfway and the tool runs at half speed. For counterclockwise rotation, you cannot push in the lock button. This tool has a reversing switch to change the direction of rotation. Move the reversing switch lever to the position (A side) for clockwise rotation or to the position (B side) for counterclockwise rotation. Selecting action mode Selecting action mode This tool employs an action mode changing knob. Select one of the two modes suitable for your work needs by using this knob. For rotation only, turn the knob so that the arrow on the knob points toward the symbol on the tool body. For rotation with hammering, turn the knob so that the arrow on the knob points toward the symbol on the tool body. CAUTION: • Always set the knob fully to your desired mode symbol. If you operate the tool with the knob positioned half-way between the mode symbols, the tool may be damaged. For Model HR2455 CAUTION: • Do not rotate the action mode changing knob when the tool is running under load. The tool will be damaged. • To avoid rapid wear on the mode change mechanism, be sure that the action mode changing knob is always positively located in one of the three action mode positions. 003573 Rotation with hammering For drilling in concrete, masonry, etc., depress the lock button and rotate the action mode changing knob to the symbol. Use a tungsten-carbide tipped bit. 1 1. Action mode changing knob 1 2 3 1. Rotation with hammering 2. Lock button 3. Action mode changing knob 1 1. Hammering only 003574 Hammering only For chipping, scaling or demolition operations, depress the lock button and rotate the action mode changing knob to the symbol. 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, s...
