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. Reversing switch action 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 the position (B side) for counterclockwise rotation. 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. Selecting the 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 mark on the tool body. For rotation with hammering, turn the knob so that the arrow on the knob points toward the mark on the tool body. CAUTION: • Always set the knob fully to your desired mode mark. If you operate the tool with the knob positioned halfway between the mode marks, the tool may be damaged. Torque limiter Torque limiter CAUTION: • As soon as the torque limiter actuates, switch off the tool immediately. This will help prevent premature wear of the tool. • Hole saws, core bits, diamond core bits, etc. 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. ASSEMBLY CAUTION: • Always be sure that the tool is switched off and unplugged before carrying out any work on the tool. 003143 Side grip (auxiliary handle) The side grip swings around to either side, allowing easy handling of the tool in any position. Loosen the side grip by turning it counterclockwise, swing it to the desired position and then tighten it by turning clockwise. 1. Side grip 2. Clamp screw Bit grease (optional accessory) Coat the bit shank head beforehand with a small amount of bit grease (about 0.5 - 1 g; 0.02 - 0.04 oz.). This chuck lubrication assures smooth action and longer service life. 1 2 003150 21 003150 21 Installing or removing the bit Clean the bit shank and apply bit grease before installing the bit. 1.

If the bit cannot be pushed in, remove the bit. Pull the chuck cover down a couple of times. Then insert the bit again. 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. 003163 To remove the bit, pull the chuck cover down all the way and pull the bit out. 003181 Depth gauge The depth gauge is convenient for drilling holes of uniform depth. Insert the depth gauge into the hole in the grip base. Adjust the depth gauge to the desired depth and then tighten the clamp screw to secure the depth gauge. NOTE: • The depth gauge cannot be used at the position where the depth gauge strikes against the tool body. 003186 003186 Use the dust cup to prevent dust from falling over the tool and on yourself when performing overhead drilling opera 1 tions. 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. 003187 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 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 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. 1 002449 Blow-out bulb (optional accessory) After drilling the hole, use the blow-out bulb to clean the dust out of the hole. 1.
