This tool has a reversing switch to change the direction of rotation. Depress the reversing switch lever from the A side for clockwise rotation or from the B side for counterclockwise rotation. When the switch lever is in the neutral position, the switch trigger cannot be pulled. Selecting action mode Rotation with hammering (Fig. 4) For drilling in concrete, masonry, etc., depress the lock button and rotate the change lever so that the pointer points to the H symbol. Use a tungsten- carbide tipped bit. Rotation only (Fig. 5) For drilling in wood, metal or plastic materials, depress the lock button and rotate the change lever so that the pointer points to the M symbol. Use a twist drill bit or wood bit. Hammering only (Fig. 6) For chipping, scaling or demolition operations, depress the lock button and rotate the change lever so that the pointer points to the X symbol. Use a bull point, cold chisel, scaling chisel, etc. CAUTION: • Do not rotate the change lever when the tool is running. The tool will be damaged. • To avoid rapid wear on the mode change mechanism, be sure that the change lever is always positively located in one of the three action mode positions. Installing or removing bit Important: Always be sure that the tool is switched off and the battery cartridge is removed before installing or removing the bit. Clean the bit shank and apply the bit grease provided to it before installing the bit. (Fig. 7) Insert the bit into the tool. Turn the bit and push it in until it engages. (Fig. 8) 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. (Fig. 9) After installing, always make sure that the bit is securely held in place by trying to pull it out. To remove the bit, pull the chuck cover down all the way and pull the bit out. (Fig. 10) Depth gauge (Fig. 11) The depth gauge is convenient for drilling holes of uniform depth. Loosen the clamp screw and adjust the depth gauge to the desired depth. After adjusting, tighten the clamp screw firmly. NOTE: The depth gauge cannot be used at the position where the depth gauge strikes against the gear housing/motor housing. Side grip (Fig. 12) CAUTION: Always use the side grip to ensure operating safety when drilling in concrete, masonry, etc. 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. Bit angle (when chipping, scaling or demolishing) Important: Always be sure that the tool is switched off and the battery cartridge is removed before changing the bit angle. To change the bit angle, depress the lock button and rotate the change lever so that the pointer points to the O symbol. Turn the bit to the desired angle. (Fig. 13) Depress the lock button and rotate the change lever so that the pointer points to the X symbol. (Fig. 14) Then make sure that the bit is securely held in place by turning it slightly. Operation CAUTION: • Always insert the battery cartridge all the way until it locks in place. If you can see the red part on the upper side of the button, it is not locked completely. Insert it fully until the red part cannot be seen. If not, it may accidentally fall out of the tool, causing injury to you or someone around you. • When operating overhead, always make sure the battery cartridge is locked securely so that it will not be fallen out of the tool. If not, it may accidentally fall out of the tool, causing injury to you or someone around you. Hammer drilling operation (Fig. 15) Set the change lever to the H symbol. Position the bit at the location for the hole, then pull the 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 from the hole. By repeating this several times, the hole will be cleaned out. CAUTION: • When the bit begins to break through concrete or if the bit strikes reinforcing rods embedded in concrete, the tool may react dangerously. Maintain good balance and safe footing while holding the tool firmly with both hands to prevent dangerous reaction. 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. Chipping/Scaling/Demolition (Fig. 16) Set the change lever to the X 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. Dri...
