Side handle Loosen Tighten Fig. 6 To attach a depth gauge on the side handle, insert the gauge into the U-shaped groove on the side handle, adjust the position of the depth gauge in accordance with the desired depth of the hole, and firmly tighten the side handle grip.

IMPACT to ROTATION changeover (Fig. 8) Shift the change lever between the right and left positions to switch easily between IMPACT (rotation and impact) and ROTATION (rotation only), respectively. To bore holes in hard materials such as concrete, stone and tiles, shift the change lever to the right- hand position (as indicated by the mark). The drill bit operates by the combined actions of impact and rotation. To bore holes in metal, wood and plastic, shift the change lever to the left-hand position (as indicated by the mark). The drill bit operates by rotational action only, as in the case of a conventional electric drill. CAUTION . Do not use the Impact Drill in the IMPACT function if the material can be bored by rotation only. Such action will not only reduce drill efficiency, but may also damage the drill tip. . Operating the Impact Drill with the change lever in mid-position may result in damage. When switching, make sure that you shift the change lever to the correct position. Change lever Impact Rotation Fig. 8 9. High-speed/Low-speed changeover: Prior to changing speed, ensure that the switch is in the OFF position, and the drill has come to a complete stop. To change speed, rotate the gear shift dial as indicated by the arrow in Fig. 9. The numeral “1” engraved on the drill body denotes low speed, the numeral “2” denotes high speed. If it is hard to turn the gear shift dial, turn the chuck slightly in either direction and then turn the gear shift dial again. Gear shift dial Fig. 9 HOW TO USE 1. Switch operation . When the trigger is depressed, the tool rotates. When the trigger is released, the tool stops. . The rotational speed of the drill can be controlled by varying the amount that the trigger switch is pulled. Speed is low when the trigger switch is pulled slightly and increases as the trigger switch is pulled more. . The desired rotation speed can be pre-selected with the speed control dial. Turn the speed control dial clockwise for higher speed and counterclockwise for lower speed. (Fig. 10) . Pulling the trigger and pushing the stopper, it keeps the switched-on condition which is convenient for continuous running. When switching off, the stopper can be disconnected by pulling the trigger again. CAUTION If the L-side of push button is pressed for reverse bit rotation, the stopper cannot be used. Speed control dial Low speed Switch trigger Stopper Fig. 10 High speed 2. Drilling . When drilling, start the drill slowly, and gradually increasing speed as you drill. . Always apply pressure in a straight line with the bit. Use enough pressure to keep drilling, but do not push hard enough to stall the motor or deflect the bit. . To minimize stalling or breaking through the material, reduce pressure on drill and ease the bit through the last part of the hole. . If the drill stalls, release the trigger immediately, remove the bit from the work and start again. Do not click the trigger on and off in an attempt to start a stalled drill. This can damage the drill. . The larger the drill bit diameter, the larger the reactive force on your arm. Be careful not to lose control of the drill because of this reactive force. To maintain firm control, establish a good foothold, use side handle, hold the drill tightly with both hands, and ensure that the drill is vertical to the material being drilled. MAINTENANCE AND INSPECTION 1. Inspecting the drill bits Since use of an abraded drill bits will cause motor malfunctioning and degraded efficiency, replace the drill bits with a new one or resharpening without delay when abrasion is noted. 2. Inspecting the mounting screws Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so could result in serious hazard. 3. Maintenance of the motor The motor unit winding is the very “heart” of the power tool. Exercise due care to ensure the winding does not become damaged and/or wet with oil or water. 4. Inspecting the carbon brushes For your continued safety and electrical shock protection, carbon brush inspection and replacement on this tool should ONLY be performed by a Hitachi Authorized Service Center. 5. Replacing supply cord If the supply cord of Tool is damaged, the Tool must be returned to Hitachi Authorized Service Center for the cord to be replaced. 6. Service parts list CAUTION: Repair, modification and inspection of Hitachi Power Tools must be carried out by a Hitachi Authorized Service Center. This Parts List will be helpful if presented with the tool to the Hitachi Authorized Service Center when requesting repair or other maintenance. ...
