User manual HITACHI DV 18V

[. . . ] Do not use power tools where there is risk to cause fire or explosion. When not in use, tools should be stored in a dry, high or locked up place, out of reach of children and infirm persons. It will do the job better and safer at the rate for which it was intended. Do not force small tools or attachments to do the job of a heavy duty tool. [. . . ] 4) The bit rotates clockwise (viewed from the rear side) by pushing the R-side of the push button. The L-side of the push button is pushed to turn the bit counterclockwise. ) CAUTION Always use the impact drill with clockwise rotation, when using it as an impact drill. 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. Power source Ensure that the power source to be utilized conforms to the power requirements specified on the product nameplate. If the plug is connected to a receptacle while the power switch is in the ON position, the power tool will start operating immediately, inviting serious accident. Extension cord When the work area is removed from the power source, use an extension cord of sufficient thickness and rated capacity. 7) Shift the change lever between the right and left positions to switch easily between IMPACT (rotation and impact) and ROTATION (rotation only), respectively. 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. 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. 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. 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. 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. 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. 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. [. . . ] 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. IMPORTANT Correct connection of the plug The wires of the mains lead are coloured in accordance with the following code: Blue:- Neutral Brown:- Live As the colours of the wires in the mains lead of this tool may not correspond with the coloured markings identifying the terminals in your plug proceed as follows: The wire coloured blue must be connected to the terminal marked with the letter N or coloured black. The wire coloured brown must be connected to the terminal marked with the letter L or coloured red. [. . . ]
