[. . . ] Due to the continuing program of research and development, the specifications herein are subject to change without prior notice. Power supply The machine should be connected only to a power supply of the same voltage as indicated on the nameplate, and can only be operated on single-phase AC supply. [. . . ] Then install the locator by pushing it firmly back onto the locking sleeve. When driving into walls, floors or wherever ``live'' electrical wires may be encountered, DO NOT TOUCH ANY METAL PARTS OF THE MACHINE!Hold the machine only by the insulated grasping surfaces to prevent electric shock if you drive into a ``live'' wire. Do not touch the bit or the workpiece immediately after operation; they may be extremely hot and could burn your skin. CAUTION: Before plugging in the machine, always check to see that the switch trigger actuates properly and returns to the ``OFF'' position when released. For continuous operation, pull the trigger and then push in the lock button. To stop the machine from the locked position, pull the trigger fully, then release it. A speed control screw is provided so that maximum machine speed can be limited (variable). Turn the speed control screw clockwise for higher speed, and counterclockwise for lower speed. NOTE: Even with the switch on and motor running, the bit will not rotate until you fit the point of the bit in the screw head and apply forward pressure to engage the clutch. Use the reversing switch only after the machine comes to a complete stop. Charging the direction of rotation before the machine stops may damage the machine. CAUTION: Always be sure that the machine is switched off and unplugged before carrying out any work on the machine. To maintain product safety and reliability, repairs, maintenance or adjustment should be carried out by Makita Authorized Service Center. [. . . ] The use of any other accessories or attachments might present a risk of injury to persons. The accessories or attachments should be used only in the proper and intended manner. [. . . ]
