[. . . ] Due to our continuing programme of research and development, the specifications herein are subject to change without notice. Power supply The tool should be connected only to a power supply of the same voltage as indicated on the nameplate, and can be operated on single-phase AC/DC supply. [. . . ] To secure the handle at a fixed position, first loosen the nut and swing the handle to the desired position for use. If the set bolt turns together with the nut when you secure the nut, see that the projecting portion of the side handle fits into the notch on the head of the set bolt. It is also highly recommended that you wear a dust mask, ear protectors and thickly padded gloves. In cold weather or when the tool has not been used for a long time, let the tool warm up for several minutes by operating it under no load. When chipping into walls, floors or wherever "live" electrical wires may be encountered, DO NOT TOUCH ANY METAL PARTS OF THE TOOL!Hold the tool by the insulated grasping surfaces to prevent electric shock if you chip into a "live" wire. CAUTION: Before plugging in the tool, 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 slide down the lock button. To stop the tool from the locked position, pull the trigger fully, then release it. Turn the tool on and apply slight pressure on the tool so that the tool will not bounce around, uncontrolled. CAUTION: Always be sure that the tool is switched off and unplugged before carrying out any work on the tool. Whenever carbon brushes must be replaced, they cut out the tool automatically.
