Due to our continuing program of research and development, the specifications herein are subject to change without notice. ⷠNote: Specifications may differ from country to country. Intended use The tool is intended for impact drilling in brick, concrete and stone as well as for drilling without impact in wood, metal, ceramic and plastic. [. . . ] Be sure that the speed change lever is set to the correct position before operation. nOTE: · When changing the position from "1" to "3" or from "3" to "1", it may be a little difficult to slide the speed change lever. At this time, switch on and run the tool for a second at the "2" position, then stop the tool and slide to your desired position. cAUTION: · Always set the speed change lever fully to the correct position. If you operate the tool with the speed change lever positioned halfway between the "1" position, "2" position and "3" position, the tool may be damaged. ⷠDo not use the speed change lever while the tool is running. Insert the side grip so that the protrusions on the grip base fit in between the grooves on the tool barrel. Then tighten the grip by turning clockwise. Fit the bit holder into the protrusion at the tool foot on either right or left side and secure it with a screw. When not using the driver bit, keep it in the bit holders. Select one of the three modes suitable for your work needs by using this lever. When changing the position from " " to " ", it may be a little difficult to slide the mode change lever. At this time, switch on and run the tool for a second at the " " position, then stop the tool and slide to your desired position. cAUTION: · Always set the lever correctly to your desired mode mark. If you operate the tool with the lever positioned halfway between the mode marks, the tool may be damaged. Loosen the clamp screw, set to desired position, then tighten the clamp screw. This can be installed on either side of the tool. To install the hook, insert it into a groove in the tool housing on either side and then secure it with a screw. To remove, loosen the screw and then take it out. There is a tremendous and sudden twisting force exerted on the tool/bit at the time of hole breakthrough, when the hole becomes clogged with chips and particles, or when striking reinforcing rods embedded in the concrete. Always use the side grip (auxiliary handle) and firmly hold the tool by both side grip and switch handle during operations. The adjusting ring can be aligned in any torque levels for this operation. [. . . ] Always be sure that the tool is switched off and the battery cartridge is removed before attempting to perform inspection or maintenance. Replace when they wear down to the limit mark. Keep the carbon brushes clean and free to slip in the holders. Both carbon brushes should be replaced at the same time. [. . . ]
