Safety precautions When using electric tools, the following fundamental safety precautions must always be observed in order to avoid the risk of injury, electric shock and fire hazards. Concealed electric cables or gas and water pipes present a serious hazard if damaged while you are working. [. . . ] Do not operate the tool in the vicinity of flammable liquids or gasses. Do not use it if it is damaged, incomplete or if the controls cannot be operated correctly. Ensure that the insert tools (drill bits, etc. ) are equipped with the appropriate connection end for the chuck system in use and that they are locked in position correctly in the chuck. Use only the recommended original Hilti accessories and auxiliary equipment. Use the tool only for the purposes for which it is intended (see page 8). Before use It is essential that the safety precautions printed in these operating instructions are read and observed before the tool is used. Before it is used for the first time, it is essential that a new battery is charged for 24 hours in normal charging mode or up to 12 hours using the conditioning charging mode, thus permitting "forming" of the battery cells to take place.
