  • the machine tool in particular the element, can be set up so that the fragrance is released into the environment above a limit temperature of the element.
  • the limit temperature may correspond to a limit or a temperature outside an operating temperature range of the element and/or the machine tool.
  • the limit temperature can be at least 40°C, for example 80°C or 120°C, or between 180 and 240°C, for example 200°C. It can be below an ignition temperature of a material of the element. In particular, it can be below a melting point of a material of the element.
  • the limit temperature can be a maximum of 300 °C. For example, it can be at most 200°C, in particular less than 140°C, for example 100°C. It can be below an evaporation temperature, in particular that of water. The limit temperature can also be below a point for a thermal runaway, for example of an accumulator and/or a battery pack.
  • the machine tool in particular the element, can be set up such that the fragrance is released when a mechanical load limit, for example a limit pressure, is exceeded.
  • a mechanical load limit for example a limit pressure
  • the machine tool, in particular the element can be set up to release the fragrance when pressure is applied to a predetermined breaking point, which corresponds at least to the limit pressure.
  • the fragrance is part of a coating of the element.
  • the fragrance can be applied as a coating to the element or at least to a region of the element.
  • the fragrance can thus be located in particular on an outside of the element. It can therefore be released into the environment particularly easily.
  • the element has a container that contains at least a portion of the fragrance.
  • a container that contains at least a portion of the fragrance.
  • Such a container makes it possible, for example, to store larger quantities of the fragrance. Larger amounts of the fragrance can thus be released. This allows for a more pronounced perception of the fragrance by the user.
  • the user can also perceive the fragrance on construction sites or the like when otherwise particularly adverse conditions prevail on the construction site, for example with regard to noise and/or dust or the like.
  • the fragrance released can develop a strong odor of at least 2 OLF, preferably at least 10 OLF, particularly at a distance of 1 m from the machine tool.
  • the fragrance can have an odor strength of at least 25 OLF.
  • this can correspond to the strength of an odor from a smoker. This means that a particularly good contrast to any other odors that may otherwise prevail is also possible in places such as the construction site.
  • the energy source comprises the fragrance.
  • the energy source can be a battery pack and/or an accumulator. It is also conceivable that the energy source includes power electronics.
  • the energy source can include and/or be a power supply, for example a switched-mode power supply of the battery pack and/or a mains power supply.
  • a critical limit temperature for example in the range between 80 and 150° C., for example in the range from 110 to 130° C., this heating no longer subsides, even if the discharge current or the charging current are reduced. A so-called thermal runaway can thus occur. There is a risk of smoke and/or flames forming. In such a case, the user can be put at considerable risk by the machine tool.
  • the energy source in particular the accumulator and/or the accumulator pack, has the fragrance.
  • the energy source Before the energy source reaches its critical limit temperature, it can release the fragrance.
  • the limit temperature can be selected accordingly. The release of the fragrance can thus warn the user. For example, he can switch off the machine in good time and/or let it cool down before thermal runaway can occur.
  • the fragrance can be particularly noticeable, for example chosen to have an unpleasant scent. This can therefore prompt a user, in particular instinctively, to have the machine tool checked by a third party, for example, and/or not to continue using the machine tool, at least for the time being.
  • the machine tool in particular the element, has an acoustic signal generator.
  • the acoustic signal generator can include a loudspeaker. It can also be in the form of a wireless interface. The wireless interface can transmit audio be set up. Then the machine tool can communicate with a remote speaker via the wireless interface.
  • the remote loudspeaker can, for example, be arranged and/or formed on and/or in a piece of clothing and/or a piece of equipment of the user, for example in and/or on a protective helmet.
  • the acoustic signal generator can be set up to emit a signal tone. It is preferably set up to start and in particular to generate the signal tone in the same time period, in particular at the same time, as the fragrance is released.
  • the fragrance can include a gaseous substance, particularly within the operating temperature range and/or at room temperature, for example between 18 and 25°C.
  • the fragrance can have a gas dissolved in a carrier liquid.
  • the fragrance can include H 2 S, in particular in a low concentration, which rules out or at least sufficiently minimizes any health risk to the user or third parties.
