  • the external communication device 150 or 250 may be connected to the at least one communication line 300.
  • the external communication device 150 or 250 sends the identification tag 460 identifying the handheld machine tool 80 to the suction device 10.
  • the suction device communication device 40 receives the identification code 460 and forwards it, for example, to the control device 37, which recognizes, for example, the type of the hand-held machine tool 80, for example, what amount of particles is to be expected from this hand-held machine tool 80, which suction power corresponding to the identification code 460 is to be provided by the suction device 10 or the like.
  • the control device 37 accordingly sets the function of the suction device 10, for example, such that the suction power of the suction motor 19 is adjustable on the adjusting switch 24, but not below a limit value which allows reliable extraction of the particles generated by the hand-held machine tool 80 ,
  • control device 37 can check whether an operation of the hand-held machine tool 80 with the suction device 10 is even possible if at least one criterion is met. If, for example, it should be noted that the suction device 10 is intended to provide explosion protection in connection with the respective hand-held machine tool and / or at least one predetermined suction power of the suction device 10 is required so that the at least one criterion is met, the control device 37 can determine whether the identification tag 460 is indicated in a table 430 containing a plurality of identification tags. If so, the controller 37 releases the suction device 10 for operation with the hand machine tool 80.
  • the nature of the particles may also be different, including, for example, larger chips or smaller chips. Accordingly, it is expedient for the handheld machine tool 80, for example as an operating parameter 450, to send information about the tool 82 used to the suction device communication devices 40 or 140.
  • the control device 37 can, for example, set cleaning intervals of a cleaning device 9 which cleans a filter 8, which precedes the suction motor 19.
  • the suction device 10 logs on, so to speak, before the start of an operation.
  • the suction device communication device 40 sends an identification code 410 of the suction device 10 and / or at least one operating parameter 400 to the manual machine tool 80.
  • a controller 88 on-board the handheld machine tool 80 checks, based on a check table, whether the identification tag 410 classifies the suction device 10 so that it can be used in conjunction with the handheld machine tool 80. Only then does the controller 88 release the drive motor 81. Otherwise, the controller 88 blocks the drive motor 81, so that, for example, health impairments of a user of the hand-held machine tool 80 can be avoided by non-aspirated particles.
  • the suction device 10 can inform the hand-held machine tool 80, for example, which suction power can be available.
  • the hand-held power tool 80 then reduces, for example, a maximum speed of the drive motor 81, so that even with a maximum switch 87 adjustable speed of the drive motor 81, the suction of the suction device 10 is sufficient to reliably all accumulating particles or at least substantially all particles from the working area of the hand Vacuum machine 80.
  • the external communication devices 150 or 250 and / or the suction device communication devices 40 or 140 based on the respectively received identification code when the 410, 460 and / or the received operating parameters 400, 450 directly generate control signals and / or alarm signals and to the other Send communication equipment.
  • the external communication devices 150 and / or 250 can determine from the identification code 410, for example, that the suction device 10 has to provide a specific output and accordingly sends a control signal 351 that controls the suction device 10 instructed to set a particular power level as a minimum adjustable power level on the control switch 24.
  • a control signal 351 that controls the suction device 10 instructed to set a particular power level as a minimum adjustable power level on the control switch 24.
  • the control signal 351 and a message signal 352 are generated, which is displayed for example by the display 102.
  • the suction device 10 or the suction device communication devices 40, 140 can also be designed in this way.
  • the suction device communication devices 40, 140 and / or the suction device 10 for example the control device 37, use the identification code 460 or the operating parameter 450 to determine which rotational speeds of the drive motor 81 of the handheld machine tool 80 are adjustable or adjustable and accordingly sends a control signal 353 and / or a report signal 354 to the external communication devices 150 or 250.
  • the control signal 353 instructs them to communicate, for example, to the control device 88, which outputs of the drive motor 81 are to be adjustable at the switch 87.
  • the information of the notification signal 354 is displayed on the display 104, for example, so that the operator knows which power ranges to be set on the hand machine tool 80 and / or which tools are usable or the like.
