If the speed remains constant in the engagement speed range over a predetermined period of time, this can be interpreted as an indication that the tool can not move, since the operator in the engagement speed range usually full throttle, so that the speed increases rapidly in Einkuppeldeldiere Colour and the clutch engages quickly.
  • the constant speed is a largely constant speed. In an internal combustion engine, speed fluctuations occur within one engine cycle due to the design.

It can be provided for resetting the power set several criteria and return the service to operating performance once one of the criteria is met.
  • the predetermined time is up to about 10 s.
  • the predetermined time during which the further drive motor increases the power delivered for driving the tool at least about 5 s.

  • the drive motor of about 5 lithium-ion batteries can be powered. These batteries can be charged during operation of the engine 8.
  • an additional torque in the order of about 1 Nm can be generated.
  • the predetermined time after which the power is reset to the operating power is up to about 10 s.
  • the predetermined time is at least about 5 s.
  • the engine 8 may also be provided to change the amount of combustion air supplied to the engine 8, for example by adjusting the end stop 38 in the in Fig. 3 dashed position shown. As a result, the amount of combustion air supplied to the internal combustion engine 8 is increased, so the mixture supplied to the internal combustion engine 8 is emaciated. This results in an increase in performance.
  • Fig. 9 schematically shown for the ignition timing ZZP.
  • the ignition timing is adjusted from the ignition ZZP 1 initially to a previous ignition ZZP 2 and then to a slightly later ignition ZZP 3 , and then to be adjusted until the third time t 3 between the ignition ZZP 2 and ZZP 3 .
  • One corresponding zigzag-shaped course results for the power P of the internal combustion engine 8, as in Fig. 8 is indicated schematically by the line 46.
  • a wave-shaped course of the power P and the ignition timing ZZP or a sudden change between two ignition times and thus between two power levels may also be advantageous.
  • the operator can also operate the operating element 15.
  • the operation of the operating element 15 causes an increase in the operating power P 1 to an increased power P 2 or P 3 .
  • the increased power can be maintained over a given period or until reaching a predetermined, elevated temperature of the internal combustion engine 8, to then be set back to the operating power P 1 again. If the increased power P 2 , P 3 is so low that it is suitable for continuous operation, provision may also be made for the power to be reset to the operating power P 1 only when the operator releases the operating element 15.
