Themachine features an additional drilling function depending on model.It is driven by an electric motor."Chiseling" operating modeThe rotary movement of the electric motor is converted into a stroke movementvia a transmission and a crank gear while in "Chiseling" operating mode.The piston is moved forwards and backwards by the crank gear, this compressesthe air (forward movement) or generates a partial vacuum (backward move-ment). Due to change in pressure the percussion piston is moved forward andbackwards (air cushion percussion system) and hits the tool.While in "Chiseling" operating mode, the drill drive is uncoupled via the safetyclutch and the tool holder bushing is fixed in place to prevent turning in the toolholder."Hammer drilling" operating modeWhile in "Hammer drilling" operating mode, the rotational movement of the motoris transferred to the drive shaft of the drill drive via a clutch. The drive shaft usesgear wheels to turn the tool holder bushing in the tool holder.
