Starting Operation

  • To start the power tool, press and hold the on/off switch (5).
  • Press the lock button (4) to lock the on/off switch (5) in this position.
  • To switch off the power tool, release the on/off switch (5); or, if the switch is locked with the lock button (4), briefly press the on/off switch (5) and then release it.

At low temperatures, the power tool will take a certain amount of time to reach its full impact performance. You can shorten this warm-up time by tapping the power tool's inserted application tool on the ground once.

You can adjust the impact rate of the power tool when it is on by pressing in the on/off switch (5) to varying extents.

Slight pressure on the on/off switch (5) results in a low impact rate. Increased pressure on the switch causes an increase in impact rate.

You can lock the chisel in 12 different positions, allowing you to select the optimum working position for each task.

  • Insert the chisel into the tool holder.
  • Push the chisel adjustment ring (3) forwards and turn the chisel to the required position with the chisel adjustment ring (3).
  • Release the chisel adjustment ring (3) and turn the chisel until it audibly clicks into place.
