Starting Operation

Pay attention to the mains voltage. The voltage of the power source must match the voltage specified on the rating plate of the power tool.

Switching On and Off

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.

Changing the chiselling position (Vario-Lock) (see figure C)

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.
