  • To switch on the power tool, first slide the lock-off button (2) to the middle and then press and hold the on/off switch (65).

Note: For safety reasons, the on/off switch (65) cannot be locked; it must remain pressed during the entire operation.

  • To switch off, release the on/off switch (65).

If the power tool is operated in the energy-saving ECO mode, the battery life may be up to 20% longer.

If the ECO mode is active, the symbol E is shown on the speed setting/mode indicator (49). In addition, the ECO mode indicator (47) lights up.

The user interface (3) is used to preselect the speed and to indicate the status of the power tool.
