Starting operation
- Products that are only sold in AUS and NZ: Use a residual current device (RCD) with a nominal residual current of 30 mA or less.
- 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. Power tools marked with 230 V can also be operated with 220 V.
- Check whether there is visible damage to the collet (1) and clamping nut (2) before each use.
To start the power tool, slide the on/off switch (5) forwards.
To lock the on/off switch (5) in position, push the on/off switch (5) forwards and down until it clicks into place.
To switch off the power tool, release the on/off switch (5); or, if the switch is locked, briefly push the on/off switch (5) backwards and down and then release it.
You can preselect the required speed using the speed preselection thumbwheel (6), even during operation.
The required speed depends on the material being worked and the diameter of the application tool. Observe the maximal allowable speed of the application tool.
Thumbwheel position | No-load speed (min-1) |
|---|---|
1 | 7000 |
2 | 9500 |
3 | 15000 |
4 | 19000 |
5 | 25000 |
6 | 33000 |
The restart protection feature prevents the power tool from uncontrolled starting after the power supply to it has been interrupted.
To restart the tool, set the on/off switch (5) to the off position and then switch the power tool on again.
Note: Rapidly switching the power tool off and on again may trigger the restart protection, meaning the power tool may not start up even if the on/off switch (5) is pressed. Set the on/off switch (5) to the off position and then switch the power tool on again.
