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 (8), 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 | 8000 |
2 | 12000 |
3 | 16000 |
4 | 20000 |
5 | 23000 |
6 | 28000 |
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)/(15) 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)/(15) is pressed. Set the on/off switch (5)/(15) to the off position and then switch the power tool on again.
The power tool is fitted with the Bosch Brake System, a patented electromechanical run-out brake. When the tool is switched off or the power supply is interrupted, the abrasive tool is brought to a complete stop within a few seconds. This means that the run-out time is 70% shorter than for angle grinders without a run-out brake and enables the power tool to be set down sooner.
Note: If the braking effect deteriorates noticeably, the run-out brake has failed. The power tool must be sent to the after-sales service immediately; see the "After-Sales Service and Application Service" section for addresses.
